<span id="Issue: MouseSensitivty"></span>

=== Issue - Mouse sensitivity reduced ===
 +
Symptoms: Mouse sensitivity inside any interior is about half that of the value in exteriors.
 +
 +
* Cause-1: "[https://geckwiki.com/index.php?title=ImageSpace Image Space]" systems can configure the base display effects for a cell or worldspace. This would allow designers to drive post-processed "film" effects through the editor, giving much greater control and more of a "film" feel. Some of the effects include blurring, coloring, and HDR/Bloom effects. The ImageSpace form can be opened from the [https://geckwiki.com/index.php/World_Spaces World Spaces] menu.  Mods can make edits which damage how these work.
 +
:* Solution-1: The mod "[https://www.nexusmods.com/newvegas/mods/42847/ PWV - Project Wasteland Vision]" makes some edits to "[https://geckwiki.com/index.php?title=ImageSpace_Modifier ImageSpace Modifier (IMOD)]" records for explosions, plasma, and scope FX.  Removing those edits with [http://www.nexusmods.com/newvegas/mods/34703/? FNVedit] resolved the problem for the reporting user.
 +
 +
* Cause-2: Mouse driver, especially some brand "additional features" such as accelerators.
 +
:* Solution-2a: Check the vendor brand support forums to see if there are any similar reports.
 +
:* Solution-2b: Start troubleshooting by disabling any optional mouse driver features, test, and then add desired features one at a time.
 +
:* Solution-2c: If you have more than one mouse available, try swapping out brands.
 +
:* Solution-2d: Try an older version of the driver as well, as later versions often drop support/testing for older games.
 +
:* Solution-2e: There are hidden interactions between the Audio, Mouse, and Video drivers.  If there has been a recent update to one of these, test by rolling it back to the previous functional version to see if there is an improvement.

">Anytime the game "Crashes to the Desktop" (CTD) it's typically going to generate an error message in the Windows Eventlog because the game engine was not able to predictably handle the error.  Please see the "Windows Error Messages" section of the wiki "[http://wiki.nexusmods.com/index.php/How_to_read_most_Bethesda_game_error_logs How to read most Bethesda game error logs]" article.
 +
 +
Logs generated by the game itself (not Windows) are found in the game folder, where the "FalloutNV.EXE" file is located.
 +
 +
Checking such logs should always be your first step, as separating "Windows System" from "Game" generated errors will save you from fruitlessly spending lots of time looking in the wrong direction for the cause.

:* Solution-1: Those experiencing this problem are recommended to try setting the NVSR INI file "Master" section to ''bHookCriticalSections= 0'', which will disable the use of "CriticalSections" features and the heap related algorithm and size settings in NVSR. (The ''bFastExit'' fix still reportedly works.)  Some have found it necessary to discontinue use of NVSR completely.  Others have found that they could implement partial solutions (detailed below as "other" solutions).  "Your mileage may vary."  Note that this may re-introduce some stuttering and depressed FPS if using large texture replacement images (e.g. greater than 2048x2048).

:* Solution-2: Those experiencing this problem who still want to continue using NVSR can try setting the NVSR INI file "Master" section to ''bHookCriticalSections= 0'', which will disable the use of "CriticalSections" features and the heap related algorithm and size settings in NVSR. (The ''bFastExit'' fix still reportedly works.)  Some have found it necessary to discontinue use of NVSR completely.  Others have found that they could implement partial solutions (detailed below as "other" solutions).  "Your mileage may vary."  Note that this may re-introduce some stuttering and depressed FPS if using large texture replacement images (e.g. greater than 2048x2048).
  
:* Solution-2: If "Solution-1" eliminates the CTD problem, or once you have installed the Win10 April 2018 SCU "1803/Redstone 4" system update, you may be interested in trying the configuration posted by user '''redmaxblower''' [http://forums.nexusmods.com/index.php?/topic/249379-new-vegas-stutter-remover/page-188#entry59460386 here] in the NVSR thread which restores much of NVSR's stutter reduction functionality.  It includes '''ENBLocal.ini''' settings for '''ENB Series''' users as well.

:* Solution-3: It has been found that you can set ''bHookCriticalSections= 1'', and then ''iDefaultMode = 1'' in the "CriticalSections" subsection of "sr_New_Vegas_Stutter_Remover.ini".  The "1" value just means NVSR uses the vanilla mechanism anyway.  Setting "iDefaultMode =" to anything other than "1" seems to cause the problem.  (It defaults to "3".)

<span id="Issue: Grenade throw always falls at my feet"></span>
 
=== Issue - Grenade throw always falls at my feet ===
 
* Cause: The "grenade throw" (thrown explosive) weapon has been separated in FO3 and FNV from other "throwing" weapons and is now based upon "explosives skill".  The "grenade throw" key is not clearly documented in the list of [http://fallout.wikia.com/wiki/Fallout:_New_Vegas_(PC) PC Controls for Mouse and Keyboard].
 
:* Solution-1: Once a "grenade type"/"thrown explosive" is selected, just press and hold the "attack/fire" key/button for a couple of seconds.  The longer you hold it, the further the distance thrown (depending in part upon your aim and trajectory).
 
:: NOTE: [http://fallout.wikia.com/wiki/Thrown_explosive thrown explosives] doesn't work as well as expected in VATS mode as explained in that section of the link.
 
  
:*Solution-2: [http://www.nexusmods.com/newvegas/mods/40040/? Project Nevada] has an option to have the distance thrown based on your Strength (STR) instead of the default of "explosives" skill, in addition to using a "hotkey" to combine the selection and throw.
+
=== Issue - Controls - GamePad Support missing ===
 +
Symptoms: GamePad or Controller does not natively recognize key and mouse controls.
  
:* Solution-3: There are also two other "grenade key" mods that are intended to make "grenade" (explosive) throwing easier:
+
* Cause: The game does not provide built-in support for the device.
::* [http://www.nexusmods.com/newvegas/mods/38808/? Grenade Hotkey] by vivanto

=== Issue - How to determine what keystrokes are being passed ===
+
<span id="Issue: How to remove a game controller's default button bindings"></span>
Sometimes "strange things happen" when you press a key and you wonder just what keystrokes were being sent.
 
  
* Cause: Either a mechanical fault in the keyboard or a remapped key function in the software.  Unfortunately there is no universal way to tell just which software has remapped conflicting keys.  These are usually "context specific", meaning they are part of the application and depend upon what it is expecting at that particular moment.  In the case of mods, the last to assign the key mapping "wins".
+
=== Issue - Controls - How to remove a game controller default button bindings ===
 +
* Cause: The game lacks a "User Interface" or "Menu" option to change the default keys assigned to console-game type controller buttons.
  
:* Solution: Software has been developed for showing even unprintable keystrokes (i.e. mouse-clicks) in real-time for streaming screencasts.  This can be used for troubleshooting as well.  The following are representative examples of available free programs:

=== Issue - HUD-UI-Menu messed up or unreadable or missing ===
+
<span id="Issue: Mods don't seem to have controller support"></span>
* Cause-1: You are using an HUD-UI-Menu mod such as [http://ui.darnified.net/wip/DUIFONV/v1/DUINVv04.7z DarNified UI] (DarnUI) which requires fonts other than the vanilla provided ones to display properly.
 
 
 
:* Solution-1: DarNified UI comes with a set of "DarN" fonts which must be added to the INI files, but there are other fonts available such as:
 
::* [http://www.nexusmods.com/newvegas/mods/40471/? Alternative fonts for DarNified UI]
 
::* [http://www.nexusmods.com/newvegas/mods/51066/? Alternative Fonts Pack for DarNifiedUI (with cyrillic support)]
 
::* [http://www.nexusmods.com/newvegas/mods/60847/? HD More Alternate Fonts for DarNified UI] (in double resolution)
 
:: DarnUI instructions to edit the "Fallout_default.ini" file come from the [http://forums.bethsoft.com/topic/1143482-wipzbeta-darnified-ui-nv/ DarnUI support thread], but it is recommended to edit all three INI files to be sure ("Fallout_default" in the game root folder and the two in the "Users" folder).  The mod [http://www.nexusmods.com/newvegas/mods/54611/? DarnifiedUI Configuration] is a script to automatically make the edits to the default INI file.
 
:: Manual edit instructions are to replace the existing [Fonts] section with the following:
 
<pre>
 
[Fonts]
 
; sFontFile_1=Textures\Fonts\Glow_Monofonto_Large.fnt
 
sFontFile_1=Textures\Fonts\DarN_FranKleinBold_14.fnt
 
; sFontFile_2=Textures\Fonts\Monofonto_Large.fnt
 
sFontFile_2=Textures\Fonts\DarN_FranKleinBold_16.fnt
 
sFontFile_3=Textures\Fonts\Glow_Monofonto_Medium.fnt
 
; sFontFile_4=Textures\Fonts\Monofonto_VeryLarge02_Dialogs2.fnt
 
sFontFile_4=Textures\Fonts\DarN_Sui_Generis_Otl_10.fnt

sFontFile_8=Textures\Fonts\Glow_Futura_Caps_Large.fnt
 
sFontFile_9=Textures\Fonts\NVFont_Test.fnt
 
</pre>
 
:: Note a semi-colon (";") at the beginning of a line "comments out" that line so it is not read but remains for reference.  Other alternative fonts can be used in place of the "DarN_<style>_<size>.fnt" entries, but in that instance it is recommended to add them and comment out the DarN fonts as well.  The "<size>" portion of the name is the number of "points tall" for that font. A large number equals a larger character size, so "6" is very small (short) and "24" is quite large (tall).  Either "10" or "12" is normal for most text.
 
 
 
* Cause-2: An XML file is missing an expected element.  Usually this is caused by a mod installation overwriting the XML file in question.
 
 
 
* Solution-2: It can get complicated.  Read this [http://wiki.nexusmods.com/index.php/HUD-UI-Menu_issues HUD-UI-Menu issues] wiki article.

=== Issue - Controls - Remapping the ''ammo swap'' hotkey from key -2- ===
Monitor is set to a higher than 1920x1080 resolution.
 
 
 
* Cause: FNV was designed for monitor resolutions common prior to 2010. "In 2010, 27-inch LCD monitors with the 2560 × 1440-pixel resolution were released by multiple manufacturers including Apple." - [https://en.wikipedia.org/wiki/Display_resolution Wikipedia on "Display resolution"].  "High Definition" (1920x1080, 16:9 aspect ratio) "FHD standard" was generally considered "high end" for gaming.  Newer monitors may have a higher default resolution.
 
 
 
:* Solution: Use a lower, more standard (in 2010) display resolution.  (Note the LED/Plasma monitors have a default resolution according to the screen size and "aspect ratio".  Lower resolutions may not fill the screen, resulting in "black borders" (e.g. "letterbox style").  "Windowed mode" may be a way around this visual problem.)  See the Wikipedia article quoted above for more on the subject, including a table of "resolution standards".

:* Solution: Edit the "Items | Weapon" entry with GECK so the first and second "Mod Info" tab slots under "Game Effects" are not emptyTypically this will mean moving the second and third slot entries up by one.

+
=== Issue - Grenade throw always falls at my feet ===
 +
* Cause: The "grenade throw" (thrown explosive) weapon has been separated in FO3 and FNV from other "throwing" weapons and is now based upon "explosives skill".  The "grenade throw" key is not clearly documented in the list of [http://fallout.wikia.com/wiki/Fallout:_New_Vegas_(PC) PC Controls for Mouse and Keyboard].
 +
:* Solution-1: Once a "grenade type"/"thrown explosive" is selected, just press and hold the "attack/fire" key/button for a couple of seconds.  The longer you hold it, the further the distance thrown (depending in part upon your aim and trajectory).
 +
:: NOTE: [http://fallout.wikia.com/wiki/Thrown_explosive thrown explosives] doesn't work as well as expected in VATS mode as explained in that section of the link.
  
<span id="Issue: Unable to draw weapons, fire, or crouch"></span>
+
:*Solution-2: [http://www.nexusmods.com/newvegas/mods/40040/? Project Nevada] has an option to have the distance thrown based on your Strength (STR) instead of the default of "explosives" skill, in addition to using a "hotkey" to combine the selection and throw.

* Cause: Removal of all "tumbleweeds" from the game.  The first "tumbleweed" seen upon exiting Doc Mitchell's house after creating a character is scripted.  It's absence (i.e. a mod to remove all tumbleweeds also removes that script event) breaks the game.
 
  
* Solution:
+
:* Solution-3: There are also two other "grenade key" mods that are intended to make "grenade" (explosive) throwing easier:
** Temporary: Move to somewhere you know you should be able to use all those functions, open the in-game console (<~> key), and enter "EnablePlayerControls" (without the quotes) and hit <Enter>.
+
::* [http://www.nexusmods.com/newvegas/mods/38808/? Grenade Hotkey] by vivanto
** Permanent: Uninstall any mods that remove all tumbleweeds before creating a new character. Often this functionality is incorporated into "performance" mods, so if it isn't mentioned in the description some testing may be required. However, once the character has stepped outside of Doc Mitchell's so the scripted "tumbleweed" event occurs, they may be installed.

=== Issue: WMM '''The Weapon Mod Menu''' will not let me add a weapon mod in game ===
+
<span id="Issue: How to determine what keystrokes are being passed"></span>
* Cause: There are a number of unspoken assumptions by [http://www.nexusmods.com/newvegas/mods/44515/? The Weapon Mod Menu (WMM)] that, when verified/resolved, are the usual solutions.
 
  
:* Solution-1: You are trying to "modify" the ''currently equipped weapon'' when you hit the "x" key.
+
=== Issue - How to determine what keystrokes are being passed ===
 +
Sometimes "strange things happen" when you press a key and you wonder just what keystrokes were being sent.
  
:* Solution-2: You have a "weapon mod" that is appropriate for that specific weaponMost "weapon mods" only apply to very specific weapons.  There are (to the best of the collective knowledge) none that apply to ALL weaponsSo you have to check the name of the mod very carefully as the differences in the names are subtle.  The easiest way to determine the correct mod for a weapon in game is at the "green vending machines" provided by the additional mod [http://www.nexusmods.com/newvegas/mods/39651/? Weapon Mods Expanded (WMX)], which are generally found at all the "Gun Runners Arsenal" (GRA) storefronts.

This is a built-in game Main Menu setting, under: "Settings | Game Play | True Iron Sights [ON | OFF]"It is also accessible from the "Pause Menu" screen during a game session.  It is only visibly in effect in FPV.

* Solution-2: It can get complicatedRead this [http://wiki.nexusmods.com/index.php/HUD-UI-Menu_issues HUD-UI-Menu issues] wiki article.

: when you click using the (default) Right-Mouse button (aka "<RClick>") as if "blocking with a melee weapon" or "zooming in on the target with a scoped weapon".
 
  
Without the "True Iron Sights" setting to ON, the same "weapon centered in the screen" view is displayed, but the "rear sight" on the weapon is lower down and you cannot "truly" align the front and rear sights.  You use the "crosshair" instead.

+
=== Issue - MOUSE - not working after fast travel ===
=== Issue - Aiming - 1st Person View ''aka FPV'' is off center ===
+
* Cause: Unknown
The situation is a bit more complex than it appears on the surface.  Apparent weapon position is determined by the animation files.  It is also tied in with whether or not you use the game's "Auto Aim" feature, which is active by defaultIn addition there are various "Field of View" (FOV) settings the game switches between under certain circumstances, which affect what is visible of the scene.
+
:* Solution-1a: After "fast travel", enter the Pipboy "map" tab (see [[#Issue - MouseMisbehaves|Issue - Mouse Misbehaves]] for hotkeys), move the mouse cursor around a bit and then "<Right-Click>" on the map to enter into the "marker placement" menu to see if it is working againIt may take more than one attempt at wiggling the mouse cursor around, but once it responds to the mouse click it should work until the next time you "fast travel".
  
* Cause-1: This is controlled by a single variable: "fFirstPersonHandFollowMult". The default value is ".85", so this was a deliberate design decision to impose some inaccuracy by the developers, as a value of "1.0" is "dead center" of the aiming point.
+
:* Solution-1b: Rename the "Fallout.INI" and "FalloutPrefs.ini" files located in the "C:\Users\<UserAccountName>\Documents\My Games\FalloutNV" folder to some different name.  (Just adding a different extension such as ".org" works.)  Then use the game "FalloutNVLauncher.exe" program to cause them to be rebuiltRefer to the backed up original version files for your previous changes.
:* Solution-1a: The mod [http://www.nexusmods.com/newvegas/mods/55709/? Gun Follows Crosshairs in First Person] by '''Grasscid''' applies this fix.
 
:: Note the mod [http://www.nexusmods.com/newvegas/mods/35781/? First Person Gun No Follow] by '''Azrael Dark''' combines nicely with "Gun Follows" so the gun doesn't follow the cross-hairs up out of the "neutral carry position" until you actually fire.
 
:* Solution-1b: Set "fFirstPersonHandFollowMult" to "1.0"(Some other mods use this setting as well, so conflicts are possible.)
 
  
* Cause-2: Your problem might be a result of changing the "Field of View" (FOV).
+
<span id="Issue - MouseSensitivity"></span>
<blockquote>
 
From [http://www.tweakguides.com/Fallout3_8.html TweakGuides]:
 
: fDefaultFOV=75.0000 - Shows the default Field of View in degrees for the game, which is 75 degrees. Changing the Field of View using this variable doesn't seem to work properly as it is not applied when the game starts, so instead you will need to use the FOV console command (See Console Commands section) each time you start them game to set a different field of view.
 
  
: Update: It has been discovered that by inserting the line fDefaultWorldFOV=75.0 at the bottom of the Display section of the Fallout.ini file, and assigning it a value equal to the FOV you want, you can now permanently change the default Field of View in the game. Remember however that if you change the default FOV, you may also need to change the FOV for other screen elements - see the fRenderedTerminalFOV and fPipboy1stPersonFOV commands below. Note also that you can alter the fDefault1stPersonFOV=55.0000 value to alter how much of your body/weapon is shown in front of you (Fallout.ini).

Monitor is set to a higher than 1920x1080 resolution.
  
:* Solution-2a: [http://www.nexusmods.com/newvegas/mods/55085/? FOV Slider] by '''Roy Batty''' is a simple mod that adds an MCM menu that allows for adjusting the Fields of View for all of the game's camera viewsLook into "Weapon FOV scale" (to compensate for larger or smaller Player Fields of View and their affect on aim speed).
+
* Cause: FNV was designed for monitor resolutions common prior to 2010. "In 2010, 27-inch LCD monitors with the 2560 × 1440-pixel resolution were released by multiple manufacturers including Apple." - [https://en.wikipedia.org/wiki/Display_resolution Wikipedia on "Display resolution"].  "High Definition" (1920x1080, 16:9 aspect ratio) "FHD standard" was generally considered "high end" for gaming.  Newer monitors may have a higher default resolution.
  
:* Solution-2b: Other than adjusting the various FOV settings, try tweaking the following default values (which set the camera position relative to the head node in FPV) in the INIs [General] section:
+
:* Solution: Use a lower, more standard (in 2010) display resolution.  (Note the LED/Plasma monitors have a default resolution according to the screen size and "aspect ratio".  Lower resolutions may not fill the screen, resulting in "black borders" (e.g. "letterbox style").  "Windowed mode" may be a way around this visual problem.)  See the Wikipedia article quoted above for more on the subject, including a table of "resolution standards".
*: Make backups of the INIs before changing them.

=== Issue - Aiming - 3rd Person View ''aka TPV'' is off center ===
+
:* Solution: Edit the "Items | Weapon" entry with GECK so the first and second "Mod Info" tab slots under "Game Effects" are not emptyTypically this will mean moving the second and third slot entries up by oneBe sure to make the plugin containing the Weapon in question the "active" one, as that is the plugin that will get savedNote this edit will only work if there are already weapon mods available for that weapon.  Adding weapon mods that do not already exist is a more involved "customization" process.
* Cause: This is a more complex issue than aiming in 1st Person View (FPV).  The player is always viewing the action from the perspective of the camera.  The camera location is independent of the character's eyes, and from the weapon.  It is always "center of the screen".  In FPV, it is positioned to simulate the eye view of the character.  In 3rd Person View (TPV), the camera (and you) are not looking from the perspective of either the character or weaponInstead the camera is positioned behind and off to the side so the back of the character and more of the scene to the opposite side of the character is in view.  This camera setting is not generally adjustable, though there are mods that help.  The cross-hair is positioned in the center of the screenIt is not accurately aligned with the character's eyes or the weapon.  The "Field of View" (FOV) controls how much of the cell scene is visible.  This is adjustable and there are actually a number of inter-related FOV settings.
 
: Please see the [[#Issue: Aiming - Disable Auto Aim or not?|Issue: Aiming - Disable Auto Aim or not?]] section first to understand the role of Auto Aim on the problem.  As pointed out there, weapon animations are not aligned consistently the same.  In TPV, if Auto Aim is disabled there is no expectation that the alignment of the weapon is with the cross-hairAs the camera position is behind and offset to the right (by default) from the center of the body so you are looking more or less along the angle of the weapon towards the cross-hair, but you can't even expect the cross-hair to be aligned with the position of the body facing either.
 
  
: It is important to understand: the game is not designed for accuracy while shooting in TPV.  You are in essence always "shooting from the hip", while situational modifiers ("iron sights", crouching, weapon skill, etc.) affect the "spread" inherent in the weapon.  (See [http://geck.bethsoft.com/index.php?title=Gun_Spread_Formula GECK: Gun Spread Formula].)  If you need accuracy, then by design you need to be in FPV (which is why the game switches you to that mode ''when you use certain weapons or a "Scope"'' and have "True Iron Sights" enabled).  Not all weapons have "Iron Sights" (i.e. some energy weapons) and some "Power Armor" mods are known to "break/replace" the vanilla "True Iron Sights" functionality.  For accuracy, you want a smaller "fOverShoulderFOV" value to more closely align the center of the screen with the cross-hair.

=== Issue - WMM - '''The Weapon Mod Menu''' will not let me add a weapon mod in game ===
=== Issue - Aiming - Disable Auto Aim or not ===
+
* Cause: There are a number of unspoken assumptions by [http://www.nexusmods.com/newvegas/mods/44515/? The Weapon Mod Menu (WMM)] that, when verified/resolved, are the usual solutions.
* Cause: In Fallout 3 and New Vegas bullets can actually curve or shoot in a direction they shouldn't based on a dice roll (on top of the normal bullet spread).
 
: If we completely remove the Auto Aim features, the game fires your bullets from your weapon parallel to the 3D model (like it should be physically). The only issue is that every weapon is somehow differently aligned: the .44 Magnum is slightly pointing under the cross-hair, the Hunting Rifle is pointing to its right, etc ..  So without Auto Aim enabled, the cross-hair is not really where you are aiming anymore and it's different for each weapon.
 
: Basically the Auto Aim feature redirects your bullets toward the center of the screen.  This would be a great feature if it wasn't also used in combat as a targetting aid.  When your cross-hair is near the bounding box of an enemy's limb, Auto Aim instead shifts the bullets towards the nearest limb.  
 
  
:* Solution-1: [http://www.nexusmods.com/newvegas/mods/34723/? No Auto Aim] by '''EddieV223'''.  Rather than completely disabling Auto Aim, this mod uses some settings with values so small the effect is negligible.  Uses the following values (default = FalloutNV):

:* Solution-2: You have a "weapon mod" that is appropriate for that specific weapon.  Most "weapon mods" only apply to very specific weapons.  There are (to the best of the collective knowledge) none that apply to ALL weapons.  So you have to check the name of the mod very carefully as the differences in the names are subtle.  The easiest way to determine the correct mod for a weapon in game is at the "green vending machines" provided by the additional mod [http://www.nexusmods.com/newvegas/mods/39651/?

=== Issue - Aiming - Full-Auto Iron Sights animation jump ===
 
With "full auto" weapons, when aiming down the "iron sights" in 1st person and firing (even with "JIP Select Fire" set to single shot) the whole weapon seems to jump down so that the iron sights are below the actual aim point. When you stop firing it returns to normal.
 
  
: Files that modify "iron sight" firing animations always have the word "attack" in them, and end with "is" (for "iron sight")They begin with the number of hands holding the weapon (1h/2h), followed by the general weapon type ("P"istol, "A"utomatic, "R"ifle, "M"elee, etc.), which combined make up the "weapon category".  Automatic weapons all use one attack animation in their category: '''1hpattackloopis''' ("OneHandPistol" animation type in '''GECK''' or "Pistol - Ballistic" in '''FNVEdit'''); '''2haattackloopis''' ("TwoHandAutomatic" or "Rifle - Automatic"); and '''2hrattackloopis''' ("TwoHandRifle" or "Rifle - Ballistic"). Other "iron sight" weapons have their attacks marked with a number ('''2hrattack''3''is''' for example).

:* Solution-5: If none of the above are the problem, see if you can find anything in the "fallout_nv_error.log" file(See [[#Checklist|Checklist item #4]].)

* Cause: This weapon has an unfortunate (seemingly hard-coded) bug that means that any weapon mods applied to it will not be visible on the weapon.
  
=== Issue - Aiming - Weapon stays centered after releasing RMB ===
+
:* Solution: [http://www.nexusmods.com/newvegas/mods/39651 Weapon Mods Expanded (WMX)] detects that you have equipped the 'Weathered 10mm Pistol'.  The WMX menu (in the Pip-boy "Inventory" screen for the selected weapon) allows you to swap the defective original Weathered 10mm Pistol for a fully-functional duplicate of it. Doing so will effectively erase any weapon mods already applied to the weapon, so it is recommended to remove them first using [http://www.nexusmods.com/newvegas/mods/44515 The Weapon Mod Menu (WMM)]When you are ready to proceed, select the 'Swap Weapon' button. Select 'Cancel' if you are not ready to proceed (this menu will appear again when you next equip the bugged Weathered 10mm Pistol).
Basically: when you fire your weapon in TPV and press the (default) "Right Mouse Button (RMB)" (switching to FPV "scope" or "iron sights" aiming) and IMMEDIATELY let go of the RMB, the weapon stays centered for a second or so before it goes back to normalThis DOES NOT happen if you fire and hold RMB/Aim for those 1-2 seconds; it's almost as if the weapon is stuck in it's FPV firing position for a second or so every time you fire.  The camera zooms back out, but nothing else.
 
  
* Cause: This is a bug in some animations.  It is particularly noticeable with the "plasma rifle".
+
<span id="Issue - ZoomControls"></span>
:* Solution: Try an alternate source for the animation in question, and replace the vanilla ".kf" file.  Search the Nexus on the keyword "animation".  (There is also the mod [http://www.nexusmods.com/newvegas/mods/64339 Asurah Reanimation Pack] which will not get picked up by that keyword search.)  The mod [http://www.nexusmods.com/newvegas/mods/57561 Animation Resources] by '''Fallout2AM''' includes some, as well as a "AnimTool (AnT)" which allows you to invoke an animation after you choose it from a menu, on you or on a target (NPC or Creature) for testing.

<span id="Issue: Animation Clipping"></span>
+
=== Issue - ZOOM controls ===
=== Issue - Animation Clipping ===
+
Symptoms: Suddenly vision "zoom" features (such as "scoped weapons" and dialog "close-in to observe the speaker's face") and related manual controls are no longer working.
A common problem is "clipping" of the hand/fingers gripping a weapon while aiming or reloading.  Sometimes this appears as a gap between the hand and the weapon; sometimes as the weapon cutting into the hand.
 
  
* Cause-1: IF you are using combinations of mesh/texture and animation replacements, or various "post processor" packages such as "ENB", "Reshade/SweetFX", or "NewVegasReloaded/NVGE" then there may be conflicts just as with other mods.
+
* Cause: Likely a "Field of View (FoV)" setting or conflict.
:* Solution-1: Engage in [[# Mod_Conflict_Isolation|Mod Conflict Isolation]] to identify where the conflicts reside. Identify a consistent, readily determined example of the conflict. In  general, removing the most sweeping, broadly affecting "overhaul" addition first will be more efficient. It may even be necessary start from a bare-bones vanilla load order without any enhancements of any kind to determine the issue does not occur without any modifications. Then, gradually add and test.
+
:* Solution: Check FOV related setting in recently added mod INI files, such as (purely for example) "[https://www.nexusmods.com/newvegas/mods/65525 New Vegas Reloaded]" and "[https://www.nexusmods.com/newvegas/mods/55085 FOV Slider]", or enhanced configuration mod tools like [https://www.nexusmods.com/newvegas/mods/66347 lStewieAl's Tweaks].
  
* Cause-2: It's simply how the game handles weapon animations.  Weapon animation is shared between weapons of the same type (e.g "two handed weapons"). For example, both the "Hunting rifle" and the "Varmint rifle" use the same animation set, based upon the vanilla meshes. Some weapon mesh used by a given mod might be thicker or thinner, resulting in clipping.
+
<span id="Solutions to "Garden of Eden Construction Kit" (G.E.C.K.) problems"></span>
:* Solution-2: Not much can be done about it.  As most of the time these are "transient" temporary issues, it's best to just ignore them.  If it really bothers you, then you will have to give up whichever mod is providing the altered mesh causing the clipping. 
 
:: Note that mods considered purely one thing or another (such as "texture replacers") still might include their own meshes. Every mesh has embedded in it the path to the texture file it uses. If the mod uses a unique folder structure, then it HAS to have altered the mesh as well in order to find the correct textures. Case in point: version 2.x of [http://www.nexusmods.com/newvegas/mods/38285 Weapon Retexture Project (WRP)] by '''millenia'''.  Version 1 used a vanilla folder structure; version 2 has a unique one making it incompatible with some other popular mods (e.g. '''WMX''') and animation replacements.  Always check both the general mod description and that of the individual files.

Symptoms: When worn, the Authority Glasses don't "sit right"; as in dangle off the face incorrectly hanging down the side as if from one ear.

+
== Solutions to Graphics problems ==
:* Solution:  Let YUP overwrite those mods (somewhat difficult with just the "load order" as YUP should be loaded early/"low numbered" in the sequence) or resolve the conflict with a "Bashed/Merge Patch" file.  Please see the '[[FNV_General_Mod_Use_Advice#Third_Rule:_The_Rule_of_One Third Rule:|The Rule of One]]' and '[[FNV_General_Mod_Use_Advice#Merge_Patch_File|Merge Patch File]]' sections of the wiki "[[FNV_General_Mod_Use_Advice|FNV General Mod Use Advice]]" article.  When in doubt, create a "Merge Patch" file for your overall "load order" anyway.

<span id="Issue: Aiming - 1st Person View (FPV) is off center"></span>
=== Issue - Blood-Gore-Limb Explosions and Dismemberment ===
+
=== Issue - Aiming - 1st Person View ''aka FPV'' is off center ===
The Fallout series is known for being "bloody" and "gory" with dismembered limbs, exploding heads, and chunks of viscera ("gore globs") and splashes of blood lying aboutThe game does have a generally undocumented setting to turn ALL the blood and gore off, which is apparently enabled by default in the German regional "no gore" version; but no finer control over the chances of such occurring when sufficient damage is applied.
+
The situation is a bit more complex than it appears on the surfaceApparent weapon position is determined by the animation files. It is also tied in with whether or not you use the game's "Auto Aim" feature, which is active by defaultIn addition there are various "Field of View" (FOV) settings the game switches between under certain circumstances, which affect what is visible of the scene.
* Cause: This is by design.  The points of dismemberment are defined in the mesh file as "animation nodes", and are called "meat caps"These "meat caps" are the visible stumps remaining on each end when the limb is dismembered or exploded.  A detached limb can then be further dismembered into "gore chunks".
 
:* Solution-1: To completely disable all gore and blood effects:
 
:: Open Fallout "INI" files (located in both the game root folder and the "Users" folder).
 
:: Add under the "[General]" section of all three:
 
:: <pre>bDisableALLGore=1</pre>
 
:: Save the file.
 
  
:* Solution-2: To adjust the chance of Limb Dismemberment and Explosion in finer detail, the mod [http://rd.nexusmods.com/newvegas/mods/59147 Ragdolls] by '''MadAce''', under it's '''MCM''' menu has settings affecting:
+
* Cause-1: This is controlled by a single variable: "fFirstPersonHandFollowMult".  The default value is ".85", so this was a deliberate design decision to impose some inaccuracy by the developers, as a value of "1.0" is "dead center" of the aiming point.
::* "Limb Explosion chance"
+
:* Solution-1a: The mod [http://www.nexusmods.com/newvegas/mods/55709/? Gun Follows Crosshairs in First Person] by '''Grasscid''' applies this fix.
::* "Limb Dismemberment Chance"
+
:: Note the mod [http://www.nexusmods.com/newvegas/mods/35781/? First Person Gun No Follow] by '''Azrael Dark''' combines nicely with "Gun Follows" so the gun doesn't follow the cross-hairs up out of the "neutral carry position" until you actually fire.
::* "Limb Dismemberment Chance"
+
:* Solution-1b: Set "fFirstPersonHandFollowMult" to "1.0".  (Some other mods use this setting as well, so conflicts are possible.)
::* "Explosion Strength"
 
::* "Projectile Strength"

<span id="Issue: Body Replacer - Big Head / Hair bug"></span>
+
* Cause-2: Your problem might be a result of changing the "Field of View" (FOV).
 +
<blockquote>
 +
From [http://www.tweakguides.com/Fallout3_8.html TweakGuides]:
 +
: fDefaultFOV=75.0000 - Shows the default Field of View in degrees for the game, which is 75 degrees. Changing the Field of View using this variable doesn't seem to work properly as it is not applied when the game starts, so instead you will need to use the FOV console command (See Console Commands section) each time you start them game to set a different field of view.
  
=== Issue - Body Replacer - Big Head or Hair bug ===
+
: Update: It has been discovered that by inserting the line fDefaultWorldFOV=75.0 at the bottom of the Display section of the Fallout.ini file, and assigning it a value equal to the FOV you want, you can now permanently change the default Field of View in the game. Remember however that if you change the default FOV, you may also need to change the FOV for other screen elements - see the fRenderedTerminalFOV and fPipboy1stPersonFOV commands below. Note also that you can alter the fDefault1stPersonFOV=55.0000 value to alter how much of your body/weapon is shown in front of you (Fallout.ini).
When you unpack the BSA's to do modding for Fallout NV, the Actor's grow abnormally large foreheads which make people look half-bald, and make it so hair sticks out of hats, or hats become embedded in the heads.
+
</blockquote>
  
Cause: EGM files don't work outside of BSA archives in '''Fallout New Vegas'''.
+
:* Solution-2a: [http://www.nexusmods.com/newvegas/mods/55085/? FOV Slider] by '''Roy Batty''' is a simple mod that adds an MCM menu that allows for adjusting the Fields of View for all of the game's camera views. Look into "Weapon FOV scale" (to compensate for larger or smaller Player Fields of View and their affect on aim speed).
: Meaning, you have to have the head / hairs / character files for the mod in a BSA file (named after the mod).  The problem occurs when any of the files (even original vanilla ones) are "loose" outside of a BSA.  It's a quirk of the game engine.
 
:* Solution: Package the modded loose files into a BSA when done.
 
:: The rules for naming a BSA are simple: the first significant portion (enough to distinguish it from any other similar but different mod name) must match that of the mod plugin ESP file, and have the ".BSA" extension.  There can be more than one such BSA plugin, but usually this "matching significant portion of the ESP filename" is up to any embedded space (e.g. "Fallout - Textures.bsa").  It must be packaged as a "Bethesda Software Archive" (BSA) using a tool like "[http://www.nexusmods.com/newvegas/mods/64745 BSArch]", and containing the same folder paths as the loose files used by the mod in question.

* Cause: Install failures, usually from not understanding what is involved.
+
* Cause-3: A surprising number of vanilla weapons have misaligned meshes between the projectile nodes and the cross-hair.
:* Solution: This is a general guide to what is involved in replacing the vanilla body of one gender with a "Custom Race" one for the Player Character Only. Mods for NPCs are separate.  There are separate mods for Males and Females or other Custom Races. Refer to the specific body mod install instructions for specific details appropriate to that modBut understanding what is involved will make it easier to understand those options.   For another detailed explanation, see the [http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice#Body_Replacement_Basics Body Replacement Basics] section of the "FNV General Mod USE Advice" article.
+
:* Solution-3: The [http://www.nexusmods.com/newvegas/mods/65052 Weapon Mesh Improvement Mod (WMIM)] by '''Roy Batty''' is an on-going effort to fix the vanilla weapons wholesale.  Similar issues with mod added weapons have to be taken up with their respective authors in comments on those mod download pages.  There are various individual mods to be found by using the Nexus "search" function on the term "iron sights".
 +
::<span style="color: red;background-color:#fff5f5;">NOTE: While '''WMIM''' is "meshes" and [http://www.nexusmods.com/newvegas/mods/38285 Weapon Retexture Project (WRP)] by '''Millenia''' is "textures", the latter includes modified meshes that are required for his textures to display properly with their own sub-folder, so it's incompatible with any other mods that adjust vanilla weapon meshes. (Notably most "Nifskope Weapon" mods and '''WMIM''''''WRP v1.95''' from 2012 uses vanilla folder paths and is somewhat more compatible.)  The [http://www.nexusmods.com/newvegas/mods/38927 Rifle 1st Person Accuracy Fix] mod by '''joefoxx082''' is an alternative solution to the accuracy issue, though obviously not as comprehensive as '''WMIM'''. As is often the case, you may have to give up one mod or the other.</span>
  
:: Replacing the vanilla body involves two different sets of files: "meshes" and "textures", which usually come as separate mods.  Mods labelled "body type" are actually "meshes" that have a different shape (proportions) in some regards to those used for the vanilla body. They are generally going to be found in the Nexus site [http://www.nexusmods.com/newvegas/mods/searchresults/?src_cat=66 New Vegas Models and Textures] category.
 
  
:: Body replacement only affects the "unclothed" body. "Clothing" and "armor" (collectively: "garments") have their own "body shape", which is independent of that of the underlying body. They do not "warp around" or "conform to" the underlying body; they completely replace it.  If you have body replacement type "A" and clothing/armor for body type "B", what you see is type "B".  So the "nude" body type does not appear at all; even the "bare skin" elements are part of the garment.  ALL "garment" mods are based around some body type (assume "vanilla" if not specified).  FNV does not have separate "slots" for different parts of the body: only distinguishing between the head, hands, and the remainder of the body (misleadingly called "upper body slot" (there is no "lower body" nor "legs" slot). Further on the consequences of this below.
+
<span id="Issue: Aiming - 3rd Person View (TPV) is off center"></span>
  
:: The vanilla body "texture" has underwear included, so it is not removableCustom body textures may have both a "nude" option and an "underwear" option textureThese are "all-or-nothing" choices: everyone is nude underneath their armor and clothing, or everyone wears underwearSelect a custom body ''texture'' mod that is designed to be compatible with your custom body type (i.e. the ''mesh'') modOtherwise you may have apparent "black bands" around the groin area or huge scars on the breasts because the ''vanilla texture'' (used by default) doesn't fit correctly to the adjusted body mesh.  There is now at least one "nude body" texture mod for vanilla meshes: ''Simple Vanilla Nude Body Replacers'' by '''Jokerine''' (linked below under "NPC overhauls".  Toggling "ArchiveInvalidation" off-and-then-on again as with other texture replacements may be necessary.
+
=== Issue - Aiming - 3rd Person View ''aka TPV'' is off center ===
 +
* Cause: This is a more complex issue than aiming in 1st Person View (FPV).  The player is always viewing the action from the perspective of the camera.  The camera location is independent of the character's eyes, and from the weapon.  It is always "center of the screen".  In FPV, it is positioned to simulate the eye view of the character.  In 3rd Person View (TPV), the camera (and you) are not looking from the perspective of either the character or weaponInstead the camera is positioned behind and off to the side so the back of the character and more of the scene to the opposite side of the character is in viewThis camera setting is not generally adjustable, though there are mods that help.  The cross-hair is positioned in the center of the screenIt is not accurately aligned with the character's eyes or the weaponThe "Field of View" (FOV) controls how much of the cell scene is visible.  This is adjustable and there are actually a number of inter-related FOV settings.
 +
: Please see the [[#Issue: Aiming - Disable Auto Aim or not?|Issue: Aiming - Disable Auto Aim or not?]] section first to understand the role of Auto Aim on the problem.  As pointed out there, weapon animations are not aligned consistently the same.  In TPV, if Auto Aim is disabled there is no expectation that the alignment of the weapon is with the cross-hair.  As the camera position is behind and offset to the right (by default) from the center of the body so you are looking more or less along the angle of the weapon towards the cross-hair, but you can't even expect the cross-hair to be aligned with the position of the body facing either.
  
:: As a consequence of these custom meshes, vanilla clothing and armor will have "clipping" issues where body parts show through or don't seem to "fit" correctly leaving gaps or seamsSome "clipping" is minor, but often it is major enough that you have to also install mods for clothing and armor that are made specifically for that body type.  Note that armor usually has it's own "body mesh" included, avoiding this clipping.  (  This is not true for "accessories" that go on sub-sets of the body: such as gloves, bracers, and clothing.) This means armor ignores the underlying "body" shape and instead that you can choose among those using the same texture UVmapping based upon the same base model (i.e. Type 6M, Type 6, Type 3M, Type 3F, and Type 3)As a consequence, your Type 6 naked body can "wear" a Type 3 armor, but will appear to be Type 3 in proportions until it is taken off.
+
: It is important to understand: the game is not designed for accuracy while shooting in TPV.  You are in essence always "shooting from the hip", while situational modifiers ("iron sights", crouching, weapon skill, etc.) affect the "spread" inherent in the weapon.  (See [http://geck.bethsoft.com/index.php?title=Gun_Spread_Formula GECK: Gun Spread Formula].) If you need accuracy, then by design you need to be in FPV (which is why the game switches you to that mode ''when you use certain weapons or a "Scope"'' and have "True Iron Sights" enabled)Not all weapons have "Iron Sights" (i.e. some energy weapons) and some "Power Armor" mods are known to "break/replace" the vanilla "True Iron Sights" functionalityFor accuracy, you want a smaller "fOverShoulderFOV" value to more closely align the center of the screen with the cross-hair.
  
:: "B-n-B" or "Bouncing Breasts and/or Butts" mods are meshes based upon a different "armature" or "skeleton" rigged with added "bones" (i.e. "breast bones") and weights to support the "bouncing" parts.  (These different bones and weighings are also the case with some "Havok" and "Power Armor" mods.)  They will either provide or tell you to use a specific "skeleton" in order to work correctly.  Without that customized skeleton, the "bouncing" parts will not bounce and may appear "deformed" (i.e. stretching out to the horizon) or otherwise appear "weird"There is only one skeleton used by each race in the game, so it will not adversely affect any "non-bouncing" meshes which will just ignore the added bones they don't know about.  As a consequence, in order to see the "bouncing" effect in clothing and armors, you may need to install mods with those "bouncing" features enabled.  Sometimes special animations for certain actions (i.e. walking, sneaking, jumping, swimming, dancing) are also available.  Not all mods can use the same specialized skeleton, so check the description/documentation for each carefully.  This "skeleton" choice can easily limit your options.  There are three "universal compatibility skeleton" mods for FNV on '''Nexus''' designed to overcome this compatibility problem:
+
:* Solution-1: Use a mod that allows you to adjust the left to right offset of the camera positionEither of works well combined with Solution-2 options:

::: Read their descriptions carefully.
 
  
:: Because the head is separate from the body, that means it too can have custom versions of it's mesh and textures. In all other regards it is similar to but independent of the body. As the head (hair and face) is a separate component from the rest of the body, custom meshes often have a problem with a visible "seam" where the head mesh joins with the body mesh. It is just a fact of life you will have to live with; nothing the mod creators can completely eliminate. There are "seam concealer" mods that provide necklaces and similar to hide this seam.
+

 +
:: Those interesting in fighting primarily while in TPV should experiment with "fOverShoulderFOV" and "Iron Sight FOV Zoom Time".
  
:: Some features, such as scars and tattoos, are part of the texture and not a separate addition.  Others have to use specific [http://geck.bethsoft.com/index.php?title=Race body part slots], which are broken down into "Body Data", "Face Data", and "FaceGen Race".  Only one mesh can be assigned to each body part.  For instance, "Face Data" has only "Eye colors" and "Hair styles".  Which in turn means you can have "hair" or a "hat/helmet" but not both. If there is hair showing under a hat or helmet, it is part of that "hat" mesh. FNV does not have a separate slot for "facial hair" (i.e. beards, mustaches, "mutton chops", etc.)Mod authors have to cannibalize the use of a different slot for the purpose, or make the facial hair part of the texture itself.
+
<span id="Issue: Aiming - Disable Auto Aim or not?"></span>
 +
=== Issue - Aiming - Disable Auto Aim or not ===
 +
* Cause: In Fallout 3 and New Vegas bullets can actually curve or shoot in a direction they shouldn't based on a dice roll (on top of the normal bullet spread).
 +
: If we completely remove the Auto Aim features, the game fires your bullets from your weapon parallel to the 3D model (like it should be physically). The only issue is that every weapon is somehow differently aligned: the .44 Magnum is slightly pointing under the cross-hair, the Hunting Rifle is pointing to its right, etc ..  So without Auto Aim enabled, the cross-hair is not really where you are aiming anymore and it's different for each weapon.

: Basically the Auto Aim feature redirects your bullets toward the center of the screen.  This would be a great feature if it wasn't also used in combat as a targetting aid.  When your cross-hair is near the bounding box of an enemy's limb, Auto Aim instead shifts the bullets towards the nearest limb.

=== Issue - Aiming - Full-Auto Iron Sights animation jump ===
 +
With "full auto" weapons, when aiming down the "iron sights" in 1st person and firing (even with "JIP Select Fire" set to single shot) the whole weapon seems to jump down so that the iron sights are below the actual aim point. When you stop firing it returns to normal.
 +
 
 +
: Files that modify "iron sight" firing animations always have the word "attack" in them, and end with "is" (for "iron sight")They begin with the number of hands holding the weapon (1h/2h), followed by the general weapon type ("P"istol, "A"utomatic, "R"ifle, "M"elee, etc.), which combined make up the "weapon category".  Automatic weapons all use one attack animation in their category: '''1hpattackloopis''' ("OneHandPistol" animation type in '''GECK''' or "Pistol - Ballistic" in [http://www.nexusmods.com/newvegas/mods/34703/? FNVedit]); '''2haattackloopis''' ("TwoHandAutomatic" or "Rifle - Automatic"); and '''2hrattackloopis''' ("TwoHandRifle" or "Rifle - Ballistic"). Other "iron sight" weapons have their attacks marked with a number ('''2hrattack''3''is''' for example).
  
:: FAQs:<br>
+
: In order to know which animations cause problems, it would be beneficial to have '''FNVEdit''' installed, load all the mods affecting that weapon, and check which attack animation the weapon in question uses. Or if you use '''GECK''', you can discover this in the "Art & Sound" section of the weapon.

:: Q: What is the difference between Body Type 3 and Body Type 6M, etc?<br>
+
:* Solution-2: Mod [http://www.nexusmods.com/newvegas/mods/65052?tab=posts Weapon Mesh Improvement Mod]
:: A: It's a matter of personal preference in "shape": breast, hip and/or butt size.  All are potentially weighted differently ("bounce" effect).  Type 6 has an "apple bottom", Type 3 are thinner "waifs".  Apparently T3 originated in Fallout 3 along with Type V; Type 6 (another variant of Type 3) by '''Necroscope''' came along when NV came out, but has since been hidden by the author.  Type 6M (by '''Izumiko''') is a "rounder" modification of the basic Type 6 model.  Why do they have numbers? Your guess is as good as any. Any that have T3 in the name are derivatives of the original Dimonized Type 3 set from Fallout 3 (variants: Alice, Berry, Cali = A Cup, B Cup, C Cup).
+
: There are other "weapon animation" replacement mods as well that may perform better with a particular weaponNow you know enough to "pick and choose" which files to replace between mods.
:::* HD versions have more polygons, which place a heavier demand on the video memory.
 
:::* Hentai versions have puffy nipples and are based on T3F.
 
:::* It's best to use clothing and armor specific to the particular body type or they won't render properlyAnd it's not simple to "fix".
 
  
:: Q: Can Body Type6M (or T6, Type V/T5, T3BG, or T3M) can be used with textures for Body Type3?<br>
+
<span id="Issue: Aiming - Weapon stays centered after releasing RMB"></span>
:: A: Yes, if they have the same '''UVmapping''' (part of the texture "*.dds" file).  However, the dimensions of the armor will not change from the Type3 to the others.  The armor contains it's own body mesh.  (See the next question.)  The mod [http://www.nexusmods.com/newvegas/mods/67079 Wasteland Gals - Body Textures and Playable Races Type 3 4 6] is a retexture of type 3, 4 and 6 female bodies and faces that makes raiders, ghouls and old people playable.  (Note the caveats near the bottom of the description carefully.)
 
  
:: Q: What about clothing and armor compatibility between body types?<br>
+
=== Issue - Aiming - Weapon stays centered after releasing RMB ===
:: A: Compatibility is a problematic term to use in this case.  Generally, the only thing that is needed for the body types and associated armors to work together is for them to share the same '''UVmap'''.  Any mesh that shares a '''UVmap''' can also share textures.  And generally the ones that are variations on Type3 do.  There are more choices for Type3 bodies than any others.  Remember: the "garment" completely replaces the body supposedly underneath it.  You are seeing the shape of the garment mesh, not that of the naked body.
+
Basically: when you fire your weapon in TPV and press the (default) "Right Mouse Button (RMB)" (switching to FPV "scope" or "iron sights" aiming) and IMMEDIATELY let go of the RMB, the weapon stays centered for a second or so before it goes back to normal.  This DOES NOT happen if you fire and hold RMB/Aim for those 1-2 seconds; it's almost as if the weapon is stuck in it's FPV firing position for a second or so every time you fire.   The camera zooms back out, but nothing else.
::: "BnB" is a little more complicated.  Basically, in order to use BnB you have to have the skeleton.  So you can't just take an individual BnB outfit and have it work unless you've downloaded the skeleton from the main file.  The reason is because the outfit will have two reference bones (left breast and right breast) that aren't in the normal skeleton, and that causes glitches or crashesBut you can have the BnB stuff installed and still use other non-bounce outfits, because those outfits don't need the extra bones.
 
::: Now, if your idea of compatibility is for your character's body to stay the same size no matter the outfits, then you're generally out of luck.  For the time you're wearing an outfit, your body will be that size, for most things.  This is because virtually all major outfits include their own body meshes as part of the outfit.  The exception are accessory-type items like individual shirts or shorts or whatever.  Those are usually fitted to a particular body that is NOT included in the mesh file, and in this case if you're not using the right body then the clothing will clip badly.  As always, read the documentation carefully.
 
::: However, with that said, there was a tool called [http://kgtools.wordpress.com/clothing-converter/ KGTools Clothing Converter].  This would automatically convert Armor, Clothing, or Equipment from one body style to another!  Unfortunately the KGTools web site containing the downloads is no longer accessible.  Use the links [http://www.loverslab.com/topic/27557-new-clothing-body-style-converter-beta-v089f-10-26-2014/ on this site (adults 18+ only)] instead. The documentation is still available on the first link provided.
 
  
:: Q: Can I use a different body type for my companions (and NPCs) than for my character?<br>
+
* Cause: This is a bug in some animations.  It is particularly noticeable with the "plasma rifle".
:: A: Yes, as long as they have their own ''male/femaleupperbody.nif'' file.
+
:* Solution: Try an alternate source for the animation in question, and replace the vanilla ".kf" file.  Search the Nexus on the keyword "animation".  (There is also the mod [http://www.nexusmods.com/newvegas/mods/64339 Asurah Reanimation Pack] which will not get picked up by that keyword search.) The mod [http://www.nexusmods.com/newvegas/mods/57561 Animation Resources] by '''Fallout2AM''' includes some, as well as a "AnimTool (AnT)" which allows you to invoke an animation after you choose it from a menu, on you or on a target (NPC or Creature) for testing.
  
: In summary, you can expect to need "Body Type", "Body Texture", "Clothing and Armor", and possibly "Head", "Hair", and "Eyes" mods that are all compatible to work together.
+
<span id="Issue: Animation Clipping"></span>
 +
=== Issue - Animation Clipping ===
 +
A common problem is "clipping" of the hand/fingers gripping a weapon while aiming or reloading.  Sometimes this appears as a gap between the hand and the weapon; sometimes as the weapon cutting into the hand.
 +
 
 +
* Cause-1: IF you are using combinations of mesh/texture and animation replacements, or various "post processor" packages such as "ENB", "Reshade/SweetFX", or "NewVegasReloaded/NVGE" then there may be conflicts just as with other mods.
 +
:* Solution-1: Engage in [[# Mod_Conflict_Isolation|Mod Conflict Isolation]] to identify where the conflicts reside.  Identify a consistent, readily determined example of the conflict.  In  general, removing the most sweeping, broadly affecting "overhaul" addition first will be more efficient.  It may even be necessary start from a bare-bones vanilla load order without any enhancements of any kind to determine the issue does not occur without any modifications.  Then, gradually add and test.
 +
 
 +
* Cause-2: It's simply how the game handles weapon animations.  Weapon animation is shared between weapons of the same type (e.g "two handed weapons"). For example, both the "Hunting rifle" and the "Varmint rifle" use the same animation set, based upon the vanilla meshes. Some weapon mesh used by a given mod might be thicker or thinner, resulting in clipping.
 +
:* Solution-2: Not much can be done about it.  As most of the time these are "transient" temporary issues, it's best to just ignore them.  If it really bothers you, then you will have to give up whichever mod is providing the altered mesh causing the clipping. 
 +
:: Note that mods considered purely one thing or another (such as "texture replacers") still might include their own meshes. Every mesh has embedded in it the path to the texture file it uses.  If the mod uses a unique folder structure, then it HAS to have altered the mesh as well in order to find the correct textures.  Case in point: version 2.x of [http://www.nexusmods.com/newvegas/mods/38285 Weapon Retexture Project (WRP)] by '''millenia'''.  Version 1 used a vanilla folder structure; version 2 has a unique one making it incompatible with some other popular mods (e.g. '''WMX''') and animation replacements.  Always check both the general mod description and that of the individual files.
  
<span id="Issue: Body Replacer - Custom Hair, Eyes, Heads, and/or Races"></span>

<span id="Issue: AuthorityGlasses"></span>
 +
=== Issue - Authority Glasses worn weirdly ===
 +
Symptoms: When worn, the Authority Glasses don't "sit right"; as in dangle off the face incorrectly hanging down the side as if from one ear.
  
=== Issue - Body Replacer - Custom Hair-Eyes-Heads and-or Races ===
+
* Cause:  Conflict between "[http://www.nexusmods.com/newvegas/mods/51664/? Yukichigai Unofficial Patch - YUP]" and any mod that replaces the mesh for the Authority Glasses.
Problems getting custom heads or head elements (e.g. Hair and Eyes) to work correctly with a specific body replacement mod.
+
:* Solution:  Let YUP overwrite those mods (somewhat difficult with just the "load order" as YUP should be loaded early/"low numbered" in the sequence) or resolve the conflict with a "Bashed/Merge Patch" file. Please see the '[[FNV_General_Mod_Use_Advice#Third_Rule:_The_Rule_of_One Third Rule:|The Rule of One]]' and '[[FNV_General_Mod_Use_Advice#Merge_Patch_File|Merge Patch File]]' sections of the wiki "[[FNV_General_Mod_Use_Advice|FNV General Mod Use Advice]]" article. When in doubt, create a "Merge Patch" file for your overall "load order" anyway.
  
* Cause-1: As pointed out in [[#Issue:_Body_Replacer_-_Custom_Body_Types|Issue: Body Replacer - Custom Body Types]] you can't just assume every mod affecting the head will work with every other, or even with the body mod you have chosen.  They are not "mix-n-match".  For example, if it says it's for "Head03", then it won't work with the vanilla game heads.  The popular mod [http://www.nexusmods.com/newvegas/mods/44312/? Mojave Delight for Type3] by '''Glosshouse''' is for '''Type3''' bodies only, while [http://www.nexusmods.com/newvegas/mods/35878/? Beauty Pack PLUS -Project Mikoto- Hair - Eyes - Presets] by '''Matteius''' is not intended to work with any [[custom race]] body mods like '''Type3'''.  Read the description and installation instructions carefully to determine what the mod is designed to work with.  Most known issues are noted either on the description page or under the "comments" page.  Note that some require MANUAL installation.

There is a long standing issue with custom races, hair and eye incompatibility causing CTD. Be forewarned that you WILL experience CTD when using the Character Generator IF you do this:<br>

</blockquote>
 
: Once you have successfully changed eye color, then you can safely change to your custom hair style.  But any time later that you wish to change any of these features you must repeat the process: vanilla hair, custom eyes, custom hair.
 
:* Solution-1: Hair and Eyes are "slots" on the head.  This mean such mods are either replacement textures for the head model (either vanilla or some custom head), or have to edit the mesh and texture files to point to the mod's elements using the GECK.  The solution depends upon the mod.

* Cause-2: Unsuccessfully trying to switch between race or hair mods.  The character becoming invisible, getting stuck in the ground and unable to even use the console to toggle the "clipping" command (''TCL''), or unable to access the Pip-boy, usually happens if you uninstall/disable the race that your character is set to.  Trying to use the console command "''ShowRaceMenu''" here will probably crash the game.
+
[Decals]<br>
:* Solution-2: Instead reinstall and enable whatever mod contains the race you were playing, then use the console ''ShowRaceMenu'' command to switch to something else vanilla before removing it again.  Then perform a "Clean Save" as laid out in the 'Clean Saves' section of the wiki "FNV General Mod Use Advice" article before attempting to install a replacement.

<span id="Issue: Body Replacer - Custom Race skin mismatch"></span>
+
<span id="Issue: Blood, Gore, Limb Explosions & Dismemberment"></span>
 +
=== Issue - Blood-Gore-Limb Explosions and Dismemberment ===
 +
The Fallout series is known for being "bloody" and "gory" with dismembered limbs, exploding heads, and chunks of viscera ("gore globs") and splashes of blood lying about.  The game does have a generally undocumented setting to turn ALL the blood and gore off, which is apparently enabled by default in the German regional "no gore" version; but no finer control over the chances of such occurring when sufficient damage is applied.
 +
* Cause: This is by design.  The points of dismemberment are defined in the mesh file as "animation nodes", and are called "meat caps".  These "meat caps" are the visible stumps remaining on each end when the limb is dismembered or exploded.  A detached limb can then be further dismembered into "gore chunks".
 +
:* Solution-1: To completely disable all gore and blood effects:
 +
:: Open Fallout "INI" files (located in both the game root folder and the "Users" folder).
 +
:: Add under the "[General]" section of all three:
 +
:: <pre>bDisableALLGore=1</pre>
 +
:: Save the file.
  
=== Issue - Body Replacer - Custom Race skin mismatch ===
+
:* Solution-2: To adjust the chance of Limb Dismemberment and Explosion in finer detail, the mod  [http://rd.nexusmods.com/newvegas/mods/59147 Ragdolls] by '''MadAce''', under it's '''MCM''' menu has settings affecting:
This is most commonly seen as a difference between the skin color of the head and the body.  This is a "texture" problem.  Adjusting the tone sliders in the racemenu does not change anything.
+
::* "Limb Explosion chance"
* Cause: This generally occurs when the plugin is an ESP rather than an ESM file.
+
::* "Limb Dismemberment Chance"
:* Solution: Note that the Player and NPCs are distinct and what is a problem for one may not be for the other.
+
::* "Limb Dismemberment Chance"
:: A custom race defined in an ESP will work properly for the player, even though the head and body will be mismatched for NPCs.
+
::* "Explosion Strength"
:: Defining the NPC in an ESM is the only solution that works for everyone.
+
::* "Projectile Strength"
:: If you are using this on an NPC, make sure the NPC is defined in an ESM and not in an ESP. There are some tweaks to your INI files that can kinda fix it for ESP files, but they don't work for everyone.
+
:: which can be set all the way down to zero percent (pt).  Please note this does not distinguish between the damage inflicted by "projectile" and "energy" weapons.
::* In both the "Fallout.INI" and "FalloutPrefs.INI" files in the "C:\Users\<AccountName>\Documents\My Games\FalloutNV" folder, and the "Fallout_default.INI" in the game root folder, set:

">bLoadFaceGenHeadEGTFiles=1</div>
 
::* Toggling "ArchiveInvalidation" sometimes works, as does repeatedly reloading the save game again and toggling it until the head and body match skin tones.
 
  
:: It is also possible that the shader type and shader flags are set wrong in the race's body mesh. Skin parts need the shader type to be ''SHADER_SKIN'', and the ''SF_Specular'', ''SF_Skinned'', ''SF_FaceGen'', ''SF_Remappable_Textures'', and ''SF_ZBuffer_Test'' flags need to be set. You can check and modify these using '''NifSkope'''. If these are not set properly, then the custom race body and skin won't work properly for both NPCs and for the player, if the player uses that race.
+
<span id="Issue: BobbingNPCs"></span>
 +
=== Issue - Bobbing NPCs ===
 +
Symptoms: All NPCs start to bob up and down whenever looked at from close range. Zooming in on them causes it from any distance, even with a vanilla game.
  
:: Another thing to check is that the skin textures are all there and are all named properly. If the body texture for the race is named '''UpperBody.dds''', then the normal map needs to be named '''UpperBody_n.dds''' and the skin needs to be '''UpperBody_sk.dds''', and all of those files need to be in the same folder. You only define the base texture ('''UpperBody.dds''') for the race in the '''GECK''''. The '''GECK''' just assumes that the other files will be in the same place and will have the same name.
+
* Cause: Framerate higher than 60FPS. The more your framerate is above 60 fps, the more likely you'll see this problem.
 +
:* Solution-1a: Make sure that your in-game framerate is capped below 120 FPS. Use some FPS counter within the game to double check if it really is below 120.
 +
:* Solution-1b: There is a trade off between ''player foot dynamic placement'' efficiency and the absence of foot bouncing glitches for NPCs. It eliminates NPCs bouncing glitches almost entirely, but also makes ''player dynamic foot placement'' work slightly worse.
 +
:: Set these lines in either "FalloutPrefs.ini" or "FalloutCustom.ini" to the following:
 +
<div style="margin:0px 10px 10px 50px; border:1px solid #DAA520; color:#FF9933; background-color:#000000; padding:3px;">
 +
[FootIK]<br>
 +
fOnOffGain=0.01<br>
 +
bFootPlacementOn=0<br>
 +
fPelvisUpDownBias=0<br>
 +
fPelvisOffsetDamping=0<br>
 +
fOriginalGroundHeightMS=0
 +
</div>
 +
:* Solution-1c: Disable ''FootIK'' completely.
 +
<div style="margin:0px 10px 10px 50px; border:1px solid #DAA520; color:#FF9933; background-color:#000000; padding:3px;">
 +
[RagdollAnim]<br>
 +
bFootIK = 0
 +
</div>
  
:: And finally, keep in mind that whatever '''clothes''' or '''armor''' you use will have body parts defined, and those skin textures will show instead of whatever body you have defined in the '''GECK'''. In other words, if your character is wearing overalls and bare arms are visible, those bare arms are part of the overalls mesh and are not the bare arms from the race's body mesh. If the clothing wasn't created especially for your custom race, the bare skin parts of the outfits might not match the rest of your custom body type.

<span id="Issue: Body Replacer - Default/Vanilla"></span>
+
Cause: EGM files don't work outside of BSA archives in '''Fallout New Vegas'''.
=== Issue - Body Replacer - Default ''aka Vanilla'' ===
+
: Meaning, you have to have the head / hairs / character files for the mod in a BSA file (named after the mod).  The problem occurs when any of the files (even original vanilla ones) are "loose" outside of a BSA.  It's a quirk of the game engine.
No matter your opinion of the matter, one of the most common reasons for installing a "body replacer" is to enable a "nude body" when clothing and armor are removed(Since these are classified as "Adult" mods, you may need to change your Nexus Profile "Content Blocking" setting to access them.)  Some would prefer to not have to get into the complexities of resorting to "custom races" to get this feature.
+
:* Solution: Package the modded loose files into a BSA when done.
 +
:: The rules for naming a BSA are simple: the first significant portion (enough to distinguish it from any other similar but different mod name) must match that of the mod plugin ESP file, and have the ".BSA" extension.  There can be more than one such BSA plugin, but usually this "matching significant portion of the ESP filename" is up to any embedded space (e.g. "Fallout - Textures.bsa")It must be packaged as a "Bethesda Software Archive" (BSA) using a tool like "[http://www.nexusmods.com/newvegas/mods/64745 BSArch]", and containing the same folder paths as the loose files used by the mod in question.
 +
:: See also the other "Issue: Body Replacer -" entries under 'Solutions to Graphics problems' section in the wiki "[http://wiki.nexusmods.com/index.php/Fallout_NV_Mod_Conflict_Troubleshooting Fallout NV Mod Conflict Troubleshooting]" guide.
  
* Cause: The provided default (vanilla) bodies in the game have "underwear" as an integral part of the body texture.  This cannot be "removed" along with other clothing or armorThere are some mods which provide alternative "underwear", but these are also integrated into the texture.
+
<span id="Issue: Body Replacer - Custom Body Types"></span>
 +
=== Issue - Body Replacer - Custom Body Types ===
 +
Problems getting various custom body replacements, such as "Type 3" and "Type 6", to work correctly(Since most of these are classified as "Adult" mods, you may need to change your Nexus Profile "Content Blocking" setting to access them.)
  
:* Solution: The mod "Simple Vanilla Nude Body Replacers by Ghostwalker71 and Jokerine" is a simple mesh and texture replacer that gives the default bodies anatomically correct appendages. They are the same resolution (1024x1024) as the vanilla "race" files they replace(Since this is classified as an "Adult" mod, a direct link is against Nexus rules. With the full mod and authors name you should be able to search it out on your own.)
+
* Cause: Install failures, usually from not understanding what is involved.
 +
:* Solution: This is a general guide to what is involved in replacing the vanilla body of one gender with a "Custom Race" one for the Player Character Only. Mods for NPCs are separate.  There are separate mods for Males and Females or other Custom Races.  Refer to the specific body mod install instructions for specific details appropriate to that mod.  But understanding what is involved will make it easier to understand those options.  For another detailed explanation, see the [http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice#Body_Replacement_Basics Body Replacement Basics] section of the "FNV General Mod USE Advice" article.
 +
 
 +
:: Replacing the vanilla body involves two different sets of files: "meshes" and "textures", which usually come as separate modsMods labelled "body type" are actually "meshes" that have a different shape (proportions) in some regards to those used for the vanilla body. They are generally going to be found in the Nexus site [http://www.nexusmods.com/newvegas/mods/searchresults/?src_cat=66 New Vegas Models and Textures] category.  
  
:* Related:
+
:: Body replacement only affects the "unclothed" body. "Clothing" and "armor" (collectively: "garments") have their own "body shape", which is independent of that of the underlying body. They do not "warp around" or "conform to" the underlying body; they completely replace it. If you have body replacement type "A" and clothing/armor for body type "B", what you see is type "B"So the "nude" body type does not appear at all; even the "bare skin" elements are part of the garment. ALL "garment" mods are based around some body type (assume "vanilla" if not specified)FNV does not have separate "slots" for different parts of the body: only distinguishing between the head, hands, and the remainder of the body (misleadingly called "upper body slot" as there is no "lower body" nor "legs" slot). Further on the consequences of this below.

<span id="Issue: Body Replacer - FCO ("Fallout Character Overhaul") not working or conflicting"></span>
+
:: The vanilla body "texture" has underwear included, so it is not removable.  Custom body textures may have both a "nude" option and an "underwear" option texture.  These are "all-or-nothing" choices: everyone is nude underneath their armor and clothing, or everyone wears underwear.  Select a custom body ''texture'' mod that is designed to be compatible with your custom body type (i.e. the ''mesh'') mod.  Otherwise you may have apparent "black bands" around the groin area or huge scars on the breasts because the ''vanilla texture'' (used by default) doesn't fit correctly to the adjusted body mesh.  There is now at least one "nude body" texture mod for vanilla meshes: ''Simple Vanilla Nude Body Replacers'' by '''Jokerine''' (linked below under "NPC overhauls").  Toggling "ArchiveInvalidation" off-and-then-on again as with other texture replacements may be necessary.
  
=== Issue - Body Replacer - Fallout Character Overhaul ''aka FCO'' not working or conflicting ===
+
:: As a consequence of these custom meshes, vanilla clothing and armor will have "clipping" issues where body parts show through or don't seem to "fit" correctly leaving gaps or seamsSome "clipping" is minor, but often it is major enough that you have to also install mods for clothing and armor that are made specifically for that body type. Note that armor usually has it's own "body mesh" included, avoiding this clipping. (This is not true for "accessories" that go on sub-sets of the body: such as gloves, bracers, and shoes.) This means armor ignores the underlying "body" shape and instead that you can choose among those using the same texture '''UVmapping''' based upon the same base model (i.e. Type 6M, Type 6, Type 4, Type 3M, Type 3F, and Type 3).  As a consequence, your Type 6 naked body can "wear" a Type 3 armor, but will appear to be Type 3 in proportions until it is taken off.
* Cause-1: Usually the problem is not understanding or following the installation instructions.
 
: Note that FCO is a "high resolution" texture replacement of characters and NPCs.  These will place additional demands upon your video systemNot all older systems will be able to handle the challenge.
 
: The extensive [http://forums.nexusmods.com/index.php?showtopic=1257503 FCO "comments" forum thread] on the subject has the answers to pretty much every conceivable question not answered here.  Use the forum search function.
 
:* Solution-1: Make sure you have complied with the following requirements:
 
::* Install the latest version of [http://nvse.silverlock.org/ NVSE] (currently 5.1b4).
 
::* Install [http://www.nexusmods.com/newvegas/mods/57174/? User Interface Organizer] (UIO).
 
::* Have the official "Old World Blues (OWB)" DLC installed and active.
 
::* Use one of the mod managers recommended by the author, or understand enough to be able to manually install it yourself.  If you can't or have to make a choice then use of [http://www.nexusmods.com/newvegas/mods/54991/ Fallout Mod Manager - Forked (FOMM-Forked)] is recommended as FCO has an install wizard written for it.
 
::* Only install optional components of FCO you actually needWhen in doubt, don't.  You can add them later.
 
::* Toggle your "ArchiveInvalidation" off-and-on again after installing FCO, as it is replacing texture files.
 
::* Start a new game either upon installing or uninstalling FCO.  The changes it makes to characters are such the effects upon a game in progress are not supported.
 
  
* Cause-2: "Fallout Character Overhaul" (FCO) v3.01 has some bugs that can make it unplayable if you don't understand how to correct them yourself.
+
:: "B-n-B" or "Bouncing Breasts and/or Butts" mods are meshes based upon a different "armature" or "skeleton" rigged with added "bones" (e.g. "breast bones") and weights to support the "bouncing" parts. (These different bones and weights are also the case with some "Havok" and "Power Armor" mods.)  They will either provide or tell you to use a specific "skeleton" in order to work correctly.  Without that customized skeleton, the "bouncing" parts will not bounce and may appear "deformed" (i.e. stretching out to the horizon) or otherwise appear "weird".  There is only one skeleton used by each race in the game, so it will not adversely affect any "non-bouncing" meshes which will just ignore the added bones they don't know about.  As a consequence, in order to see the "bouncing" effect in clothing and armors, you may need to install mods with those "bouncing" features enabled.  Sometimes special animations for certain actions (i.e. walking, sneaking, jumping, swimming, dancing) are also available.  Not all mods can use the same specialized skeleton, so check the description/documentation for each carefully.  This "skeleton" choice can easily limit your options. There are three "universal compatibility skeleton" mods for FNV on '''Nexus''' designed to overcome this compatibility problem:

<span id="Issue: Body Replacer - FCO or FNV Redesigned3 Characters have pink faces or clean bodies with dirty faces"></span>
+
:: Because the head is separate from the body, that means it too can have custom versions of it's mesh and textures.  In all other regards it is similar to but independent of the body.  As the head (hair and face) is a separate component from the rest of the body, custom meshes often have a problem with a visible "seam" where the head mesh joins with the body meshIt is just a fact of life you will have to live with; nothing the mod creators can completely eliminate (though some come very close)There are "seam concealer" mods that provide necklaces and similar to hide this seam.
=== Issue - Body Replacer - FCO or FNV Redesigned3 Characters have pink faces or clean bodies with dirty faces ===
 
* Cause: While FCO and FNV Redesigned3 (FNVR3) can work together, there are often difficulties such as pink/magenta faces or fiends/raiders who normally are "dirty" looking suddenly having "clean" bodies with dirty faces depending upon the options chosen for each mod.
 
:* Solution: While the FNVR3 recommendation is to install it after FCO, the proper solution is a "compatibility patch file" between the two modsFinally there is one specifically to address this issue.  Make sure you have all patch files provided by either mod installed firstThen install the mod [http://www.nexusmods.com/newvegas/mods/63230/?

Commonly seen with [http://www.nexusmods.com/newvegas/mods/54460/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fnewvegas%2Fajax%2Fmodfiles%2F%3Fid%3D54460&pUp=1 Fallout Character Overhaul (FCO)] (designed to remodel NPC faces) in combination with various other character mods and mods that affect appearance, especially eyes.  This often is related to attempts to use both FCO and "Fallout New Vegas Redesigned" (FNVR; similar goal) in combination.
 
  
* Cause-1: Mod conflict with FCONote the older version (v2.3.1) is available on the same download page under "Old Versions".
+
:: Some features, such as scars and tattoos, are part of the texture and not a separate addition.  Others have to use specific [http://geck.bethsoft.com/index.php?title=Race body part slots], which are broken down into "Body Data", "Face Data", and "FaceGen Race".  Only one mesh can be assigned to each body partFor instance, "Face Data" has only "Eye colors" and "Hair styles". Which in turn means you can have "hair" or a "hat/helmet" but not both. If there is hair showing under a hat or helmet, it is part of that "hat" mesh.  FNV does not have a separate slot for "facial hair" (i.e. beards, mustaches, "mutton chops", etc.).  Mod authors have to cannibalize the use of a different slot for the purpose, or make the facial hair part of the texture itself.
:* Solution-1: The current version of FCO is v3.01, which has new eye textures.
 
  
* Cause-2: According to the author of all FNVR versions, with FNVR3 the correct approach in conjunction with FCO3 is to use one or the other.  'Although FCO will "technically" work with New Vegas Redesigned 3, it's best not to. It's best to use one or the other. But not both. This makes it so that you will get New Vegas Redesigned 3's faces instead of the ones in FCO and it leaves the characters I left alone (ie. Lt. Monroe), etc. alone.' A more detailed expanaition can be found in [https://forums.nexusmods.com/index.php?/topic/1876875-new-vegas-redesigned-3/page-96#entry16892164 the FNVR3 forum thread].

:: Because they use a slot on the head, custom "Hair" and "Eye" mods can get complex to install. Sometimes they require using the GECK to add their mesh and textures to the "head" modRead their installation instructions carefully before choosing.

:* Solutions-2: As FCO3 does not work well with "Fallout New Vegas Redesigned" (FNVR), despite the author's advice people have had some success (with the same caveats as listed in the post above) using FCO2 instead of FCO3 in combination with FNVR2Any one of the following may also be required to resolve the "eye roll" problem.

:: Q: What is the difference between Body Type 3 and Body Type 6M, etc?<br>
=== Issue - Body Replacer - FNV Redesigned 3 ''aka FNVR3'' and Qwinns Refined FNV Redesigned 3 ''aka QRNVR3'' ===
+
:: A: It's a matter of personal preference in "shape": breast, hip and/or butt size.  All are potentially weighted differently ("bounce" effect).  Type 6 has an "apple bottom", Type 3 are thinner "waifs".  Apparently T3 originated in Fallout 3 along with Type V; Type 6 (another variant of Type 3) by '''Necroscope''' came along when NV came out, but has since been hidden by the author.  Type 6M (by '''Izumiko''') is a "rounder" modification of the basic Type 6 model.  Why do they have numbers? Your guess is as good as any. Any that have T3 in the name are derivatives of the original Dimonized Type 3 set from Fallout 3 (variants: Alice, Berry, Cali = A Cup, B Cup, C Cup).
'''Dracomie''''s "Fallout New Vegas Redesigned 3 (FNVR3)" mod is often combined with '''Drumber''''s "Fallout Character Overhaul (FCO)" modThis can be done successfully, but requires close adherence to the '''FNVR3''' install instructionsEven so, many people have had problems with crashes and performance in heavily modded games.
+
:::* HD versions have more polygons, which place a heavier demand on the video memory.
 +
:::* Hentai versions have puffy nipples and are based on T3F.
 +
:::* It's best to use clothing and armor specific to the particular body type or they won't render properly.  And it's not simple to "fix".
 +
 
 +
:: Q: Can Body Type6M (or T6, Type V/T5, T3BG, or T3M) can be used with textures for Body Type3?<br>
 +
:: A: Yes, if they have the same '''UVmapping''' (part of the texture "*.dds" file).  However, the dimensions of the armor will not change from the Type3 to the others.  The armor contains it's own body mesh.  (See the next question.) The mod [http://www.nexusmods.com/newvegas/mods/67079 Wasteland Gals - Body Textures and Playable Races Type 3 4 6] is a retexture of type 3, 4 and 6 female bodies and faces that makes raiders, ghouls and old people playable.  (Note the caveats near the bottom of the description carefully.)
  
* Cause: The mod has been in production since '''FNV''' was released in 2010, and it's never had a thorough cleaningOver the near-decade that '''Dracomies''' has spent working on it, the '''GECK''' added tons of wild edits (it does that), and there were even some obsolete values from before the '''Fallout Official Patches''' were applied back in 2010/2011 still lurking in the plugins.
+
:: Q: What about clothing and armor compatibility between body types?<br>
: In addition, '''FNVR3''' relied on both an ESM and an ESP plugin.  The main reason for the ESP is that when "NPC Actor" records are stored only in an ESM, you can get visual glitches such as what some call "whiteface", generally intense bright discoloration.  '''FNVR3''' also suggests setting ''bLoadFaceGenHeadEGTFiles=1'' in the various INI files to further help with this problem, but that setting is an intense resource hog (it generates textures for every character on the fly while in game), which is a lot to ask of your modded setup on what is already a fairly unstable engineThere is a better way to resolve this though, using the "Export Face Textures" feature in the '''GECK''', eliminating the need for an ESP file.
+
:: A: Compatibility is a problematic term to use in this case.  Generally, the only thing that is needed for the body types and associated armors to work together is for them to share the same '''UVmap'''.  Any mesh that shares a '''UVmap''' can also share textures.  And generally the ones that are variations on Type3 do.  There are more choices for Type3 bodies than any others.  Remember: the "garment" completely replaces the body supposedly underneath it.  You are seeing the shape of the garment mesh, not that of the naked body.
 +
::: "BnB" is a little more complicated.  Basically, in order to use BnB you have to have the skeleton.  So you can't just take an individual BnB outfit and have it work unless you've downloaded the skeleton from the main file.  The reason is because the outfit will have two reference bones (left breast and right breast) that aren't in the normal skeleton, and that causes glitches or crashes.  But you can have the BnB stuff installed and still use other non-bounce outfits, because those outfits don't need the extra bones.
 +
::: Now, if your idea of compatibility is for your character's body to stay the same size no matter the outfits, then you're generally out of luck.  For the time you're wearing an outfit, your body will be that size, for most things.  This is because virtually all major outfits include their own body meshes as part of the outfit.  The exception are accessory-type items like individual shirts or shorts or whateverThose are usually fitted to a particular body that is NOT included in the mesh file, and in this case if you're not using the right body then the clothing will clip badly.  As always, read the documentation carefully.
 +
::: However, with that said, there was a tool called [http://kgtools.wordpress.com/clothing-converter/ KGTools Clothing Converter].  This would automatically convert Armor, Clothing, or Equipment from one body style to another!  Unfortunately the KGTools web site containing the downloads is no longer accessible.  Use the links [http://www.loverslab.com/topic/27557-new-clothing-body-style-converter-beta-v089f-10-26-2014/ on this site (adults 18+ only)] instead.  The documentation is still available on the first link provided.
  
:* Solution: The mod [http://www.nexusmods.com/newvegas/mods/65865 Qwinn's Refined FNV Redesigned 3 (QRNVR3)] by '''Qwinn''' is an authorized overhaul of FNVR3 to cleanup all the old issues.  The mod is currently a "beta test" of the cleanup which, if successful, will be rolled into the official '''FNVR3''' release.  It is applied as a "patch" to an existing '''FCO+FNVR3''' installation, and takes care of the question about disabling the '''FCO''' ESM file by replacing it with an empty "dummy" version.
+
:: Q: Can I use a different body type for my companions (and NPCs) than for my character?<br>
:: Qwinn has authored two articles to supplement QRNVR3:
+
:: A: Yes, as long as they have their own ''male/femaleupperbody.nif'' file.

<span id="Issue: Body Replacer - In-game doesn't look quite like the author's images"></span>
+
: In summary, you can expect to need "Body Type", "Body Texture", "Clothing and Armor", and possibly "Head", "Hair", and "Eyes" mods that are all compatible to work together.
=== Issue - Body Replacer - In-game does not look quite like the authors images ===
 
* Cause: Mod authors usually choose 3rd Person "poses" available from other mods to show off their results.  Those poses accentuate the figure in a way that the normal in-game animation does not.  Also, the game has a horrible "fisheye lens" effect with the default of 75 or higher "Field of View" (FoV).  The problem lies with the way the game is displaying the image. For screenshots modders and imageshare users tend to greatly reduce the FoV to correct the problem, sometimes going as low as 30 or even 20.  The game is unplayable with the FoV this low; but it makes for better character screenshots.
 
:* Solution: Ignore it, or play around with the FoV using a mod such as [http://www.nexusmods.com/newvegas/mods/55085 FOV Slider].  However, note there are several different FoV settings and they have some impact upon each other.  The mod [http://www.nexusmods.com/newvegas/mods/36773 Further 3rd Person Camera] for normal game play may also help.

Many people have had problems getting this to install. The following needs to be understood.
+
Problems getting custom heads or head elements (e.g. Hair and Eyes) to work correctly with a specific body replacement mod.
  
* There is more than just the body to consider when replacing appearance.  Please see the [[#Issue:_Body_Replacer_-_Custom_Body_Types|Issue: Body Replacer - Custom Body Types]] section of this article.
+
* Cause-1: As pointed out in [[#Issue:_Body_Replacer_-_Custom_Body_Types|Issue: Body Replacer - Custom Body Types]] you can't just assume every mod affecting the head will work with every other, or even with the body mod you have chosen. They are not "mix-n-match" and you can only use one such mod at a time for each race.  For example, if it says it's for "Head03", then it won't work with the vanilla game heads.  The popular mod [http://www.nexusmods.com/newvegas/mods/44312/? Mojave Delight for Type3] by '''Glosshouse''' is for '''Type3''' bodies only, while [http://www.nexusmods.com/newvegas/mods/35878/? Beauty Pack PLUS -Project Mikoto- Hair - Eyes - Presets] by '''Matteius''' is not intended to work with any [[custom race]] body mods like '''Type3'''. Read the description and installation instructions carefully to determine what the mod is designed to work with.  Most known issues are noted either on the description page or under the "comments" page.  Note that some require MANUAL installation.
* BoG is a high resolution ''texture'' FOR Type3 bodies, not vanilla bodies.
 
* BoG is not itself a "body replacer" mesh.
 
* BoG is designed for Type3 bodies, NOT vanilla bodies. (Yes, this is almost the same thing as the first point, but it bears repeating.)
 
* If you only install this BoG ''texture'' replacer on vanilla bodies, there will be ugly underwear seams on a naked body. Like two textures/meshes are conflicting.
 
  
* To use this body mod (BoG), you should install a Type 3 Body & Armor ''mesh'' Replacer. An example would be [http://www.nexusmods.com/newvegas/mods/34825/? Type3 Body and Armor replacer] by '''Exeter'''.  It is not the only one.

<span id="Issue: Body Replacer - Type 6M?"></span>
+
* Cause-2: Unsuccessfully trying to switch between race or hair mods.  The character becoming invisible, getting stuck in the ground and unable to even use the console to toggle the "clipping" command (''TCL''), or unable to access the Pip-boy, usually happens if you uninstall/disable the race that your character is set to.  Trying to use the console command "''ShowRaceMenu''" here will probably crash the game.
 +
:* Solution-2: Instead reinstall and enable whatever mod contains the race you were playing, then use the console ''ShowRaceMenu'' command to switch to something else vanilla before removing it again.  Then perform a "Clean Save" as laid out in the 'Clean Saves' section of the wiki "FNV General Mod Use Advice" article before attempting to install a replacement.

=== Issue - Body Replacer - Type 6M ===

<span id="Issue: Body Replacer - Custom Race skin mismatch"></span>
Problems getting this body replacer to work correctly.
 
  
* Cause: You need, in addition to a Type 6 body replacer, the correct body ''texture'' and "clothing and armor" modsSuch mods usually need to be installed MANUALLY. Read their documentation carefully.
+
=== Issue - Body Replacer - Custom Race skin mismatch ===
:* Solution: Type 6 bodies are based upon Type 3 bodies. This makes many Type 3 based mods compatible with Type 6. (An "M" suffix just means it is slightly modified from the base Type body in some dimension. This is usually not enough to make it sufficiently different to cause problems.)  Keep in mind the ''meshes'' are separate from the ''textures'', but the ''meshes'' contain the path to the ''texture'' files they use. Common choices that work are:

:: If you are using this on an NPC, make sure the NPC is defined in an ESM and not in an ESP. There are some tweaks to your INI files that can kinda fix it for ESP files, but they don't work for everyone.

::* Toggling "ArchiveInvalidation" sometimes works, as does repeatedly reloading the save game again and toggling it until the head and body match skin tones.
  
* Cause: According to the author "Just Mods: The Hit Indicator" textures from [http://www.nexusmods.com/newvegas/mods/66666 Just Mods Assorted] (2.6d) only support high texture size.
+
:: It is also possible that the shader type and shader flags are set wrong in the race's body mesh. Skin parts need the shader type to be ''SHADER_SKIN'', and the ''SF_Specular'', ''SF_Skinned'', ''SF_FaceGen'', ''SF_Remappable_Textures'', and ''SF_ZBuffer_Test'' flags need to be set. You can check and modify these using '''NifSkope'''. If these are not set properly, then the custom race body and skin won't work properly for both NPCs and for the player, if the player uses that race.
:* Solution: Go to "settings" [SIC] and change your texture size to "High".
 
:: NOTE: The comments page indicates that some individual "Just" mod components work fine when installed separately; but not when installed as part of the umbrella "Just Assorted" package.  YMMV.
 
  
<span id="Issue: Character is suddenly invisible in both 1st and 3rd person views"></span>
+
:: Another thing to check is that the skin textures are all there and are all named properly. If the body texture for the race is named '''UpperBody.dds''', then the normal map needs to be named '''UpperBody_n.dds''' and the skin needs to be '''UpperBody_sk.dds''', and all of those files need to be in the same folder. You only define the base texture ('''UpperBody.dds''') for the race in the '''GECK''''. The '''GECK''' just assumes that the other files will be in the same place and will have the same name.
  
===Issue - Character is suddenly invisible in both 1st and 3rd person views===
+
:: And finally, keep in mind that whatever '''clothes''' or '''armor''' you use will have body parts defined, and those skin textures will show instead of whatever body you have defined in the '''GECK'''. In other words, if your character is wearing overalls and bare arms are visible, those bare arms are part of the overalls mesh and are not the bare arms from the race's body mesh. If the clothing wasn't created especially for your custom race, the bare skin parts of the outfits might not match the rest of your custom body type.
Upon opening a save, the player character is suddenly invisible except for their shadow. NPCs act like the character is present.  Loading an earlier save doesn't have the problem.
 
  
* Cause: Unknown, but might be related to use of the game "Auto-Save" feature.

No matter your opinion of the matter, one of the most common reasons for installing a "body replacer" is to enable a "nude body" when clothing and armor are removed.

Some would prefer to not have to get into the complexities of resorting to "custom races" to get this feature.

=== Issue - Body Replacer - Fallout Character Overhaul ''aka FCO'' not working or conflicting ===
 +
* Cause-1: Usually the problem is not understanding or following the installation instructions.
 +
: Note that FCO is a "high resolution" texture replacement of characters and NPCs.  These will place additional demands upon your video system.  Not all older systems will be able to handle the challenge.
 +
: The extensive [http://forums.nexusmods.com/index.php?showtopic=1257503 FCO "comments" forum thread] on the subject has the answers to pretty much every conceivable question not answered here.  Use the forum search function.
 +
:* Solution-1: Make sure you have complied with the following requirements:
 +
::* Install the latest version of [http://nvse.silverlock.org/ NVSE] (original version from the Silverlock site has been at 5.1b4 for many years.  The current version known as "xNVSE" from [https://github.com/xNVSE/NVSE GitHub] is in version 6.x).
 +
::* Install [http://www.nexusmods.com/newvegas/mods/57174/? User Interface Organizer] (UIO).
 +
::* Have the official "Old World Blues (OWB)" DLC installed and active.
 +
::* Use one of the mod managers recommended by the author, or understand enough to be able to manually install it yourself.  If you can't or have to make a choice then use of [http://www.nexusmods.com/newvegas/mods/54991/ Fallout Mod Manager - Forked (FOMM-Forked)] is recommended as FCO has an install wizard written for it.
 +
::* Only install optional components of FCO you actually needWhen in doubt, don't.  You can add them later.
 +
::* Toggle your "ArchiveInvalidation" off-and-on again after installing FCO, as it is replacing texture files.
 +
::* Start a new game either upon installing or uninstalling FCO.  The changes it makes to characters are such the effects upon a game in progress are not supported.
  
<span id="Issue: Distant terrain/LOD flickers rapidly"></span>
+
* Cause-2: "Fallout Character Overhaul" (FCO) v3.01 has some bugs that can make it unplayable if you don't understand how to correct them yourself.
=== Issue - Distant terrain or LOD flickers rapidly ===
+
:* Solution-2a: The author recommends the authorized patch [http://www.nexusmods.com/newvegas/mods/61357/? FCO Bugfixes] by Lunarion Silver to correct these issues.
This problem seems to occur more frequently with high-end systems, but across all sorts of platforms and video cards.
+
:* Solution-2b: [http://www.nexusmods.com/newvegas/mods/64012/? Fallout Character Overhaul - Pink Hands Fix] by Vainlash.
* Cause: Known as "Z-fighting" or "stitching", this is a complex problem in 3D rendering where two or more "primatives" such as "layers" have similar or identical values in the "z-buffer", so they essentially occupy the same space. The result is the pixels from each layer "fight" to be the one displayed on screen, especially when the point of view changes. This causes a flickering, noisy display of first one then another color pixel.  See the "[https://en.wikipedia.org/wiki/Z-fighting Z-fighting]" article from Wikipedia for the full technical description.
+
:* Solution-2c: Other mods may also have their own patches for FCO.  Be sure to check the download pages for any mods already installed for "compatibility patches" for FCO.  Be careful as to which version of FCO each patch is designed to work with.
  
* Solution: There is no single solution that applies to every system, and some of these effects cannot be resolved by the player.  See the S.T.E.P. Project Guide [http://wiki.step-project.com/Guide:Z-Fighting Z-Fighting] for examples of the issue and some INI tweaks that may help.  An FNV user tried some similar suggested in [https://www.youtube.com/watch?v=XjHt-4Z6PwI Gopher's "Mountain Flicker and Z-Fighting" video] and had the most success with adjusting the "fNearDistance=" value under [Display] in the "FalloutPrefs.INI" file.  He reports that anything above "10" results in clipping with arms and weapons in first person mode, but a balance can be reached with some testing.

=== Issue - Body Replacer - FCO or FNV Redesigned3 Characters have pink faces or clean bodies with dirty faces ===
=== Issue - Entering an Interior spawns the player in a huge ball of items and NPCs ''aka '''junkado''''' or '''''junknado''''' ===
+
* Cause: While FCO and FNV Redesigned3 (FNVR3) can work together, there are often difficulties such as pink/magenta faces or fiends/raiders who normally are "dirty" looking suddenly having "clean" bodies with dirty faces depending upon the options chosen for each mod.
Also sometimes referred to as a "vortex on junk" or "compacting of cell contents".
+
:* Solution: While the FNVR3 recommendation is to install it after FCO, the proper solution is a "compatibility patch file" between the two mods.  Finally there is one specifically to address this issue.  Make sure you have all patch files provided by either mod installed first.  Then install the mod [http://www.nexusmods.com/newvegas/mods/63230/? Fallout Character Overhaul Pink Faces fix] by '''Fheese'''.  See the comments for additional information.
  
* Cause-1: This has been traced to a corrupt ESM plugin from the mod [http://www.nexusmods.com/newvegas/mods/50817/? CAM - Chems Alcohol and Meds] by '''SenterPat'''.
+
<span id="Issue: Body Replacer - FCO or FNV Redesigned3 Eyes rolled to the side"></span>
:* Solution-1: The problem has been fixed in version 9 of the mod.  Apparently it was resolved by removing the internal file header "ESM" flag from the ESP file.
+
=== Issue - Body Replacer - FCO or FNV Redesigned3 Eyes rolled to the side ===
* Cause-2: File "FINAL Searchlight Airport NCR.esm" in mod [http://www.nexusmods.com/newvegas/mods/40324 Searchlight Airport NCR or Legion].  To put it simply, this mod makes a few minor adjustments in the "Camp Forlorn Hope Messhall" cell, which wouldn't be an issue except it moves one of the decals to something like (-3000) under the cell. No idea why the game responds this way, but the result is that the decal inexplicably pulls everything not nailed down along with it. Its like a powerful electromagnet dragging everything along the ground.
+
Commonly seen with [http://www.nexusmods.com/newvegas/mods/54460/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fnewvegas%2Fajax%2Fmodfiles%2F%3Fid%3D54460&pUp=1 Fallout Character Overhaul (FCO)] (designed to remodel NPC faces) in combination with various other character mods and mods that affect appearance, especially eyesThis often is related to attempts to use both FCO and "Fallout New Vegas Redesigned" (FNVR; similar goal) in combination.
:* Solution-2a: Thanks for '''Merik2013''' for diagnosing the source and solution to the problem.  He simply reset that decal back to its default settings and everything went back to normal. You probably could also just delete it from that ESM as wellAs always, make backups of the mods before editing.
 
::* The cell is '''CampForlornHope01''' and the decal is ''NVNCRDecalCLeg''. You'll want to right click the decal and click the "edit" option.
 
::* Its the Z Position that needs to be changed. He changed it to its default value, which is 671.1060. Also disabled (unchecked) all the miscellaneous changes made to it just to be sure it took, but that might not be necessary. The changes the mod made were enabling the "Persistent Reference" and "Initially Disabled" options as well as the "Flags: Set Enable State to Opposite of Parent " option under the "Enable Parent" tab. (The last has also been suggested as a possible general fix to the problem on it's own.)
 
  
:* Solution-2b: Thanks to '''Roy Batty''' for the following:
+
* Cause-1: Mod conflict with FCO.  Note the older version (v2.3.1) is available on the same download page under "Old Versions".
::* Go into '''FNVEdit''' and change the cleaning setting "set z -<some high number>" (ex: -3000) and TURN IT OFF.
+
:* Solution-1: The current version of FCO is v3.01, which has new eye textures.
::* Reclean your mod.
 
::: (Note this solution predates v4.x of '''FNVEdit''' which has replaced such settings with the "AutoClean" function. Presumably this is implemented in that function but we lack reports on how effective it is for this purpose, which is why it is not the primary solution.)
 
  
:* Solution-2c: Thanks to '''user826''' for experiments based upon the above "Solutions" leading to the following theory for mod creators:
+
* Cause-2: According to the author of all FNVR versions, with FNVR3 the correct approach in conjunction with FCO3 is to use one or the other'Although FCO will "technically" work with New Vegas Redesigned 3, it's best not to. It's best to use one or the other. But not both. This makes it so that you will get New Vegas Redesigned 3's faces instead of the ones in FCO and it leaves the characters I left alone (ie. Lt. Monroe), etc. alone.' A more detailed expanaition can be found in [https://forums.nexusmods.com/index.php?/topic/1876875-new-vegas-redesigned-3/page-96#entry16892164 the FNVR3 forum thread].

 +
=== Issue - Body Replacer - FNV Redesigned 3 ''aka FNVR3'' and Qwinns Refined FNV Redesigned 3 ''aka QRNVR3'' ===
 +
'''Dracomie''''s "Fallout New Vegas Redesigned 3 (FNVR3)" mod is often combined with '''Drumber''''s "Fallout Character Overhaul (FCO)" mod.  This can be done successfully, but requires close adherence to the '''FNVR3''' install instructions.  Even so, many people have had problems with crashes and performance in heavily modded games.
  
=== Issue - Female Character strafing left modelling glitch ===
+
* Cause: The mod has been in production since '''FNV''' was released in 2010, and it's never had a thorough cleaningOver the near-decade that '''Dracomies''' has spent working on it, the '''GECK''' added tons of wild edits (it does that), and there were even some obsolete values from before the '''Fallout Official Patches''' were applied back in 2010/2011 still lurking in the plugins.
The left arm appears totally mangledOnly seems to affect female models, and persists even if the entire FNV game and "Users\<acct>\documents\My Games\FalloutNV" folders are deleted and re-installed with only vanilla files (no mods).
+
: In addition, '''FNVR3''' relied on both an ESM and an ESP plugin.  The main reason for the ESP is that when "NPC Actor" records are stored only in an ESM, you can get visual glitches such as what some call "whiteface", generally intense bright discoloration.  '''FNVR3''' also suggests setting ''bLoadFaceGenHeadEGTFiles=1'' in the various INI files to further help with this problem, but that setting is an intense resource hog (it generates textures for every character on the fly while in game), which is a lot to ask of your modded setup on what is already a fairly unstable engine.  There is a better way to resolve this though, using the "Export Face Textures" feature in the '''GECK''', eliminating the need for an ESP file.
  
* Cause: Why the problem persists through a re-install is unknownHowever, the cause appears to be related to the "left movement" animations used.
+
:* Solution: The mod [http://www.nexusmods.com/newvegas/mods/65865 Qwinn's Refined FNV Redesigned 3 (QRNVR3)] by '''Qwinn''' is an authorized overhaul of FNVR3 to cleanup all the old issues.  The mod is currently a "beta test" of the cleanup which, if successful, will be rolled into the official '''FNVR3''' releaseIt is applied as a "patch" to an existing '''FCO+FNVR3''' installation, and takes care of the question about disabling the '''FCO''' ESM file by replacing it with an empty "dummy" version.
:* Solution: For at least one user this was "mitigated" (though not actually resolved) by downloading a "BnB" (Bouncing Natural Breasts) skeleton and copying the "left movement" animations located in that mod's "meshes\characters\_male\female" folder to that of the "Data" folder tree.

+
=== Issue - Body Replacer - In-game does not look quite like the authors images ===
There can be a problem with the mod [https://www.nexusmods.com/newvegas/mods/55334 New Vegas - Enhanced Camera] by '''LogicDragon''' when drawing a weapon (even bare hands) in "First Person View" while wearing Power Armor or Elite Riot Armor in which half of the view is blocked by the left shoulder pauldron.
+
* Cause: Mod authors usually choose 3rd Person "poses" available from other mods to show off their results.  Those poses accentuate the figure in a way that the normal in-game animation does not.  Also, the game has a horrible "fisheye lens" effect with the default of 75 or higher "Field of View" (FoV).  The problem lies with the way the game is displaying the image. For screenshots modders and imageshare users tend to greatly reduce the FoV to correct the problem, sometimes going as low as 30 or even 20.  The game is unplayable with the FoV this low; but it makes for better character screenshots.
 +
:* Solution: Ignore it, or play around with the FoV using a mod such as [http://www.nexusmods.com/newvegas/mods/55085 FOV Slider].  However, note there are several different FoV settings and they have some impact upon each other.  The mod [http://www.nexusmods.com/newvegas/mods/36773 Further 3rd Person Camera] for normal game play may also help.
  
* Cause: This is due to a bug in the mod [http://www.nexusmods.com/newvegas/mods/51664 Yukichigai Unofficial Patch - YUP] that makes it so the Riot Armor family has its left shoulder appear in first person.  The source of the problem seems to be from YUP version 11.3 onwards (and possibly earlier versions.) The YUP team is aware of the problem, but it has not been fixed as of version 11.7.  The same problem has also been referenced in the "Enhanced Camera" comments without attributing it to YUP.

:* Partial Workaround: The mod [http://www.nexusmods.com/newvegas/mods/65496 Elite Desert Combat Gear] offers a Desert Ranger Combat armor and helmet with the same stats as Elite Riot gear. The helmet is however still light armor to reflect the changes made by YUP.
+
* There is more than just the body to consider when replacing appearance. Please see the [[#Issue:_Body_Replacer_-_Custom_Body_Types|Issue: Body Replacer - Custom Body Types]] section of this article.
 +
* BoG is a high resolution ''texture'' FOR Type3 bodies, not vanilla bodies.
 +
* BoG is not itself a "body replacer" mesh.
 +
* BoG is designed for Type3 bodies, NOT vanilla bodies.  (Yes, this is almost the same thing as the first point, but it bears repeating.)
 +
* If you only install this BoG ''texture'' replacer on vanilla bodies, there will be ugly underwear seams on a naked body. Like two textures/meshes are conflicting.

+
=== Issue - Body Replacer - Type 6M ===
 +
Problems getting this body replacer to work correctly.
  
=== Issue - Flickering Shadows on grass ===
+
* Cause: You need, in addition to a Type 6 body replacer, the correct body ''texture'' and "clothing and armor" mods.  Such mods usually need to be installed MANUALLY.  Read their documentation carefully.
* Cause: Video settings issue.
+
:* Solution: Type 6 bodies are based upon Type 3 bodies.  This makes many Type 3 based mods compatible with Type 6.  (An "M" suffix just means it is slightly modified from the base Type body in some dimensionThis is usually not enough to make it sufficiently different to cause problems.) Keep in mind the ''meshes'' are separate from the ''textures'', but the ''meshes'' contain the path to the ''texture'' files they use. Common choices that work are:

* Solution-2: Edit each floating object in the "console window" (typically toggled with the "~" key), and then save the game.  The result would persist from that save game point onwards.  However it will re-appear if an earlier save were loaded, or a new game started, or a new mod added which also conflicts: so it is only a temporary solution to that specific conflict.  The edit would consist of:
 
:* Click on the floating object.
 
::* Use the "getpos [x|y|z]" commands, where "x"= is the '''horizontal''', "y" is the '''vertical''', and "z" is 'the '''height''' above the water table (AKA "ground level")' axis location in the cell.  Each axis must be retrieved individually, i.e. "getpos x", "getpos y", and "getpos z".  Record each result.
 
::* Use the "getangle [x|y|z]" commands in the same manner.  Record each result.
 
::* Use the "setpos z 0.00" command to reset the height of the object to "ground level".  Note the floating decimal number value.
 
:: The record of "getpos" and "getangle" entries will enable you to restore things with the appropriate "setpos" or "setangle" commands if anything goes wrong.
 
:* Repeat the above steps for each floating object as needed.
 
:* Make a "full save" to a new "save game" slot.
 
  
<span id="Issue: Fog effect around the Vegas Strip"></span>
+
* Cause: According to the author "Just Mods: The Hit Indicator" textures from [http://www.nexusmods.com/newvegas/mods/66666 Just Mods Assorted] (2.6d) only support high texture size.
=== Issue - Fog effect around the Vegas Strip ===
+
:* Solution: Go to "settings" [SIC] and change your texture size to "High".
* Cause: The area around New Vegas (outside the strip itself) uses the "NVWastelandHazy" weather type which includes the same effect that the distance fog does, but it's set as if the distance is nothing (-10) causing it to be present right where you are. Apparently it's there to give everything a sort of dirty/dusty appearance, as if lots of sand and dirt has been kicked up by the amount of human activity around Vegas.  The weather that does that nasty looking fog is "NVUrbanClear [WTHR:00173564]".
+
:: NOTE: The comments page indicates that some individual "Just" mod components work fine when installed separately; but not when installed as part of the umbrella "Just Assorted" package. YMMV.
:* Solution: Forcing the weather from "NVUrbanClear [WTHR:00173564]" to "NVWastelandHazy [WTHR:00100A4E]" will remove the fog.  "NVWastelandClear [WTHR:000FFC88]" doesn't "fog".
 
:: Looking at NVUrbanClear, it has '''FNAM - Fog Distance''' Day & Night "- Near fog" set to "-10". ("NVWastelandClear" does as well), although during the night time it doesn't fog your eyes.
 
:: So essentially to get rid of the fog using '''FNVEdit/xEdit''', you would expand the "Weather" '''Object''' category, select "NVUrbanClear", and then scroll down to "FNAM - Fog Distance" and change "Night - Near" from "-10" to "2000"; and also for "NVWastelandClear" change both "Night - Near" and "Day - Near" from "-10" to "2000". Any Fog setting that is "-10" should be set to "2000" if "Near", and "200000" if "Far", to get rid of the foggy effect.
 
  
<span id="Issue: Head clipping through hair"></span>
+
<span id="Issue: Character is suddenly invisible in both 1st and 3rd person views"></span>
=== Issue - Head clipping through hair ===
 
* Cause: FNV requires the vanilla hair meshes to be located in BSA archives to display properly. If you need to edit one of them, unpack it somewhere other than your Data directory.  If the problem is with custom hair styles, it is most likely that they were not made properly.
 
:* Solution: If you have "Data\Meshes\Characters\Hair" and "Head" folders, delete them and toggle "ArchiveInvalidation" so the game uses the files in the "Fallout - Meshes.BSA".
 
  
<span id="Issue: Interior cell portions not visible"></span>
+
===Issue - Character is suddenly invisible in both 1st and 3rd person views===
=== Issue - Interior cell portions not visible ===
+
Upon opening a save, the player character is suddenly invisible except for their shadow.  NPCs act like the character is present.  Loading an earlier save doesn't have the problem.
You may find some things invisible, not rendered, or apparently "transparent walls" in some interior cells; without ENB or other "post processor" installed or active.
+
 
 +
* Cause: Unknown, but might be related to use of the game "Auto-Save" feature.
 +
 
 +
:* Solution:  In the game console (default toggle key "~") enter the following commands (where "14" is the [http://fallout.wikia.com/wiki/Fallout:_New_Vegas_characters RefID of the player]):
 +
::<pre>
 +
::: prid 14
 +
::: enable
 +
</pre>
 +
:: and close the console.
  
*Cause: Mod conflict with more than one attempting to modify the same interior cell.  Often this is done by an author "copying" the interior cell and making changes without taking proper precautions regarding optimizations.  See the '''GECK''' [[#TIP: Enable "MultiBounds"|TIP: Enable "MultiBounds"]] for details.
+
<span id="Issue-WonkyTextures"></span>
:* Solution-1: You may want to experiment with changes to the "interior buffer size" setting. Start small, as the memory has to come from that used elsewhere.  Please see the "[http://www.tweakguides.com/Fallout3_10.html Memory, Loading & Multi-threading]" entry in the TweakGuides.com "Fallout 3 Tweak Guide".
+
=== Issue - Chinese Assault Rifle Textures are '''''wonky''''' ===
 +
: Thanks to '''XP47JSuperbolt''' of the Nexus Fallout "Mod Troubleshooting" forum for the basis of the following:
 +
* Cause: "Project Nevada" appears to cause a texture problem with the "Chinese Assault Rifle".
 +
:* Solution: Strangely, installing one of the [http://www.nexusmods.com/newvegas/mods/64339?tab=files Asurah Reanimation Pack] "Iron Sight Fix" files resolves the conflict.
  
:* Solution-2: The problem in the offending plugin has to be resolved by the author.  In the meantime, you have to identify the offending plugin(s) and remove from your "load order".  Please see the '[http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice#Clean_Saves Clean Saves]' section of the wiki "[http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice FNV General Mod Use Advice]" article.

:: See also [[#Issue_-_Followers_not_moving_or_Navmesh_Problems|Issue - Followers not moving or Navmesh Problems]] entry under the "Miscellaneous Solutions" section.
+
===Issue - Disable Map Markers===
 +
Desire to remove visible map markers in a mod that appear before the site has actually been visited.
 +
* Cause: The map marker in '''GECK''' (an "M" in a box with a large circle around an area in the Render window) has been flagged as "visible".
 +
:* Solution-1: This is much easier with [http://www.nexusmods.com/newvegas/mods/34703/? FNVedit] if you apply a filter to only show "map markers".
 +
::* Start '''FNVEdit''' and load your current load order (selected by default).
 +
::* When it's done loading, right-click somewhere in the left panel and select "Apply Filter".
 +
::* In the "Filter" dialog, check the option titled "Base Record EditorID contains" and in the field below it type "MapMarker".
 +
::* Confirm by pressing "Filter" and wait for a minute or two while the program is working.
 +
::* Find the map marker you want to disable.
 +
::* Find the "Record Flags" sub-record (in the right panel, almost at the top). Right-click the sub-record and select "Edit".
 +
::* At this point you may be introduced to a warning. Accept it.
 +
::* When the "Edit Value" dialog pops up, check the "Initially disabled" option and press "OK".
 +
::: The sub-record is now shown with a bold font, indicating that it has been modified.
 +
:: If the map marker is in "FalloutNV.esm" or one of the official DLC, you need to save your change as an "override" in a '''new plugin'''. It may also be prudent to avoid modifying mod plugin files directly unless you fully grasp the consequences of the changes you're making. Saving your change to a '''new plugin''' makes it easy to revert.
 +
::* Right-click the record and select "Copy as override into...".
 +
::* In the dialog that opens, select "<new file>" and enter a name for your new plugin.
 +
::: Selecting the record will now also list the override from your new plugin in the right panel.
 +
::* Proceed from step 6 (Find the "Record Flags" sub-record ...) in the previous set of instructions, but apply them to the record in your new plugin.
 +
::* When you're all done, close the '''FNVEdit''' program. You will see a list of all the plugins that has been modified in your current session. If a plugin is listed that you did not intentionally modify, deselect it. Press OK to save your changes and close '''FNVEdit'''.
  
<span id="Issue: Invisible Companion"></span>
+
:* Solution-2: Click on the marker in '''GECK''' to bring up it's "reference" interface window (see [http://geck.bethsoft.com/index.php?title=Reference GECK: Reference] page), and then check it as "initially disabled" so the marker will only appear when you actually discover the location.  Then click the "OK" button, and save the file.
  
=== Issue - Invisible Companion ===
+
:* Solution-3: If you wish to unset the "visible" flag (in the "Marker Data" section of the [http://geck.bethsoft.com/index.php?title=Reference GECK: Reference] window) instead of disabling the marker, that can be done in "FNAM - Flags" (near where the name and location type is also defined.) If the visible flag is set, it'll be listed below and you can right-click the entry and select "remove" to unset it.
A companion has suddenly gone "invisible" in the game, and nothing seems to make them visible againTheir marker appears on the Pipboy map, but they do not seem to physically be there upon traveling to that location.
 
  
* Cause: Unknown, but the situation has been reported to occur before.
+
<span id="Issue: Distant terrain/LOD flickers rapidly"></span>
:* Solution-1a: Load an earlier save from before they disappeared to obtain the companion's "Ref-ID".
 
::* Travel to the companion's location so your character is near them.
 
::* Open the in-game console (default is the < ~ > key).
 
:::* < Click > on the companion. This is all that is needed. Note this will display an 8 character "Ref-ID" above them, which you will need to remember.
 
::* Enter the console command: "prid <Ref-ID>" and < Enter >, but without the quotes (where "Ref-ID" is what you noted for the companion in the previous step).
 
::* Now enter: "disable" and < Enter >.
 
::* Follow with "enable" and < Enter >.
 
:: This sequence should make the companion visible again.
 
  
:* Solution-1b: Revert to using the earlier save from prior to their disappearance.
+
=== Issue - Distant terrain or LOD flickers rapidly ===
 +
This problem seems to occur more frequently with high-end systems, but across all sorts of platforms and video cards.
 +
* Cause: Known as "Z-fighting" or "stitching", this is a complex problem in 3D rendering where two or more "primatives" such as "layers" have similar or identical values in the "z-buffer", so they essentially occupy the same space.  The result is the pixels from each layer "fight" to be the one displayed on screen, especially when the point of view changes.  This causes a flickering, noisy display of first one then another color pixel.  See the "[https://en.wikipedia.org/wiki/Z-fighting Z-fighting]" article from Wikipedia for the full technical description.
  
:* Solution-1c: If "Solution-1a" doesn't work and "Solution-1b" is not really feasible and you prefer to live with the consequences, try "resurrecting" the companionThey may end up without their current inventory: losing everything you gave them to carry and reverting to their starting equipmentIt might also interfere with some of their quests as well, which is why it's the least preferred solution. Follow the same basic process with the commands:
+
* Solution: There is no single solution that applies to every system, and some of these effects cannot be resolved by the player.  See the S.T.E.P. Project Guide [http://wiki.step-project.com/Guide:Z-Fighting Z-Fighting] for examples of the issue and some INI tweaks that may help.  An FNV user tried some similar suggested in [https://www.youtube.com/watch?v=XjHt-4Z6PwI Gopher's "Mountain Flicker and Z-Fighting" video] and had the most success with adjusting the "fNearDistance=" value under [Display] in the "FalloutPrefs.INI" fileHe reports that anything above "10" results in clipping with arms and weapons in first person mode, but a balance can be reached with some testing.

=== Issue - Missing textures or walls ===
+
=== Issue - Entering an Interior spawns the player in a huge ball of items and NPCs ''aka '''junkado''''' or '''''junknado''''' ===
Entering some locations (e.g. "Hidden valley bunker", "Kings school", and "Camp Golf") the wallsappear to be transparent or missing, allowing aview of some elements of the adjacent interior rooms.  Collision still seems to be functioning (the character doesn't fall thorough the "gray areas" if they are enetered).
+
Also sometimes referred to as a "vortex on junk" or "compacting of cell contents".
  
* Cause: Mod conflict
+
* Cause-1: This has been traced to a corrupt ESM plugin from the mod [http://www.nexusmods.com/newvegas/mods/50817/? CAM - Chems Alcohol and Meds] by '''SenterPat'''.
:* Solution: The plugin "PrnOut.esp" (apparently a component of the "Sexout" mod) seems to be at least one culpritDeactivating it has been reported to correct the issue.
+
:* Solution-1: The problem has been fixed in version 9 of the mod.  Apparently it was resolved by removing the internal file header "ESM" flag from the ESP file.
 +
* Cause-2: File "FINAL Searchlight Airport NCR.esm" in mod [http://www.nexusmods.com/newvegas/mods/40324 Searchlight Airport NCR or Legion].  To put it simply, this mod makes a few minor adjustments in the "Camp Forlorn Hope Messhall" cell, which wouldn't be an issue except it moves one of the decals to something like (-3000) under the cell. No idea why the game responds this way, but the result is that the decal inexplicably pulls everything not nailed down along with it. Its like a powerful electromagnet dragging everything along the ground.
 +
:* Solution-2a: Thanks for '''Merik2013''' for diagnosing the source and solution to the problem.  He simply reset that decal back to its default settings and everything went back to normal. You probably could also just delete it from that ESM as well.  As always, make backups of the mods before editing.
 +
::* The cell is '''CampForlornHope01''' and the decal is ''NVNCRDecalCLeg''. You'll want to right click the decal and click the "edit" option.
 +
::* Its the Z Position that needs to be changed. He changed it to its default value, which is 671.1060. Also disabled (unchecked) all the miscellaneous changes made to it just to be sure it took, but that might not be necessary. The changes the mod made were enabling the "Persistent Reference" and "Initially Disabled" options as well as the "Flags: Set Enable State to Opposite of Parent " option under the "Enable Parent" tab(The last has also been suggested as a possible general fix to the problem on it's own.)
  
<span id="Issue: Mod makes the Sun too bright off surfaces"></span>
+
:* Solution-2b: Thanks to '''Roy Batty''' for the following:
=== Issue - Mod makes the Sun too bright off surfaces ===
+
::* Go into [http://www.nexusmods.com/newvegas/mods/34703/? FNVedit] and change the cleaning setting "set z -<some high number>" (ex: -3000) and TURN IT OFF.
Note this is not "sun glare", which is when you look directly at the sun in game.
+
::* Reclean your mod.
Be aware that there is a "light dome effect" around the New Vegas strip which is quite visible from a distance at night.  Daylight surfaces within this dome area are blindingly bright from some angles on default settings.  This appears to be by design.
+
::: (Note this solution predates v4.x of '''FNVEdit''' which has replaced such settings with the "AutoClean" function.  Presumably this is implemented in that function but we lack reports on how effective it is for this purpose, which is why it is not the primary solution.)
  
* Cause-1: Lighting mods make adjustments to various lighting values, resulting in uncomfortably bright reflections off some surfaces. Sometime these are by way of tweaks to the INI file, and sometimes controlled "in-game".
+
:* Solution-2c: Thanks to '''user826''' for experiments based upon the above "Solutions" leading to the following theory for mod creators:
 +
:: Placing (either deliberately or accidentally) "objects" (to include '''GECK''' things with "collision": like "trigger box activators") outside the "havok range boundary" of a cell seems to cause the "junknado".  (While this seems to occur in the "z-axis" most commonly, there is nothing to suggest so far this cannot occur when exceeding that boundary along any axis.)  The following warning about "accidental placement" is found in the [http://geckwiki.com/index.php?title=Bethsoft_Tutorial_Optimization Bethsoft Tutorial Optimization] article on '''GECKWiki''':
 +
<blockquote>
 +
    WARNING: Havok physics and the [http://geckwiki.com/index.php?title=Markers room markers] do not play well together. Avoid placing Havokable objects [to include [http://geckwiki.com/index.php?title=Movable_Static movable statics]] near [http://geckwiki.com/index.php?title=Room_Bounds_and_Portal_Basics portals] that they might be knocked through. [If an object is in, say, room A, then drawing of that object is restricted to people who are in room A, or who can see the object through a '''portal''' to room A. If the Havok engine causes the object to move (because the player picked it up with the Z key, or an explosion threw it) then the object will continue to be drawn so long as the object is in the motion under the control of the Havok system. However, once the object comes to rest, it is passed back to the normal renderer, and is once again drawn only for people in room A... even if it is now in room B. If you are in room B, with the object, it will be invisible to you.]
 +
</blockquote>
  
:* Solution-1a: Only use one lighting mod for exteriors, and one for interiors.  Read their documentation carefully for recommendations on where to position them in your load order.
+
* Cause-3: Some Weather mods cause this problem as a conflict in the interior cells of some mods.
:: Some mods intend you to use hats and sunglasses to mitigate the effect.  Changing the facing direction may also have an effect.
+
:* Solution-3If applying the "Solution-2a/2b" fixes above to either or both of the mod plugins in question fails to resolve the issue, try switching to a different Weather mod.
:: INI tweaks depend upon which surfaces and where they are located. See the [http://www.tweakguides.com/Fallout3_1.html Tweakguide's General Fallout game guide] (specifically for FO3 and FNV) for the effects of particular settings.
 
  
:* Solution-1b: The mod [http://www.nexusmods.com/newvegas/mods/51577/? Dynavision 3] incorporates (saving a plugin slot) [http://www.nexusmods.com/newvegas/mods/39619/? The Imaginator] which "allows you to separately control visual elements like Brightness, Contrast, Saturation, Light Output, Depth-of-Field, Focus, Motion Blur and Tint all from within an easy-to-navigate PIP-BOY menu". Dynavision 3 now works with UIO instead of requiring it's own installer.
+
<span id="Issue: Female Character strafing left modelling glitch"></span>
:: This is a recommended alternative to ENB and other "post-processors".  However, Dynavision has a persistent and annoying bug which frequently causes NPCs to go invisible.  Some people recommend using the older "Dynavision 2" + "Imaginator" instead, but the same "invisible NPCs" bug was reported with it.  A patch file to fix this issue in "Dynavision 3" was posted in mid 2016, but there are no comments regarding how effective it is.
 
  
:* Solution-1c: INI Lighting tweaks.  The following is derived from the [http://www.tweakguides.com/Fallout3_7.html TweakGuides for Fallout]Page numbers refer to that document.
+
=== Issue - Female Character strafing left modelling glitch ===
::* [View Distance] (Page 7)
+
The left arm appears totally mangledOnly seems to affect female models, and persists even if the entire FNV game and "Users\<acct>\documents\My Games\FalloutNV" folders are deleted and re-installed with only vanilla files (no mods).
::: Specularity Fade: This slider controls how shiny reflective surfaces appear to be. In practice the only obvious impact of changing this setting is that some metallic objects will lose their shine.  However you can also manually adjust the value of this setting by editing the INI "fSpecularLODStartFade" variable, and if you want to disable specularity altogether, either to further boost performance, or if you believe the game world is too shiny, then see the "bDoSpecularPass" variable covered on page 9.
 
::* [Display] (Page 7)
 
::: Brightness: This gamma slider controls how bright or dark the overall screen image will be. Adjust it so that at night the image is visible but not washed out. It has no impact on performance, so set to suit your taste. If you need to increase gamma to be much brighter than the maximum on the slider allows (e.g. on very old monitors), see the "fGamma"-related variables on page 9.
 
  
:* Solution-1d: Sometimes "post-processors" like the ENB Series can compensate, though remember that these often impose a penalty upon your "frames per second" (FPS)The first resort in these cases is often choosing a different "preset", but if you want to adjust settings yourself, see the S.T.E.P. Project [http://wiki.step-project.com/Guide:ENBseries_INI ENBSeries INI Guide] page which "is intended as THE comprehensive reference to the functionality of all parameters found within enbseries.ini as it evolves." Suggest you start with the "[BLOOM]" and "[REFLECTION]" sections.
+
* Cause: Why the problem persists through a re-install is unknownHowever, the cause appears to be related to the "left movement" animations used.
:: The [http://www.overclock.net/t/1386086/guides-to-creating-and-customizing-your-enbs Guides to Creating and Customizing Your ENB's] thread is another ENB settings resource.
+
:* Solution: For at least one user this was "mitigated" (though not actually resolved) by downloading a "BnB" (Bouncing Natural Breasts) skeleton and copying the "left movement" animations located in that mod's "meshes\characters\_male\female" folder to that of the "Data" folder tree.
  
* Cause-2: Your monitor brightness/gamma is too high.

<span id="Issue: FPVCameraBug"></span>

=== Issue - First Person camera bug wearing Riot Armor family of gear ===
 +
There can be a problem with the mod [https://www.nexusmods.com/newvegas/mods/55334 New Vegas - Enhanced Camera] by '''LogicDragon''' when drawing a weapon (even bare hands) in "First Person View" while wearing Power Armor or Elite Riot Armor in which half of the view is blocked by the left shoulder pauldron.
  
:* Solution-2: Use the [http://www.lagom.nl/lcd-test/ LCD monitor test images] web site as reference to adjust your monitor calibration to what you desire.
+
* Cause: This is due to a bug in the mod [http://www.nexusmods.com/newvegas/mods/51664 Yukichigai Unofficial Patch - YUP] that makes it so the Riot Armor family has its left shoulder appear in first person.  The source of the problem seems to be from YUP version 11.3 onwards (and possibly earlier versions.)  The YUP team is aware of the problem, but it has not been fixed as of version 11.7.  The same problem has also been referenced in the "Enhanced Camera" comments without attributing it to YUP.
  
<span id="Issue: Naked NPCs (missing armor or inventory)"></span>
+
:* Solution: Remove YUP from the load order.  As YUP provides many, many other bug fixes this is less than ideal and not recommended, but does resolve this particular problem.
=== Issue: Naked NPCs ''aka missing armor or inventory'' ===
 
* Cause: Vanilla Bug - Some NPCS are naked/have a weird inventory: An engine bug will sometimes not correctly refresh named and unnamed NPCsThe problem seems most often when they are supposed to be wearing leather armor.  (This appears to be a problem with "leveled lists".)
 
:* Solution-1: As always with any texture bug, try toggling "ArchiveInvalidation" off-and-on again.
 
  
:* Solution-2: Use/rebuild your "merged patch" file. Please see the 'Third Rule: The Rule of One' and 'Merge Patch File' sections of the wiki [http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice FNV General Mod Use Advice] article. Note that mods adding armor/clothing that is not appearing in-game may need to have the "bash tags" "Delev" and "Relev" added.
+
:* Partial Workaround:  The mod [http://www.nexusmods.com/newvegas/mods/65496 Elite Desert Combat Gear] offers a Desert Ranger Combat armor and helmet with the same stats as Elite Riot gear. The helmet is however still light armor to reflect the changes made by YUP.
  
:* Solution-3: Just open the console (default "<~>" key), click on the NPC and note it's displayed "Base-ID". Then type "resurrect <Base-ID>" (replacing "<Base-ID>" with the value noted when you clicked on the NPC). The NPC will be correctly refreshed with its gear.  If that doesn't work, try "resetinventory <Base-ID>".

=== Issue - Fisheye lens effect in 3rd Person ===
=== Issue - NPCs making annoying SHHHH sound and hand gesture ===
+
Both FO3 and FNV have a horrible "fisheye lens" effect with the default of 75 or higher in 3rd Person "Field of View" (FoV).  This affects what can be seen in the HUD, especially distorting items at the edges.
Some NPCs in the game, such as General Oliver & the Holograms & Dean Domino (when you meet him in the theater in Dead Money DLC), make that annoying SHHHH sound & hand gesture.
+
 
 +
* Cause: The problem lies with the way the game is displaying the image. For screenshots modders and imageshare users tend to greatly reduce the FoV to correct the problem, sometimes going as low as 30 or even 20.  The game is unplayable with the FoV this low; but it makes for better character screenshots.
 +
:* Solution: Use the "mouse wheel" to zoom the "chase camera" in or out as needed, or play around with the FoV using a mod such as [http://www.nexusmods.com/newvegas/mods/55085 FOV Slider].  However, note there are several different FoV settings and they have some impact upon each other.  The mods [http://www.nexusmods.com/newvegas/mods/36773 Further 3rd Person Camera] or [http://www.nexusmods.com/newvegas/mods/65521 Definitive Camera Hotkeys - a PHW Module] for normal game play may also help.

===Issue - Floating objects===
 +
Some objects in a cell "float" above ground level.
 +
* Cause: More than one plugin is changing the same thing, causing a record level conflict.
 +
* Solution-1: Use a "compatibility patch" file to resolve the record conflict.  See the [http://tesalliance.org/forums/index.php?/tutorials/article/28-oblivion-creating-compatibility-patches/ Oblivion: Creating Compatibility Patches - Worldbuilding - TES Alliance] article for basic guidance on creating one.
 +
* Solution-2: Edit each floating object in the "console window" (typically toggled with the "~" key), and then save the game.  The result would persist from that save game point onwards.  However it will re-appear if an earlier save were loaded, or a new game started, or a new mod added which also conflicts: so it is only a temporary solution to that specific conflict.  The edit would consist of:
 +
:* Click on the floating object.
 +
::* Use the "getpos [x|y|z]" commands, where "x"= is the '''horizontal''', "y" is the '''vertical''', and "z" is 'the '''height''' above the water table (AKA "ground level")' axis location in the cell.  Each axis must be retrieved individually, i.e. "getpos x", "getpos y", and "getpos z".  Record each result.
 +
::* Use the "getangle [x|y|z]" commands in the same manner.  Record each result.
 +
::* Use the "setpos z 0.00" command to reset the height of the object to "ground level".  Note the floating decimal number value.
 +
:: The record of "getpos" and "getangle" entries will enable you to restore things with the appropriate "setpos" or "setangle" commands if anything goes wrong.
 +
:* Repeat the above steps for each floating object as needed.
 +
:* Make a "full save" to a new "save game" slot.
 +
 
 +
<span id="Issue: Fog effect around the Vegas Strip"></span>
 +
=== Issue - Fog effect around the Vegas Strip ===
 +
* Cause: The area around New Vegas (outside the strip itself) uses the "NVWastelandHazy" weather type which includes the same effect that the distance fog does, but it's set as if the distance is nothing (-10) causing it to be present right where you are. Apparently it's there to give everything a sort of dirty/dusty appearance, as if lots of sand and dirt has been kicked up by the amount of human activity around Vegas.  The weather that does that nasty looking fog is "NVUrbanClear [WTHR:00173564]".
 +
:* Solution: Forcing the weather from "NVUrbanClear [WTHR:00173564]" to "NVWastelandHazy [WTHR:00100A4E]" will remove the fog.  "NVWastelandClear [WTHR:000FFC88]" doesn't "fog".
 +
:: Looking at NVUrbanClear, it has '''FNAM - Fog Distance''' Day & Night "- Near fog" set to "-10". ("NVWastelandClear" does as well), although during the night time it doesn't fog your eyes.
 +
:: So essentially to get rid of the fog using '''xEdit/'''[http://www.nexusmods.com/newvegas/mods/34703/? FNVedit], you would expand the "Weather" '''Object''' category, select "NVUrbanClear", and then scroll down to "FNAM - Fog Distance" and change "Night - Near" from "-10" to "2000"; and also for "NVWastelandClear" change both "Night - Near" and "Day - Near" from "-10" to "2000". Any Fog setting that is "-10" should be set to "2000" if "Near", and "200000" if "Far", to get rid of the foggy effect.

<span id="Issue: Head clipping through hair"></span>
 +
 
 +
=== Issue - Head clipping through hair ===
 +
* Cause: FNV requires the vanilla hair meshes to be located in BSA archives to display properly. If you need to edit one of them, unpack it somewhere other than your Data directory.  If the problem is with custom hair styles, it is most likely that they were not made properly.
 +
:* Solution: If you have "Data\Meshes\Characters\Hair" and "Head" folders, delete them and toggle "ArchiveInvalidation" so the game uses the files in the "Fallout - Meshes.BSA".
 +
 
 +
<span id="Issue: Interior cell portions not visible"></span>
 +
=== Issue - Interior cell portions not visible ===
 +
You may find some things invisible, not rendered, or apparently "transparent walls" in some interior cells; without ENB or other "post processor" installed or active.
 +
 
 +
*Cause: Mod conflict with more than one attempting to modify the same interior cell.  Often this is done by an author "copying" the interior cell and making changes without taking proper precautions regarding optimizations.  See the '''GECK''' [[#TIP: Enable "MultiBounds"|TIP: Enable "MultiBounds"]] for details.
 +
:* Solution-1: You may want to experiment with changes to the "interior buffer size" setting.  Start small, as the memory has to come from that used elsewhere.  Please see the "[http://www.tweakguides.com/Fallout3_10.html Memory, Loading & Multi-threading]" entry in the TweakGuides.com "Fallout 3 Tweak Guide".
 +
 
 +
:* Solution-2: The problem in the offending plugin has to be resolved by the author.  In the meantime, you have to identify the offending plugin(s) and remove from your "load order".  Please see the '[http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice#Clean_Saves Clean Saves]' section of the wiki "[http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice FNV General Mod Use Advice]" article.

<span id="Issue: Invisible Companion"></span>
 +
 
 +
=== Issue - Invisible Companion ===
 +
A companion has suddenly gone "invisible" in the game, and nothing seems to make them visible again.  Their marker appears on the Pipboy map, but they do not seem to physically be there upon traveling to that location.
 +
 
 +
* Cause: Unknown, but the situation has been reported to occur before.
 +
:* Solution-1a: Load an earlier save from before they disappeared to obtain the companion's "Ref-ID".
 +
::* Travel to the companion's location so your character is near them.
 +
::* Open the in-game console (default is the < ~ > key).
 +
:::* < Click > on the companion. This is all that is needed. Note this will display an 8 character "Ref-ID" above them, which you will need to remember.
 +
::* Enter the console command: "prid <Ref-ID>" and < Enter >, but without the quotes (where "Ref-ID" is what you noted for the companion in the previous step).
 +
::* Now enter: "disable" and < Enter >.
 +
::* Follow with "enable" and < Enter >.
 +
:: This sequence should make the companion visible again.
 +
 
 +
:* Solution-1b: Revert to using the earlier save from prior to their disappearance.
 +
 
 +
:* Solution-1c: If "Solution-1a" doesn't work and "Solution-1b" is not really feasible and you prefer to live with the consequences, try "resurrecting" the companion.  They may end up without their current inventory: losing everything you gave them to carry and reverting to their starting equipment.  It might also interfere with some of their quests as well, which is why it's the least preferred solution.  Follow the same basic process with the commands:
 +
::* "prid <Ref-ID>"
 +
::* "kill"
 +
::* "resurrect"
 +
::* "disable"
 +
::* "enable"
 +
:: This may require you to "re-hire" the companion and reset it's "companion command options".
 +
 
 +
<span id="Issue: InvisibleCorpses"></span>
 +
=== Issue - Invisible Corpses ===
 +
Symptoms: Any type of preplaced corpses in game (regardless if it's from primary ESMs for the game, edited ones, or even entirely new preplaced corpses from mods) turn entirely invisible and have no physical form to interact with, but can still be opened/searched as a container.
 +
 
 +
* Cause: The mod [https://www.nexusmods.com/newvegas/mods/66514?tab=description Slow Death] (file "(Animation)_Slow_Death.esp") has been confirmed to be at least one cause.
 +
:* Solution:  Remove the mod.  (It has been suggested the likely culprit for this issue is the 'SlowDeathBEScript' script, but not confirmed.)  This mod is based upon another ([http://www.nexusmods.com/newvegas/mods/60201 Near Death]) which might serve as an alternative.
 +
 
 +
<span id="Issue: LightingExteriors"></span>
 +
 
 +
=== Issue - Lighting - Exteriors at night ===
 +
Symptoms: Walls and ground textures seem to strangely disappear and re-appear from close view at night.  This might appear to be due to a missing or fading texture.
 +
 
 +
* Cause: FNV has a known "lighting problem " due to the game engine being limited to a maximum of 4 lights per exterior cell.  This causes lights suddenly disappearing, terrain not lighting properly, random polygons going unlit, etc..
 +
:* Solution: The mod [https://www.nexusmods.com/newvegas/mods/69833 Improved Lighting Shaders] fixes the shading code to work with up to 13 light slots, and also includes 28 re-assembled shaders that make full use of them.<br>
 +
:: In other words this pretty much gets rid of the lighting bug, and your Pip-Light can shine brightly without interfering with other lights!<br>
 +
:: Lights besides the Pip-Light are also improved: no more lights disappearing/reappearing depending on your camera position, or lines appearing when a light crosses cells - lights will now almost always remain lit if they're active!<br>
 +
:: ENB Users: Please note the "sticky" at the top of the comments page.
 +
 
 +
=== Issue - Lighting - Mod makes the Sun too bright off surfaces ===
 +
[Formerly "Issue - Mod makes the Sun too bright off surfaces".]
 +
 
 +
Symptom: Note this is not "sun glare", which is when you look directly at the sun in game.
 +
Be aware that there is a "light dome effect" around the New Vegas strip which is quite visible from a distance at night.  Daylight surfaces within this dome area are blindingly bright from some angles on default settings.  This appears to be by design.
 +
 
 +
* Cause-1: Lighting mods make adjustments to various lighting values, resulting in uncomfortably bright reflections off some surfaces.  Sometime these are by way of tweaks to the INI file, and sometimes controlled "in-game".
 +
 
 +
:* Solution-1a: Only use one lighting mod for exteriors, and one for interiors.  Read their documentation carefully for recommendations on where to position them in your load order.
 +
:: Some mods intend you to use hats and sunglasses to mitigate the effect.  Changing the facing direction may also have an effect.
 +
:: INI tweaks depend upon which surfaces and where they are located.  See the [https://web.archive.org/web/20161025065631/http://www.tweakguides.com/Fallout3_1.html Tweakguide's General Fallout game guide] (specifically for FO3 and FNV) for the effects of particular settings.
 +
 
 +
:* Solution-1b: The mod [http://www.nexusmods.com/newvegas/mods/51577/? Dynavision 3] incorporates (saving a plugin slot) [http://www.nexusmods.com/newvegas/mods/39619/? The Imaginator] which "allows you to separately control visual elements like Brightness, Contrast, Saturation, Light Output, Depth-of-Field, Focus, Motion Blur and Tint all from within an easy-to-navigate PIP-BOY menu". Dynavision 3 now works with UIO instead of requiring it's own installer.
 +
:: This is a recommended alternative to ENB and other "post-processors".  However, Dynavision has a persistent and annoying bug which frequently causes NPCs to go invisible.  Some people recommend using the older "Dynavision 2" + "Imaginator" instead, but the same "invisible NPCs" bug was reported with it.  A patch file to fix this issue in "Dynavision 3" was posted in mid 2016, but there are no comments regarding how effective it is.
 +
 
 +
:* Solution-1c: INI Lighting tweaks.  The following is derived from the [https://web.archive.org/web/20161025065631/http://www.tweakguides.com/Fallout3_7.html TweakGuides for Fallout].  Page numbers refer to that document.
 +
::* [View Distance] (Page 7)
 +
::: Specularity Fade: This slider controls how shiny reflective surfaces appear to be. In practice the only obvious impact of changing this setting is that some metallic objects will lose their shine.  However you can also manually adjust the value of this setting by editing the INI "fSpecularLODStartFade" variable, and if you want to disable specularity altogether, either to further boost performance, or if you believe the game world is too shiny, then see the "bDoSpecularPass" variable covered on page 9.
 +
::* [Display] (Page 7)
 +
::: Brightness: This gamma slider controls how bright or dark the overall screen image will be. Adjust it so that at night the image is visible but not washed out. It has no impact on performance, so set to suit your taste. If you need to increase gamma to be much brighter than the maximum on the slider allows (e.g. on very old monitors), see the "fGamma"-related variables on page 9.
 +
 
 +
:* Solution-1d: Sometimes "post-processors" like the ENB Series can compensate, though remember that these often impose a penalty upon your "frames per second" (FPS).  The first resort in these cases is often choosing a different "preset", but if you want to adjust settings yourself, see the S.T.E.P. Project [http://wiki.step-project.com/Guide:ENBseries_INI ENBSeries INI Guide] page which "is intended as THE comprehensive reference to the functionality of all parameters found within enbseries.ini as it evolves."  Suggest you start with the "[BLOOM]" and "[REFLECTION]" sections.
 +
:: The [http://www.overclock.net/t/1386086/guides-to-creating-and-customizing-your-enbs Guides to Creating and Customizing Your ENB's] thread is another ENB settings resource.
 +
 
 +
* Cause-2: Your monitor brightness/gamma is too high.
 +
 
 +
:* Solution-2: Use the [http://www.lagom.nl/lcd-test/ LCD monitor test images] web site as reference to adjust your monitor calibration to what you desire.
 +
 
 +
<span id="Issue: Missing textures/walls"></span>
 +
 
 +
=== Issue - Missing textures or walls ===
 +
Entering some locations (e.g. "Hidden valley bunker", "Kings school", and "Camp Golf") the walls appear to be transparent or missing, allowing a view of some elements of the adjacent interior rooms.  Collision still seems to be functioning (the character doesn't fall through the "gray areas" if they are entered).
 +
 
 +
* Cause: Mod conflict
 +
:* Solution: The plugin "PrnOut.esp" (apparently a component of the "Sexout" mod) seems to be at least one culprit.  Deactivating it has been reported to correct the issue.
 +
 
 +
<span id="Issue: Mod makes the Sun too bright off surfaces"></span>
 +
 
 +
<span id="Issue: Naked NPCs (missing armor or inventory)"></span>
 +
 
 +
=== Issue: Naked NPCs ''aka missing armor or inventory'' ===
 +
* Cause: Vanilla Bug - Some NPCS are naked/have a weird inventory: An engine bug will sometimes not correctly refresh named and unnamed NPCs.  The problem seems most often when they are supposed to be wearing leather armor.  (This appears to be a problem with "leveled lists".)
 +
:* Solution-1: As always with any texture bug, try toggling "ArchiveInvalidation" off-and-on again.
 +
 
 +
:* Solution-2: Use/rebuild your "merged patch" file.  Please see the 'Third Rule: The Rule of One' and 'Merge Patch File' sections of the wiki [http://wiki.nexusmods.com/index.php/FNV_General_Mod_Use_Advice FNV General Mod Use Advice] article.  Note that mods adding armor/clothing that is not appearing in-game may need to have the "bash tags" "Delev" and "Relev" added.
 +
 
 +
:* Solution-3: Just open the console (default "<~>" key), click on the NPC and note it's displayed "Base-ID". Then type "resurrect <Base-ID>" (replacing "<Base-ID>" with the value noted when you clicked on the NPC). The NPC will be correctly refreshed with its gear.  If that doesn't work, try "resetinventory <Base-ID>".
 +
 
 +
<span id="Issue: NPCs making annoying SHHHH sound and hand gesture"></span>
 +
=== Issue - NPCs making annoying SHHHH sound and hand gesture ===
 +
Some NPCs in the game, such as General Oliver & the Holograms & Dean Domino (when you meet him in the theater in Dead Money DLC), make that annoying SHHHH sound & hand gesture.
 +
 
 +
* Cause: This has been traced to the mod [http://www.nexusmods.com/newvegas/mods/43386 Axepriests Face Aches for FNV] by '''SariDecember''', which is a port of the FO3 mod [http://www.nexusmods.com/fallout3/mods/6709 FAFF - Face Aches For Fallout] by '''Axepriest''' (who hasn't been active on Nexus since Feb 2016).  This adds facial expressions to idle animations ("*.kf" files).
 +
:* Solution: The mod is designed only to work with vanilla head meshes and textures, adding "morphs" which reference the data built into the FaceGen TRI files.  (See the "[[Getting_started_creating_mods_using_GECK#FaceGen:_Heads.2C_Faces.2C_Hairs.2C_and_Helmets|FaceGen: Heads, Faces, Hairs, and Helmets]]" section of the wiki "[[Getting_started_creating_mods_using_GECK|Getting started creating mods using GECK]]" article.)  Either remove the mod, or refer to the FNV and FO3 mod descriptions to attempt to change the morphs associated with the idle animation in question.
 +
 
 +
<span id="Issue: PermanentLimp"></span>
 +
=== Issue - Permanent Limp ===
 +
Symptoms: the Player displays a limp even after having been healed of damage.<br>
 +
If it's an animation, then it's a 'feature' of the game (or some mod); not a bug.  It indicates the Actor has broken a limb.  If it "heals" without the proper treatment, it becomes "permanent".
 +
 
 +
* Cause: With the legs, it's typically from a fall from a height or critical hit to the leg.
 +
 
 +
:* Solution: You need to heal the limb with a "doctor's bag" (which contains a "splint") or by an actual doctor before saving.  (Just healing damage with Stimpacks, etc. won't "set the break".)  Once it has gotten in your "save game" files, it has (for some people) been fixable by reloading the save file during the same "game session" (i.e. not exiting to the desktop).  Others found it necessary to go back to a save prior to the injury.
 +
 
 +
<span id="Issue: Pink teeth/tongue/mouth"></span>
 +
 
 +
=== Issue - Pink teeth or tongue or mouth ===
 +
* Cause: This is another "missing texture file" problem, usually because of failing to allow overwrite of a file during installation of the mod in question; sometimes by not actually making a choice of options.
 +
:* Solution: Uninstall the mod entirely from your mod manager (or the "Data" folder), close the manager and re-open, and re-install the mod.  This time always make a choice to "overwrite" when offered unless you have very good reason to not do so (knowing it may cause problems with the mod).
 +
 
 +
<span id="Issue: Player hands are either stubs, too large, or the fingers are missing"></span>
 +
=== Issue - Player hands are either stubs or too large or the fingers are missing ''AKA Fingers glitch'' ===
 +
* Cause: Fallout 3 and New Vegas have a bug when using ''iFPSClamp'' (in the game INI file), causing the hands of NPCs and the player to either become massive, or collapse into themselves.
 +
: This problem seems to also be linked to the "64Hz bug" fix for "microstutter" included in "New Vegas Stutter Remover" (NVSR) and "New Vegas Tick Fix" (NVTF).  The reason why the "64Hz bug" occurs is because the renderer uses ''GetTickCount'' which returns a variable frequency that jumps between 13-16ms, whereas ''TimeGetTime'' will consistently return a frequency of 1ms.  This is an "Unreal Engine" bug which persisted into 2015 (at least).
 +
: As both NVSR and NVTF use the same code for the "64Hz bug", the end result is that you can choose between having a microstutter and no "fingers glitch" or having no microstutter and fingers glitching out. 
 +
: There is no one reliable solution to the problem.  The following "mitigations" have helped people to different extents.
 +
 
 +
:* Mitigation-1: See also the related [[#Issue_-_Vsync_aka_V-Sync_ON_or_OFF|Issue - Vsync aka V-Sync ON or OFF]] regarding "frame rate synchronization", "screen-tearing", and "lag".
 +
::* The various "Borderless Window" or "Fake Fullscreen Window" mods (such as "[http://www.nexusmods.com/newvegas/mods/59266/? OneTweak for NVSE]" by virusek) may prevent Vsync issues if you don't have a triple buffered video card. 
 +
:* Mitigation-2: Setting "bManageFPS=0" in NVSR.INI, the "finger glitch" problem is gone, but then stuttering is back.
 +
:* Mitigation-3: Limit your FPS to 60.  If that doesn't help, try using a setting just below that (ie. 57-59).
 +
:* Mitigation-4: Manage your FPS setting in only one location (e.g. NVSR or the INI file, but not both).  If you do have to manage it in more than one location, then ensure you have the same cap in all setting locations.  (There are suggestions about this in the "Causes" under the [[#Issue_-_Game_in_slow_motion|Issue - Game in slow motion]] entry.) 
 +
:: Note there may be different settings for "maximum" and "minimum" FPS.  Setting a "minimum" below 30 causes the render engine into a "slow display mode".
 +
:* Mitigation-5: Others have reported that "drawing a two-handed weapon" or exiting to the desktop and re-loading the game save file have temporarily resolved the "fingers glitch" problem.
 +
:* Mitigation-6: Try a different video driver.
 +
::* Or, an alternative solution to a driver update: Grab [http://www.entechtaiwan.com/ps.htm Powerstrip] and follow simple instructions in [http://gfycat.com/MinorSilentArgusfish this GFY].

 +
<span id="Issue: Pip-boy and Terminal screens are all white/blank"></span>
 +
 
 +
=== Issue - Pip-boy and Terminal screens are all white or blank ===
 +
* Cause-1: This is a known game bug.
 +
:* Solution-1: Try toggling the Pip-boy light on and off a few times (hold down the < Tab > key for a few seconds) to see if it resolves the problem.
 +
 
 +
* Cause-2: A mod for the Pip-boy 3000 or attempts to optimize texture files have installed texture files causing the problem.
 +
:* Solution-2: Check the "Data\Textures" folder for a "Pip-boy 3000" sub-folder and if it exists, delete the sub-folder.  The game will then use the default files in the BSA.
 +
 
 +
<span id="Issue: Playing at greater than 1920x1080 resolution"></span>
 +
=== Issue - Playing at greater than 1920x1080 resolution ===
 +
* Cause: By default the game hardware setup options only permit a maximum of 1920x1080 resolution.  This is a factor due to it's age.  It simply didn't know what later advances in screen sizes would establish as standards.
 +
:* Solution-1: In the "FalloutPrefs.ini" file under the "[Display]" section (near the bottom) are two entries where you should specify your desired game screen size to match your default/native monitor resolution:
 +
<div name="Simulated code box" class="boilerplate metadata" id="Warning Notice"
 +
style="margin:0px 10px 10px 50px; border:1px dashed #DAA520; color: lightgray; background-color:#424242; padding:3px;
 +
/* Remove the next four 'white-space' lines to restore default white-space processing. */
 +
white-space: pre-wrap;      /* css-3 */
 +
white-space: -moz-pre-wrap;  /* Mozilla, since 1999 */
 +
white-space: -pre-wrap;      /* Opera 4-6 */
 +
white-space: -o-pre-wrap;    /* Opera 7+ */
 +
word-wrap: break-word;      /* Internet Explorer 5.5+ */
 +
">
 +
iSize W=<width in pixels> (i.e. 2560)
 +
iSize H=<height in pixels> (i.e. 1440)
 +
</div>
 +
:: However, these only work if you have the "bFullScreen=1" setting enabled so the game starts in "full screen" mode.  In "windowed mode", the game will revert back the maximum of 1920x1080 that it knows about.
 +
 
 +
:* Solution-2: If you prefer to run the game in "fake fullscreen windowed mode" so you can get to other programs or screens, then you need to use a setting of "bFullScreen=0" (windowed mode), along with the above "iSize" settings, AND a '''NVSE''' mod which handles the "fake fullscreen" effect while recognizing the larger screen resolutions.  NVSE knows and can read the INI setting and override the game.  These are reported to do so:

 +
::* [http://www.nexusmods.com/newvegas/mods/57843/? FullScreenWindowedMode] by '''TimThompson89'''.
 +
 
 +
:* Solution-3: If you are using a "post processor" such as ENB, make sure it is not adding some feature like "cinematic bars" to create an effect similar to "letter-boxing" of your display.
 +
 
 +

 +
 
 +
=== Issue - Scope zoom distortion problems ===
 +
Playing with widescreen (16:9) and high resolution (1920x1080 or higher) and have a problem with scope zooms (white square edges or just edges in the reticle and the scopes have an outstretched circle).
 +
* Cause: Game masking that is automatically applied to scopes.
 +
 
 +
* Solution:  add the line "fScopeScissorAmount=0", in the "[Display]" section of all 3 INIs.
 +
*: Make backups of the INIs before changing them.
 +
:: When you make any changes to the game INI file, remember to change it in all three files: the "Fallout_default.ini" in the game root folder (which only gets used to recreate the other two when they are not found), and the two in "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV" folder ("FALLOUT.ini" and "FalloutPrefs.ini").  Otherwise you tend to lose track of which you actually changed if you have to "verify files", and they may not appear to "take".<br>

=== Issue - Screen brightness gets darker as the game progresses ===
 +
* Cause-1: Conflict between ENB and SweetFX settings.
  
* Cause: This has been traced to the mod [http://www.nexusmods.com/newvegas/mods/43386 Axepriests Face Aches for FNV] by '''SariDecember''', which is a port of the FO3 mod [http://www.nexusmods.com/fallout3/mods/6709 FAFF - Face Aches For Fallout] by '''Axepriest''' (who hasn't been active on Nexus since Feb 2016). This adds facial expressions to idle animations ("*.kf" files).
+
:* Solution-1: Identify the conflicting settings in the INI files and choose one.
:* Solution: The mod is designed only to work with vanilla head meshes and textures, adding "morphs" which reference the data built into the FaceGen TRI files.  (See the "[[Getting_started_creating_mods_using_GECK#FaceGen:_Heads.2C_Faces.2C_Hairs.2C_and_Helmets|FaceGen: Heads, Faces, Hairs, and Helmets]]" section of the wiki "[[Getting_started_creating_mods_using_GECK|Getting started creating mods using GECK]]" article.)  Either remove the mod, or refer to the FNV and FO3 mod descriptions to attempt to change the morphs associated with the idle animation in question.

<span id="Issue: Pink teeth/tongue/mouth"></span>
+
* Cause-2: Don't ignore your monitor's role.  Monitors are like TVs: they react to the ambient light levels in the roomDo not play in a completely dark room.
=== Issue - Pink teeth or tongue or mouth ===
 
* Cause: This is another "missing texture file" problem, usually because of failing to allow overwrite of a file during installation of the mod in question; sometimes by not actually making a choice of options.
 
:* Solution: Uninstall the mod entirely from your mod manager (or the "Data" folder), close the manager and re-open, and re-install the modThis time always make a choice to "overwrite" when offered unless you have very good reason to not do so (knowing it may cause problems with the mod).
 
  
<span id="Issue: Player hands are either stubs, too large, or the fingers are missing"></span>
+
:* Solution-2: You need a source of steady light level (a non-flourescent lamp) to prevent your monitor reacting to changing game light levels.
=== Issue - Player hands are either stubs or too large or the fingers are missing ''AKA Fingers glitch'' ===
 
* Cause: Fallout 3 and New Vegas have a bug when using ''iFPSClamp'' (in the game INI file), causing the hands of NPCs and the player to either become massive, or collapse into themselves.
 
: This problem seems to also be linked to the "64Hz bug" fix for "microstutter" included in "New Vegas Stutter Remover" (NVSR) and "New Vegas Tick Fix" (NVTF).  The reason why the "64Hz bug" occurs is because the renderer uses ''GetTickCount'' which returns a variable frequency that jumps between 13-16ms, whereas ''TimeGetTime'' will consistently return a frequency of 1ms.  This is an "Unreal Engine" bug which persisted into 2015 (at least).
 
: As both NVSR and NVTF use the same code for the "64Hz bug", the end result is that you can choose between having a microstutter and no "fingers glitch" or having no microstutter and fingers glitching out. 
 
: There is no one reliable solution to the problem.  The following "mitigations" have helped people to different extents.
 
  
:* Mitigation-1: See also the related [[#Issue_-_Vsync_aka_V-Sync_ON_or_OFF|Issue - Vsync aka V-Sync ON or OFF]] regarding "frame rate synchronization", "screen-tearing", and "lag".
+
:* Amelioration: A mod that gives you more control over lighting in-game: [http://www.nexusmods.com/newvegas/mods/39619/? The IMAGINATOR].  This might be useful to confirm some mod is the culprit, by loading it near the end/bottom of the LO.
::* The various "Borderless Window" or "Fake Fullscreen Window" mods (such as "[http://www.nexusmods.com/newvegas/mods/59266/? OneTweak for NVSE]" by virusek) may prevent Vsync issues if you don't have a triple buffered video card.   
 
:* Mitigation-2: Setting "bManageFPS=0" in NVSR.INI, the "finger glitch" problem is gone, but then stuttering is back.
 
:* Mitigation-3: Limit your FPS to 60.  If that doesn't help, try using a setting just below that (ie. 57-59).
 
:* Mitigation-4: Manage your FPS setting in only one location (e.g. NVSR or the INI file, but not both).  If you do have to manage it in more than one location, then ensure you have the same cap in all setting locations.  (There are suggestions about this in the "Causes" under the [[#Issue_-_Game_in_slow_motion|Issue - Game in slow motion]] entry.) 
 
:: Note there may be different settings for "maximum" and "minimum" FPS.  Setting a "minimum" below 30 causes the render engine into a "slow display mode".
 
:* Mitigation-5: Others have reported that "drawing a two-handed weapon" or exiting to the desktop and re-loading the game save file have temporarily resolved the "fingers glitch" problem.
 
:* Mitigation-6: Try a different video driver.
 
::* Or, an alternative solution to a driver update: Grab [http://www.entechtaiwan.com/ps.htm Powerstrip] and follow simple instructions in [http://gfycat.com/MinorSilentArgusfish this GFY].

 +
=== Issue - Somehow ''without changing anything'' my character is ''glitched'' oddly ===
 +
* Cause: Unknown.
 +
:* Workaround: Something that's always worth trying is blowing yourself up or otherwise get killed: i.e. throw a grenade against a wall so it bounces back and kills you.  Then let the game reload.  Sometimes that can clear oddities.  However, it doesn't address any underlying cause, so it's only useful as a temporary solution.  Try to see if you can reproduce a reliable set of circumstances to re-create the problem.
  
=== Issue - Pip-boy and Terminal screens are all white or blank ===
+
<span id="Issue: Textures randomly change only on particular items"></span>
* Cause-1: This is a known game bug.
+
=== Issue - Textures randomly change only on particular items ===
:* Solution-1: Try toggling the Pip-boy light on and off a few times (hold down the < Tab > key for a few seconds) to see if it resolves the problem.
+
* Cause: There is more than one BSA containing the named texture file, but they have different content.  The game does not have any mechanism to deal with this situation, so it randomly grabs the texture from one or the other BSA file.
 +
:* Solution-1: Try the simple solution of toggling "ArchiveInvalidation" off-and-then-on again.  This should cause any loose file to be used instead of one in a BSA.
  
* Cause-2: A mod for the Pip-boy 3000 or attempts to optimize texture files have installed texture files causing the problem.
+
:* Solution-2: Determine which mods have the different textures. See [[#Issue:_Find_the_source_mod-index_of_an_object_in-game|Issue: Find the source mod-index of an object in-game]].  Once you have identified the one with your preferred texture, either remove the other offending plugin or extract the preferred texture from the BSA as a "loose file", and toggle "ArchiveInvalidation".
:* Solution-2: Check the "Data\Textures" folder for a "Pip-boy 3000" sub-folder and if it exists, delete the sub-folder.  The game will then use the default files in the BSA.

+
<span id="Issue - TTW Centaur Face distortion"></span>
=== Issue - Playing at greater than 1920x1080 resolution ===
+
=== Issue - TTW Centaur Face distortion ===
* Cause: By default the game hardware setup options only permit a maximum of 1920x1080 resolution.  This is a factor due to it's age.  It simply didn't know what later advances in screen sizes would establish as standards.
+
When playing "Tale of Two Wastelands" (TTW) the Centaur face may appear to stretch off into the distance.
:* Solution-1: In the "FalloutPrefs.ini" file under the "[Display]" section (near the bottom) are two entries where you should specify your desired game screen size to match your default/native monitor resolution:
 
<div name="Simulated code box" class="boilerplate metadata" id="Warning Notice"
 
style="margin:0px 10px 10px 50px; border:1px dashed #DAA520; color: lightgray; background-color:#424242; padding:3px;
 
/* Remove the next four 'white-space' lines to restore default white-space processing. */
 
white-space: pre-wrap;      /* css-3 */
 
white-space: -moz-pre-wrap;  /* Mozilla, since 1999 */
 
white-space: -pre-wrap;      /* Opera 4-6 */
 
white-space: -o-pre-wrap;    /* Opera 7+ */
 
word-wrap: break-word;      /* Internet Explorer 5.5+ */
 
">
 
iSize W=<width in pixels> (i.e. 2560)
 
iSize H=<height in pixels> (i.e. 1440)
 
</div>
 
:: However, these only work if you have the "bFullScreen=1" setting enabled so the game starts in "full screen" mode.  In "windowed mode", the game will revert back the maximum of 1920x1080 that it knows about.
 
  
:* Solution-2: If you prefer to run the game in "fake fullscreen windowed mode" so you can get to other programs or screens, then you need to use a setting of "bFullScreen=0" (windowed mode), along with the above "iSize" settings, AND a '''NVSE''' mod which handles the "fake fullscreen" effect while recognizing the larger screen resolutions.  NVSE knows and can read the INI setting and override the game.  These are reported to do so:
+
Note: this is very similar to the problem with "B-n-B" bodies discussed under the [[#Issue_-_Body_Replacer_-_Custom_Body_Types|Issue - Body Replacer - Custom Body Types]] entry: having the same issue of differences in "bone attachment points" and "bone weighting".
::* [http://www.nexusmods.com/skyrim/mods/40706/? OneTweak] by '''virusek''' (from the Nexus Skyrim Catelog, but works with FNV.)
 
::* [http://www.nexusmods.com/newvegas/mods/57843/? FullScreenWindowedMode] by '''TimThompson89'''.
 
  
:* Solution-3: If you are using a "post processor" such as ENB, make sure it is not adding some feature like "cinematic bars" to create an effect similar to "letter-boxing" of your display.
+
* Cause: The TTW version 4.1 of the [http://www.nexusmods.com/newvegas/mods/59147? Ragdolls] mod version of the '''Evolved Centaur''' is missing modifications to the skeleton (armature) and mesh needed to fix dismemberments.  The author is aware of the problem, which will be fixed in releases after 4.1.  In the meantime he suggests the following "workaround".
  
:* You will probably want to see the [[#Issue: Scope zoom distortion problems|Issue: Scope zoom distortion problems]] entry as well.
+
:* Workaround "fix" for v4.1 (TTW): Install or unpack the Ragdolls TTW mod as usual, goto under the "meshes | creatures | centaur" folder, and delete "skeletonevolved.nif" file.  (You may want to repackage the "Ragdolls TTW" archive so that file is not later re-installed by accident.) Then toggle "ArchiveInvaliation" off-and-then-on again.

 +
Some visual effect (such as "Cateye", "HUD Shudder", or "chem" induced blur) won't wear off or go away.
  
=== Issue - Scope zoom distortion problems ===
+
* Cause: An "[http://geckwiki.com/index.php?title=ImageSpace_Modifier imagespace modifier]" (IMOD) remains in effect.
Playing with widescreen (16:9) and high resolution (1920x1080 or higher) and have a problem with scope zooms (white square edges or just edges in the reticle and the scopes have an outstretched circle).
+
:* Solution: The console command "[http://geckwiki.com/index.php?title=RemoveImageSpaceModifier rimod <imodID>]" will remove the specified IMOD.  The mod "[http://www.nexusmods.com/newvegas/mods/69096 Clear Imagespace Modifiers BAT file]" is a console "bat" file containing that command for all of the vanilla IMOD effects to clear them all at once.
* Cause: Game masking that is automatically applied to scopes.
 
  
* Solution:  add the line "fScopeScissorAmount=0", in the "[Display]" section of all 3 INIs.
+
<span id="Issue: Weapons/Fists are displayed off-center in 1st Person"></span>
*: Make backups of the INIs before changing them.
 
:: When you make any changes to the game INI file, remember to change it in all three files: the "Fallout_default.ini" in the game root folder (which only gets used to recreate the other two when they are not found), and the two in "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV" folder ("FALLOUT.ini" and "FalloutPrefs.ini").  Otherwise you tend to lose track of which you actually changed if you have to "verify files", and they may not appear to "take".<br>

 +
 +
* Cause: In the ''VCG01Test'' quest (the in-game code related to the psych eval) is the script that controls what happens as a result of the dialogue. The script has three skill pools, and guarantees a player gets at least 1 tagged "combat" pool skill and 1 tagged "gate-opener" pool skill. Among the "gate-opener" skills are ''Science, Lockpicking, Speech,'' and ''Barter''. Regardless of the other answer options you chose, you will get one of the skills from each of those two pools tagged if none were chosen.
 +
:* Solution:  Functioning as intended by the developers.  Use a "cheat" tool (such as  "[https://www.nexusmods.com/newvegas/mods/49152 Fallout NV Cheat Terminal Redux]") to change the result to what you want instead.

<span id="Issue: DamageBug"></span>
 +
=== Issue - MAIN - Weapon Damage displayed for other weapons is unexpected ===
 +
: Thanks to '''holyshitijustwantanaccount''' of the Nexus Fallout "New Vegas Mod Troubleshooting" forum for discovering the basis of the following:
 +
 +
Symptoms: When equipping a weapon (specifically noticed with a "shotgun"), the damage for all other Player weapons changes wildly until it is "unequipped".  This occurs even without any mods installed.
 +
 +
* Cause: (Thanks to '''miguick''' for investigating and providing this information.) This is vanilla game behavior.  The game displays the damage of all weapons adjusted by the ammo effects of your currently loaded ammo, even if those weapons don't use it. Since the default ammo for shotguns has something like a x1.2 damage multiplier, you'll see all other weapons adjusted by that much.
 +
 +
: So other than that annoyance when viewing weapons in the Pipboy and containers, it isn't much of a problem?  Well, it is, because it can also change the damage and effects of things like mines you've laid that go off while you have that ammo loaded.  Which means that if you have "bean bags" loaded, a mine you laid will deal 5% damage and will cause '''fatigue''' like a "bean bag" impact.  And with HP ammo loaded: a mine will deal 175% damage, but then faces a x3 DT increase in whatever it harms in the blast, etc.  It's affected by any current ammo you have.  Most of the time it's "cosmetic" but the game treats all damage you cause as affected by your current ammo's effects behind the scenes, which under normal circumstances would only come into play when mines are involved, but the problem is still real.
 +
 +
:* Solution: Vanilla behavior.  Not a mod conflict.  Not previously identified or "corrected" by any mod.  (People didn't notice it over the last decade, so why worry about it now just because "you know"?  The good news is that an experienced modder has become motivated to look into fixing it.)

=== Issue - All Scripts Recompiled Warning ===
 +
: Thanks to '''wfandrews''' and '''LStewieAL''' of the Nexus "New Vegas Technical Support Forum" for identifying and investigating this issue.
 +
: Symptoms: A "Command Prompt" Window appears to flash briefly with the message:<br>
 +
<p style="margin:0px 10px 10px 30px; color: red; background-color:#fff5f5;">"Warning!<br>
 +
< some plugin name > has recompiled all scripts. This is dangerous to your save game. Quit and remove the mod from your load order or clean it of ITMs using [http://www.nexusmods.com/newvegas/mods/34703/? FNVedit]."</p>
 +
: This message may also appear in a NVSE logfile.
 +
 +
* Cause: The warning has been confirmed to be from "[https://www.nexusmods.com/newvegas/mods/66347 lStewieAl's Tweaks]" versions 5.20 and later.  It is based upon detecting the named plugin is overwriting two unused vanilla scripts no mod should be touching, which are used to determine this is the likely condition.
 +
 +
: When someone uses the GECK Script Editor command to "recompile all scripts", it causes EVERY script currently loaded into the GECK (all from vanilla and DLC and any mods) to be recompiled and included in the modified plugin which is currently "active".  While that might initially seem to not be a "bad thing", it means that every other identical preceding loaded script file (including those of the vanilla game) gets overridden by that plugin and will cause problems as those scripts will now have the ''mod index'' of the modified plugin instead of the originals, which will cause errors for everything referencing them.  The problem won't be within that mod, but in everything else: breaking them all.  NO MOD AUTHOR SHOULD USE THIS COMMAND but many are not aware of why.  There is no internal GECK warning associated with the command.

=== Issue - Dying with red TMP displayed ===
 +
Symptoms: The letters "TMP" have appeared in red on the right hand of the HUD screen.  Every time this occurs, character loses 5 or 6 HP.  Also, keeps getting sleep deprivation even though "Hardcore mode" is not on.
 +
 +
* Cause: The mod "[https://www.nexusmods.com/newvegas/mods/35998 Nevada Skies - Weather Effects]" prior to version "Final" (04 Oct 2020) had a feature called "Frostfall" that could be enabled in the "Mod Configuration Menu (MCM)". The "Frostfall" setting adds a 'heat stroke'/hypothermia function to the game; switching on "Hardcore Mode" in the process (even if it says it's off in the settings menu).
 +
:: "TMP" = Temperature
 +
: The "Frostfall" feature was cut because it was never finished and the author has stopped working on the mod.
 +
 +
:* Solution:  Shut off the "Frostfall" setting in the MCM, or upgrade to the "Final" version which removes the feature.

You are looking for the "record-ID", "Editor-ID" or "Base-ID" in "hexadecimal" number format for each record (row) in the plugin in question.  The "record number" consists of a "mod index" and it's sequential position within the plugin.  (Please see the short article [http://fallout.wikia.com/wiki/Help:Form_IDs Help:Form IDs] on how to interpret the "mod index".)  The "Editor-ID" is the "human readable" name for that record, while the "Base-ID" is that of the "template Form-ID" each specific "Reference-ID" copy placed in the "game world" is based upon.  The "vanilla" ones provided by the base game and DLCs can be found on the [http://fallout.gamepedia.com/Fallout_Wiki The Vault] and [http://fallout.fandom.com/wiki/Portal:Fallout:_New_Vegas  Nukapedia] wikis in the page describing each.  Please see the [http://wiki.nexusmods.com/index.php/Getting_started_creating_mods_using_GECK#GECK_Form-ID.2C_Base-ID.2C_Ref-ID.2C_and_Editor-ID GECK Form-ID, Base-ID, Ref-ID, and Editor-ID] section of the wiki [http://wiki.nexusmods.com/index.php/Getting_started_creating_mods_using_GECK Getting started creating mods using GECK] article for a more complete explanation of these terms.  The differences between them are important to understand.

While this has obvious implications for translators, it also means mods developed for a different language version of the game won't work "out of the box" in another language.  The FormIDs won't match.  Conversion would require determining what the FormID in one language version is in the other language version.

=== Issue - SOUND - Music Licenses and Sources ===
 +
Symptoms: Questions regarding the ability to include "music" or "songs" in any form in a mod.
 +
 +
* Cause: Published music (instrumentals, digital, and vocals) is usually by default "copyright protected", which means you need to have purchased a ''license'' to include it in your mods or online videos published for use by others.  This includes music (in whatever form or manner of production) included in other media (such as games, videos, and films) as well as downloaded from various websites.
 +
: The following terms are taken from the [https://buffer.com/library/background-music-video/ Buffer.com Background Music Video] page:
 +
::* Royalty Free
 +
::: Royalty free music gives users the right to use copyrighted music without having to pay “royalties” for recurring use of the content. In other words, royalty free music allows the buyer to ''pay the music license only once'' and use the music for as long as they want.
 +
::: Royalty free often gets mistaken for “free” music, which is not the case in many situations. The author or artist who has composed the music decides what kind of license it will have, and therefore, the costs associated.
 +
 +
::* Public Domain
 +
::: Public domain refers to all works that are not protected by copyright and can be used without permission or without having to pay the original author/artist. Public domain essentially gives free use of the music in whatever manner a user sees fit.
 +
::: Essentially, that means that content within the public domain can be copied, distributed, interpreted, and displayed in public for free as if it belongs to everyone.
 +
 +
::* Creative Commons
 +
::: [https://creativecommons.org/licenses/ Creative Commons] is one of several public copyright licenses that enable the ''free distribution'' of an otherwise ''copyrighted'' work. At the core of the Creative Commons license is the idea that every CC license ensures copyright holders retain control and get the credit for their work they deserve. It’s a standardized way to grant copyright permissions to their creative work.
 +
 +
:* Solution: Obtain music which is in the "public domain" either by explicit placement there in it's licensing terms, or expired copyright (dates vary by jurisdiction and number of authors); or which is explicitly published as "licensed royalty free" but probably still requires an initial purchase.  This can get complicated as "music" consists of separate components such as "instruments", "performance" by particular artists, and "lyrics". "Licenses" usually must be purchased (otherwise how would the author/artists get any form of compensation for their work).  See [https://incompetech.com/wordpress/2020/10/composerish-perils-of-buying-instruments-from-instagram-meditation-music-royalty-free-vs-commercial-music/ Composerish: Perils of buying instruments from Instagram, Meditation Music, Royalty Free vs Commercial Music] for a discussion.

Overview

This a collection of specific common problems and solutions, along with a general checklist of things known to contribute to problems, collected from around the web. The "Fallout NV Mod Conflict Troubleshooting" thread in the "Fallout New Vegas Mod Troubleshooting" forum is for questions, suggestions, and discussion of this article's contents.

The article is organized around various generic topics, with specific mod conflicts or issues that don't fit into the other categories under "Solutions to Miscellaneous problems".

If you haven't already, it is suggested to read the wiki article FNV General Mod Use Advice first to understand basic terminology as used here and differences in FNV from other games you may be used to modding.

Troubleshooting is a logical process of elimination. If all logic fails, you have to revert back to a vanilla game and slowly re-install mods, testing each one thoroughly before adding the next. It is a trade-off of "time" versus "effort". Where that tipping point lies is up to you. This is why you are always advised to follow a slow "install and test each mod one at a time" procedure when first setting up your game. Then you know specifically which mod is causing your problem, which saves time.

The How to ask for help wiki article applies to any game. Read it before posting your next problem in the forums to speed up getting to the correct solution. The time you are wasting otherwise is not just your own.

Checklist

Standard list of things to ask yourself about your current FNV problem:
00. Did you install Steam under the default location of the "C:\Program Files" tree? This causes many "strange" problems not otherwise explainable. As painful as it may sound, read the wiki article Installing Games on Windows Vista+ and move at least FNV. That article has a link to the official Steam Procedure (a good indication that they now recognize the need to correct this). This should be the first solution you try. Otherwise you will spend a lot of time and effort trying other solutions, and still have to move the game files in the end anyway.

Note that the GOG DRM-free version of FNV default install location is "C:\GOG Games\Fallout New Vegas". It does not have this issue, in addition to already being 4GB memory enabled. DO NOT run the 4GB Patcher against the GOG version. This situation has been known to prevent the ability to save any game files. Other unpredictable problems may occur.

01. Are you getting an error message? What is that pointing to as the source of the problem: the game, Steam, or Windows?

02. What most recently changed (as far as what you have deliberately done to your game is concerned: New, updated, or removed mods or plugins)?
02b. Did any of the following which interact with the game get updated or changed recently. They are prime suspects if nothing in the game itself changed:

a. Video driver. (The latest is not always tested against an older game.)
b. Sound driver.
c. Mouse driver. ("Advanced features" are not always compatible with the game.)
d. Power Outage? Run a chkdsk on the drive to fix any errors that might have occurred.
e. Windows system update (consider rolling back to the previous restore point).

03. If you have recently "verified local files" or "re-installed" the game, try renaming both the INI files in the "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV" folder, and let the game rebuild them. (There might have been some unexpected changes.) Rename to anything you choose. I usually just add to the extension: from "<filename>.ini" to "<filename>.ini.old". The purpose is to be able to examine the old files for things you want to be able to replicate in the new versions of the same file.

Before you make any changes to the game INI files, please make backups and put them in a safe place. See the Game INI files section of the "FNV General Mod Use Advice" article for details.You have been warned!
If you make any changes to any of the game INI files, remember to change it in all three files (after you have backups of the originals): the "Fallout_default.ini" in the game root folder (which only gets used to recreate the other two when they are not found), and the two in "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV" folder ("FALLOUT.ini" and "FalloutPrefs.ini"). Otherwise you tend to lose track of which you actually changed if you have to "verify files".
Note that if you are currently or have used "Mod Organizer", MO uses its own copies of "Fallout.ini" and "FalloutPrefs.ini" (from when the MO profile was created), located in the "<Steam install path>\steamapps\common\Fallout New Vegas\Mod Organizer\profiles\<Your Profile Name>" folder. These files need to be changed as well.

04. Does the most recent mod change use New Vegas Script Extender (NVSE) or supplemental plugins like JIP NVSE Plugin or "Lutana NVSE Plugin"? Check that log (in the game's root folder: i.e. "<Steam install path>\steamapps\common\Fallout New Vegas").

According to this post in the JIP NVSE thread, mods are supposed to use and expect the following results when checking which version has been loaded, either in scripts or the game console ("<~>"); even from the Main Menu (without loading a "save game" file).
* GetNVSEVersion: returns integer (e.g. "5")
* GetJIPLNVersion / GetLNVersion: returns loaded JIP LN main version as float (xx.xxxx)
* GetPluginVersion "<string>": (quotes are required)
  • "JIP NVSE Plugin": returns loaded JIP LN main version as float (xx.xxxx)
  • "lutana_nvse": returns loaded JIP LN main version as float (xx.xxxx)
  • IsPluginInstalled:
  • "lutana_nvse" returns 1
If you previously had the "lutana nvse" plugin installed, make sure you have removed all "lutana*.*" files from both the game root and "Data\NVSE\Plugins" folders. Otherwise this can cause the "GetJIPLNVersion" command to fail with the error "command not found".
NVSE and related plugins must be manually installed because most mod managers assume everything in them needs to go into the "Data" folder instead of their respective specific locations. Check their documentation carefully.
When installing New Vegas Script Extender (NVSE), the nvse_loader.exe file should be in the game root folder: i.e. "<Steam install path>\steamapps\common\Fallout New Vegas"), so it's along with the FalloutNV.exe file. However, just unpacking the NVSE archive package to the "Fallout New Vegas" folder may not create a "Data\NVSE" folder or the "Data\NVSE\Plugins" sub-folder upon installation unless you tell it to include sub-folders when doing so. If not, you will have to do so manually. It definitely does not create a configuration file (in the "NVSE" sub-folder), nor automatically enable it's log files (which will be found in the game's root folder). You need to do so yourself, using any plaintext editor such as Windows NotePad. Supplemental NVSE Plugins such as JIP, Lutana, MCM, NVAC, or NVSR should go into the "Data\NVSE\Plugins" folder; along with their configuration/INI files.
  • If not present, manually create folder "NVSE" under the game "Data" folder (at the same level as the "Meshes" and "Textures" folders), and then "Plugins" under the "NVSE" folder.
  • Make sure "hide known file types" is disabled in Windows/File Explorer's "Folder Options" menu, or your new INI file in the next step will have a hidden ".txt" extension which you don't want. (The DigitalCitizen.life article 8 ways to open the Folder Options window, in Windows (all versions) will show you how to access that.)
  • In the folder "Data\NVSE" create a new text file and name it "nvse_config.ini".
  • Copy and paste the following into "nvse_config.ini":
This will enable the game's error log the next time you run it, which will then be found in your FNV root folder (where you put the NVSE executable files). There will be at least three files: "falloutnv_error.log", "falloutnv_havok.log", and "nvse.log". The first one is very useful for finding broken stuff in mods or the cause of crashes. Not everything in it is an error so keep that in mind; some are just warnings. The "nvse.log" is helpful to identify problems with NVSE itself, and plugins that rely upon it.
The warnings are supposed to be written by the game engine in "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV\warnings.txt", but this may be dependent upon the "log level" in the "nvse_config.ini". The default is level "1" and there is no "warnings.txt" file created; but it goes up to level "5" (debugging) with increasing verbosity. However, it appears this "warnings" file feature was never actually implemented for FNV, but have been restored by the GECK Extender Plugin for NVSE.
  • To activate the "Sheson patch", Add the following before the "[Logging]" section of the "nvse_config.ini" file:
Using a size of "240" or "256" is suggested if you are not using FNV4GB or some other means to utilize the maximum ~4GB of game memory. Too small or too large a heap size causes problems. Keep it under "500" (i.e. "496"), and in multiples of 16. Skyrim SKSE users may be aware of a "scrapheapsizeMB=" setting. This is carried over to NVSE, but is not used in the FNV game engine. Remember, nothing is "free memory". Everything you assign to a "heap" is no longer available to the game itself.
See also entirety of the Issue: CTD without warning, "Out of Memory error", or stops responding after the Main Menu" in this guide.
For help interpreting an error log, please see the How to read most Bethesda game error logs wiki article.


05. Did the mod need to be added to Mod Configuration Menu (MCM) / One HUD (oHUD) / User Interface Organizer (UIO)? (Those mods need to see it when they are installed. See the wiki article HUD-UI-Menu issues and re-install them.)
06. Is your version of Windows 32 or 64-bit? (32-bit may require BOOT.INI changes to use more than 2GB of memory. See this 2-4GB game memory limits and solutions article.) FNV is a 32-bit game, so you need the 32-bit versions of any downloadable tools or libraries, like "C++ Runtimes" or "DirectX drivers" installed on your 64-bit system. 32-bit libraries are not interchangeable with 64-bit versions. They install to different locations. There is a reason MS makes both versions available.
07. Are you using a FNV4GB Loader such as 4GB Fallout New Vegas Updated or an LAA flag Patcher like FNV 4GB Patcher? (Increases available memory. But see the previous question about 32/64-bit Windows. It's related.) Did you turn off any "anti-virus" checking software before patching? (They see any attempts to alter programs as "malware".)

How can you tell if the 4GB Patch is working?
The JIP LN NVSE Plugin has a function which can be run from the console: "GetIsLAA" (not case sensitive).
Possible return codes:
  • 0=patch is not applied
  • 1=patch was applied to the executable, but extra memory is not being allocated
  • 2=successfully allocated extra memory from the patch and is fully working.
If "GetIsLAA" is returning code "1", try running the game from a "local administrator" account. If that is succesfull, you need to move the game install location out of the "C:\Program Files" folder tree, or correct the "permissions" on the folder you moved it to, as you are going to have other problems down the road. Please see the wiki "Installing Games on Windows Vista+" article for details.
Alternatively: if the Windows "Task Manager" indicates the "FalloutNV.exe" program has more than 2GB (2,000,000KB) of "Memory (Private Working Set)", then the 4GB Patch is in effect. However, to the contrary: less does not mean it is not working. The game simply hasn't needed that much memory as yet.

08. Are you using an ENB preset? (Alters the graphics environment, including INI changes.) If you aren't sure, then probably not. This is a "third party tool" you would have to manually add. You should wait until you have a stable game before adding a "post-processor" like it to the mix.
09. Are you using Reshade/SweetFX? (Alters the graphics environment, including INI changes.) You should wait until you have a stable game before adding a "post-processor" like it to the mix.
10. Check the game graphic & ENB/SweetFX options do not conflict with video driver settings. (Anti-aliasing, ambient occlusion, anisotropic sample size, v-sync, anything else that is mentioned.) If you didn't install either of these then the question does do not apply.
11. Are you using LOOT to sort your mod "load order" (LO)? (Reduces mod conflicts.) If you don't like LOOT's results, or wish total control over your LO, see the wiki article Load order and you for an approach to organizing the LO and creating a "merge patch" file to manually resolve conflicts.

It's always useful to post your "Load Order" (LO) with your problem description. (Use the "Special BBCode" button in the Forum "Reply" menu bar to put the LO in "Spoiler" tags. See the article How to markup images (etc) in forum posts and comments.) Screenshots are not the best way to convey your LO, because they usually can't include everything in one image and (depending upon where you took the shot) may not show the actual "load order". LOOT can copy your LO into a list suitable for posting on forums. (It's under the ":" with three dots to the extreme right in it's menu bar. Current Tome of xEdit online documentation here.) Most "mod managers" have a similar "LO List" capability. But the total number of mods you have installed in the DATA folder is also important, because even inactive plugins are counted against the so-called "140 cap". LOOT provides both numbers: active and total installed.

12. Do you have more than 130 active plugins in your LO, or more than 140 plugins installed (active or not) in the game DATA folder? The game can have problems with anywhere from roughly 130-140 active, or too many installed, depending upon your system. This may manifest in any number of strange ways to include apparent missing meshes and textures that were there before, along with CTDs.
13. If you are having a "red icon" problem, see the ArchiveInvalidation (by Manager) sub-topic.

  • When in doubt, it will never harm things to try toggling "ArchiveInvalidation" off and then on again.

14. Are you missing any of the "game fixer" mods? See the Issue: Vanilla game bugs sub-topic for a list of specific recommendations.

15. If any LOD files (distant landscape terrain) have been added, re-run TES4LL (from Nexus Oblivion or GitHub). 'TES4LL is used to "fix up" LOD/VWD mesh files, and works along with FNVLODGen. The VWD/LOD Overview page includes a basic batch file for assistance in automating the TES4LL process. Edit in the following parameters in the "tes4ll_make_..." files for FNV:
... _gamemode=FalloutNV _worldspace=WastelandNV _worldspaceid=894758 _worldspaceidhex=000DA726 ...
  • A more recent alternative to TES4LL is xLODGen - Terrain LOD beta for FNV, FO3, FO4, FO4VR, TES5, SSE, TES5VR, ENDERAL by sheson, an updated version of the basic xLODGen tool (of which FNVLODGen is a game specific implementation) which now has the option to generate LOD meshes and textures "exactly" like the CK. Read at least the first post instructions carefully. Specifying an "output file" should be considered mandatory.
See the TESTG site for a glossary of terms and descriptions of/links to these and other utilities.

16. If the LO has changed, re-run FNVLODGen after LOOT. (Rebuilds LOD quadrants (quads), which are "load order" dependent.)
17. Use FNVEdit (loading the entire LO) to check for Masters that are missing or loading after Dependencies. See the wiki tutorial Missing Masters. There is full documentation of FNVEdit (for both FO3 and FNV) in the online docs Tome of xEdit and the downloadable PDF FNVEdit Training Manual.
18. Are you using a Wrye Flash Bashed Patch or a manually created "merge patch" file? (Resolves record level conflicts.) See S.T.E.P. Merging Plugins Guide which covers both approaches, or the video Making a Merge Patch by Roy Batty for the "merge up" approach. (Use of "Mod Organizer" is not required.) Use the Wrye Bash Pictorial Guide to quickly get functional with "Wrye Flash", which I think is the easier approach for a novice modder.
19. If you are using "Wrye Flash" to create a "Bashed Patch", have you gotten all "green" checkboxes for all your mods? See the first post in the pinned thread Fallout New Vegas Beginners guide to modding by gromulos.
20. Was there an update to a mod that has been included in a "merged plugins" or "merge patch" file? Rebuild the "merge" file.
21. Did any system or driver updates occur? (Third party processes might be the cause if nothing else changed.)
22. Does your hardware meet the game's minimum requirements?
23. Have you tried running the game in "windowed mode"? This has been known to unexpectedly fix CTDs and "out of memory" errors on some older hardware. If you prefer the "borderless" version of "windowed mode", install New Vegas Script Extender (NVSE) and use the One Tweak for FNV mod.

Alternatively, there are free third-party tools that run games (not just FNV) in "borderless windowed mode", such as Borderless Gaming.

24. Try turning off any unnecessary background processes, such as "anti-virus" or "anti-malware" programs (unneeded if you are running your game in "offline" mode), multiplayer "overlays" like "OverWolf" (this is single-player after all), the Steam overlay, etc., at least on a temporary basis to see if they are interfering.
25. Finally, the problem might be an overheating hardware component. This usually shows up after a period of time which is typically fairly consistent but unpredictable as to when it manifests. Try installing and keeping an eye on a temperature monitor, such as Speedfan (freeware). Your motherboard manufacturer probably has one available as well. And it never hurts to clean out any dust collecting in the computer case. Be sure to block any fans from rotating when you blow it out, so they don't send any unfiltered power surges through the system.

ArchiveInvalidation by Manager

"ArchiveInvalidation" (AI) is a method by which the game is told to look for "loose files" in preference to those in the vanilla BSA files. This is the reliable method to get a mod's own texture and mesh files utilized, assuming you have properly installed those "assets". This post on manual invalidation explains the problem and history quite well.

Check you have "ArchiveInvalidation" (AI) enabled. You may need to "toggle" it off and then on again.

(For links to tutorials and documentation for the individual mod managers, please see the 'Mod Managers' section of the wiki "FNV General Mod Use Advice" article.)

  • Open your mod manager.
  • Mod Organizer (MO): Select your "Profile". Turn on "Automatic Archive Invalidation" in the "Configure Profiles" dialog. Close the mod manager.
Some have found "AI" more difficult to get working in MO. In these cases the following steps are suggested:
1. In MO Settings 'Workarounds': uncheck 'Force-enable game files'.
2. Get a copy of "Fallout - AI!.bsa" (From FOMM or NMM) and copy it to your "Data" directory. (Basically this is an empty BSA file.)
3. Go to the 'Archives' tab in the right MO window. Make sure MO is managing BSA files. Move the "Fallout - AI!.bsa" to the top of the list.
4. Try "Automatic Archive Invalidation" in the Profile both OFF and ON.
  • Fallout Mod Manager (FOMM): Depending on the version you have, find "Archive Invalidation" either under the tools tab or find the button "Toggle Archive Invalidation".
  • Nexus Mod Manager (NMM) or the newer Fallout Mod Manager - Forked (FOMM-Forked): if there is a "check mark" shown next to "Archive Invalidation", remove it and close the mod manager. Open the mod manager, open the "Tools" and place a "check mark" next to "Archive Invalidation".
    If there is not a "check mark" next to "Archive Invalidation", place one there and close the mod manager.
  • Vortex: the new "official" Nexus mod manager handles "Archive Invalidation" with an extension called "Gambryo Archive Invalidation". It's enabled when Vortex is installed, and it works automatically for certain Bethesda games.
It now has a dedicated button on the Vortex dashboard.
Per the author Tannin here:
Note that Vortex is now in "Production Release" state, meaning it is "stable", "feature complete", and "bug free" for the majority of users, but bugs may still be found and dealt with. See the Nexus news article for details. Please report problems to the Vortex Forum.
  • Wrye Flash (WF): click on the "Installers" tab, then right-click on the "Package" column header (gray bar) and click to place a "check mark" on the "BSA Redirection" context menu entry. Then right-click on the "Package" column header again and select "Anneal All".
  • If you don't use a "mod manager", you should. But there are mods out there that provide the same "BSA Redirection" functionality (the currently more effective form of "ArchiveInvalidation") as an addon.
  • If a mod manager's AI doesn't seem to be working, check the INI files under "[Archive]" for the "bInvalidateOlderFiles=" setting. Try switching the value between "=0" and "=1". (Some seem to need it one way, and others the opposite.) See also the wiki article Archive invalidation for details on where the "fake bsa" file needs to go in the "sArchiveList=" line.
  • Note that various mod managers can implement "BSA Redirection" in the same way, but be using different BSA filenames. This filename gets inserted in the INI files (under the "[Archive]" section in the "sArchiveList=" setting string of files) using variation names such as "Fallout - AI!.bsa", "Fallout - ArchiveInvalidation.bsa", etc. If you switch mod managers, make sure your INI files are using the correct filename as that manager is expecting. In general this file is placed first or second in the "sArchiveList=" list.
If you are using the JIP LN NVSE Plugin optional "FalloutCustom.ini" file to override the standard INI file settings, make sure it has been changed as well.

Mod Conflict Isolation

If you have to isolate a mod conflict, try first "disabling" half your mods, and testing. If the problem disappears, then you know the mod conflict lies in the "disabled" half of the mods. Re-enable half of the "disabled" half of the mods (i.e. now down to 1/4 of the total) while disabling the entirety of the other (previously enabled) half, and test. Keep repeating this "halving the remainder" process until you have narrowed it down to the mod that causes the problem only when it is active. This is the quickest way to isolate a problem mod.

Whenever you "disable/deactivate/uninstall" a mod, make a "clean save" file before testing the result. For FNV a "clean save" from an existing game save seems to be just a "full save" file (not a "quick save") that has been loaded, displayed the "missing content" message for the disabled plugin(s), and you continued on into the game; and then waiting about 10 seconds for scripts to initialize before saving again. This is a minimal clean save procedure. (If you appear to still have "residue" remaining after trying this procedure, try the more complete process laid out in the Tes4Mod:Clean_Save procedure for Oblivion.) However, it is usually preferable to test using a "new" game "full save" file from just after you create a "new" character with a different name. This avoids the possible issue of any corruption or problems "burned into" the save file.

Please see also the 'Fourth Rule: Reloading "save game" files' section of the wiki FNV General Mod Use Advice article.

If disabling mods does not pin down the culprit, then you have to uninstall them to completely remove their influence, because they overwrote something which is causing the problem. You can use the same "halving" technique but often it will be quicker to just uninstall everything and start over from a "vanilla" game that you have tested has no problems.

If you uninstalled and re-installed the game but even without mods it crashes on startup, likely you forgot to clear out your "C:\Users\<YourAccountName>\Documents\My Games\FalloutNV" folder. The game places your specific versions of the Fallout and FalloutPrefs INI files there, along with your "save games". Try renaming the "Users" folder INI files first. I usually just add to the extension: from "<filename>.ini" to "<filename>.ini.old", but it can be anything. The purpose is to be able to examine the old files for things you want to be able to replicate in the new versions of the same file. Then if that fails: move the "saves" elsewhere, delete that FalloutNV folder's content, and re-install again. If you have to re-install again anyway, be sure to install to a folder that is not under the default "C:\Program Files" folder tree. See Installing Games on Windows Vista+ for the rationale and guidance. (Actually, you should move your game from the default location regardless, but I realize this is unwelcome advice to most people. It is still the single best "fix" you can do for yourself. Read that article.)

When the above is not sufficient to resolve your problem, please report what steps you have tried so we don't waste time suggesting you repeat something. In such cases, report the actual steps: not just "I followed the guide". We need to know you didn't miss or misinterpret something.

It's always useful to post your Load Order (in "Spoiler" tags. Use the "Special BBCode" button in the Forum "Reply" menu bar, just to the left of the "Fonts" pick-list). Screenshots are not the best way to convey your LO, because they usually can't include everything in one image and make it difficult to determine if you have too many plugins. LOOT can copy your LO into a list suitable for posting on forums. (It's under the ":" with three dots to the extreme right in it's menu bar.) Most "mod managers" have a similar "LO List" capability. But the total number of mods you have installed in the DATA folder is also important, because even inactive plugins are counted against the so-called "140 cap".

Towards Game Stability

  • The videographer GamePoets has recently (30 Oct 2018) released a definitive 12:11 minute Performance & Stability Guide YouTube video for "Tale of Two Wastelands (TTW)" covering many of the suggestions in this article. However, while it does not conflict with any advice here and works just as well for FNV, it also does not cover quite as many options. It does make an excellent and recommended starting point for initially dealing with such issues.
  • If you want a stable game, don't make any changes to your setup once you start playing and making "save game" files. Even updates to current mods run the risk of making things unstable after the point they are added. If you do update, ensure you know which save to revert to prior to that update if it goes wrong, and test it thoroughly immediately.
  • Removing a mod that has stored some elements in a "save file" will leave residue (even with a "clean save") that can cause problems down the road. In particular you have to watch out for mods that use scripts to permanently change form and leveled lists (such as, purely as an example, the popular Millenia's Weapon mods). This is not, in and of itself, a bad thing as there are compatibility advantages to using this "script" technique. Such mods usually point this out in their description. But it is something to pay attention to when experimenting. It's better to find out what causes problems before you start to play in earnest. The general rule is: NEVER remove a mod from your load order once you have it in a "save game" file unless you are prepared to start over at some (possibly considerably) later point.

Solutions to Starting the game problems

Issue - After moving game from the default install location FNV4GB fails to launch

The FNV4GB.log looks similar to the following when trying to launch it:

The "Executable name" (3rd line) points to the correct location. The registry key "HKLM\SOFTWARE\Valve\Steam" value "InstallPath" (9th line; value content shown in 11th line) does not.
  • Cause: The registry has not been properly updated.
  • Solution: Running the vanilla EXE launcher (from the Steam Client or 'FalloutNVLauncher.exe') first after moving (at least once) updates the registry addresses. After that FNV4GB will work correctly.

Issue - Application load Windows errors

  • Cause-1: Specifically error codes: "P:0000065432" or "5:0000065434" indicatea problem with the Steam Client.
The "P:" prefix seems to show up when the Steam Client is not running.
The "5:" prefix appears to occur when starting the game from it's EXE (such as the Launcher or the "FalloutNV.EXE"), but then it fails to locate the Steam Client executable on local disk even though it is already running and loaded into memory. Which seems to be confirmed as it disappears when the SteamClient.exe (and only that one file) is placed in the game root folder.
Both instances produce the same "error code" message with only the prefix different.
  • Solution-1a: The Steam Client may be in "Offline" mode and minimized to the system tray, but must remain running while launching the game, even with "nvse_launcher" or "fnv4gb".
Note that the Steam Client is what displays the "Library", "Store", etc. It is a separate piece of software from "the game" and performs the authentication that your copy of the game is legitimate.
  • Solution-1b: Sometimes all that is needed is to open the "Task Manager" (<Ctrl+Alt+Del> or right-click on the "Task Bar" | "Start Task Manager"), switch to the "Processes" tab, and right-click the "image name" Steam.exe task and select "End Process Tree". Then restart the game again.
  • Solution-1c: When this occurs with the "FalloutNVLauncher.exe" file (whether or not after installing NVSE), some people have found that COPYing the Steam.EXE file (usually located in the "<install path>\Steam\" folder), into the game root folder (i.e. along with the game and NVSE EXE files in "<install path>\SteamLibrary\steamapps\common\Fallout New Vegas"), resolves the problem.  This copy of Steam.EXE may need to be updated as well after the Steam Client has updated.
  • Cause-2: For some people, the game will not run without "Multi-threaded AI" enabled.
  • Solution-2: In all three INI files, under the "[General]" section set the following values:
bUseThreadedAI=1


 

and add the line:
iNumHWThreads=


and set that to however many cores your processor has. Note this added line is not a "performance" tweak (the game does multi-threading by default and the "iNumHWThreads=" setting may restrict it) and is not recommended for everyone in general. Some people have experienced adverse effects. Use with caution and test the result. When in doubt, start with "2".

  • Cause-3: Error message "Application was unable to start correctly", and Windows "Event Viewer" Application Error: "Exception code: 0xc0000005".
Generally this error code means the program is trying to access protected memory or outside of the space allocated to it. It's one of the most common OS errors seen. In this case the game is failing to start as a result.
  • Solution-3a: The Nov 2016 Win10 updates should fix any WDDK based issues with video drivers or previous updates. Try applying system updates first.
  • Solution-3b: See the article Exception Error Code 0xc0000005 Fixed on Windows 7 & 10.
  • Solution-3c: See the article How to fix error code 0xc0000005 under "application was unable to start correctly" for other things to do to fix it.
  • Solution-3d: The mod New Vegas Tick Fix (NVTF) was developed to correct specific problems encountered with Windows 10 as an alternative to the older "New Vegas Stutter Remover (NVSR)". Among it's NVTF.INI file settings is the entry "bInlineCommonFunctions=". Some have reported that disabling this entry ("=0") corrects this specific error, particularly if it occurs after the game has started.
  • Cause-4: Error message "The application was unable to start correctly (0xc000007b)" has several possible causes. The TomsHardWare site has a good list of these. But when the problem only occurs with FNV on a Windows 10 or later system, the most likely reason is due to the age of the game. At the time it was released, the game was designed to look for DirectX9 files with specific versions in the file names. Later versions of DirectX might be "backwards compatible", but the file names are not the same and the game does not recognize them as being equivalent.
  • Cause-5: Generally this only applies if you are unable to get the game to start at all, ever. If it had been running but suddenly starts failing for no apparent reason, most likely it is due to something on the OS side that recently changed: a Windows Update, or a new video/ mouse/ sound/ keyboard driver. See also: Issue: CTD after 10-20 minutes of play (post-Win10 2017 FCU).
It is common advice to update video drivers, but manufacturers often stop testing for older game compatibility. Experience suggests you only update drivers when necessary to resolve a specific problem, and be prepared to "rollback" to an older driver version. Keep at least one version that is known to work "in reserve".
  • Solution-5a: If running the game in online mode through Steam, Set/Change Steam Compatibliity:
  1. Run the Steam Client and login online.
  2. Right-click on the Steam Icon, choose Properties, and if it is on, turn Compatibility off.
  3. Close out Steam Client entirely.
  4. Open Steam again it and attempt to load the game.
  • Solution-5b: If running the game in offline mode by launching from your computer desktop, or if setting "Steam Compatibliity" is not sufficient, Set/Change Windows Compatibility:
  • Note that the Windows 10 "Fall Creator's Update" (FCU, v1709; aka "RedStone 3") reportedly no longer requires this compatibility setting.
  1. Right-click on the Fallout: New Vegas launcher application (FalloutNVLauncher.exe) in the game root folder. (This is C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas (by default), but that location is not recommended. Please see the wiki Installing Games on Windows Vista+ article for why not and help on moving it.)
  2. Select Troubleshoot Compatibility.
  3. Choose the Troubleshoot Compatibility option.
  4. Check the box that says The Program requires additional permissions.
  5. Select Yes for the next window and then Test the Program.
  6. Choose Save these settings.
  7. Try to launch the game from your desktop again.

Issue - Black Screen on startup

  • Cause-1: Usually if the game "freezes" but doesn't CTD during the loading screens, it's due to a missing or incorrectly referenced "master file". Usually this is a file with an ESM extension, but less commonly might be one with an ESP extension. (It is a "flag" internally in the file header that makes a file a "master"; not the extension.)
A "missing master" problem can result just from a plugin being in the wrong sequence in the "load order".
  • Solution-1: Use FNVEdit (loading the entire LO) to check for Masters that are missing or loading after Dependencies. See the wiki article Missing Masters for more detailed instructions.
In general, make sure all your ESM files are loaded first with the game ESM (FalloutNV.ESM) as the very first file and those of the DLC next in the order they were released:
  • FalloutNV.ESM
  • DeadMoney
  • HonestHearts
  • OldWorldBlues
  • LonesomeRoad
  • GunRunnersArsenal
    and then the "pre-order packs":
  • ClassicPack
  • MercenaryPack
  • TribalPack
  • CaravanPack
Mod EMS files should follow.
Use LOOT to get a basic sorted mod order. Note that some mods have ESMs that use the ESP extension, so if LOOT sorts them into the ESM group, leave them as it is determining that from the file headers and they really are flagged as ESMs.
  • Cause-2: A Black screen but you can hear sounds and the game seems to be running usually means you have too many plugins active. You can start to have problems anywhere with between 130-140 active plugins depending upon your system. Here "plugins" refers to both ESM and ESP files that are active in your "load order", or present in the game "Data" folder even if not active.
  • Solution-2: Try temporarily disabling enough plugins to get under the cap and see if that gets your screen back. If so, then you need to look into permanently reducing the active plugin count by means of a "bashed" or "merged" patch file, and "merged plugin" files. See the wiki article Merged Plugin Guidelines for Personal Use where the subject is discussed.
  • Cause-3: A Black screen but you can hear sounds and the game seems to be running could mean you have corrupted a HUD-UI-Menu XML file, or have installed a mod that overwrites one. This can usually be confirmed by loading the game without any active mods or "save game" (i.e start a new game). If the screen remains black, you have an XML file issue.
  • Cause-4: A Black screen with CTD (or hang) during the loading screens is usually an indication of a mod conflict or a dependent plugin (i.e. an ESP) loaded before a master plugin (i.e. ESM for the same mod). See the wiki article Missing Masters for more detailed instructions to check for these problems.
  • Solution-4a: Check the date/timestamp on the files in question. Even LOOT can occasionally set the times too close to each other when sorting. They need to have at least a full minute difference to not be considered "the same time" by the game. The ESP must have a later time than it's related ESM. You can use a "file properties" tool like Attribute Changer (freeware) to manually adjust any or all three timestamps (created, modified, accessed) on the files, or try manually moving files around in your mod manager. Note that no two files should have the same "modified" date/timestamp in your "load order" or other problems will arise.
  • Solution-4c: Installing HUD-UI-Menu mods in the wrong order can cause corruption of an XML file in a form of "mod conflict". Please see the wiki "HUD-UI-Menu issues" article.
  • Cause-5: A Black screen during the game loading screen with the rotating roulette wheel, and no sound might be a problem with the audio driver.
  • Solution-5: Locate the sound card or integrated audio device driver for your version of Windows on the vendor site and re-install. (These are often different from those available from "Microsoft Updates".)

Issue - Game freezing on launch after re-install

Thanks to Kitty Black (Purr4me) for the basis of the following in a reply to the Nexus Fallout New Vegas Technical Support thread "Game freezing at launch - I'm stumped":

Upon launching the game after re-installing, it freezes upon getting to the Main Menu screen (where you choose to either "start a new game" or "continue to play").

  • Cause: When you "change" the game executable to be "4GB/LAA aware", you are using an external program.
That external program is NOT part of the game's structure.
The registry values of the external program are hidden from the Steam and GOG game systems.
The registry retains the updated information BY that "third party" program (e.g. 4GB Patcher, NTCore, etc.); not by the game publisher entry.
Windows uses a "Prefetch", a hyperlink to that executable namesake. ("Prefetch" is an algorithm introduced in WinXP that helps anticipate cache misses (times when Windows requests data that isn’t stored in the disk cache), and stores that data on the hard disk for easy retrieval. See What is windows prefetch in windows 10? super-simplified for a basic explanation, or What is Windows Prefetch and Superfetch? for more details and tuning.)
Software cleaners, & uninstaller programs will not touch "Prefetch" files. (They saved in the "C:\Windows\Prefetch" folder with a ".PF" extension if you want to try deleting them.)
The "Prefetch" files do not belong to the games software nor installers programing.
Windows uses those hyperlinks on launch OR verifying valid updates to the executable.
The 4GB/LAA enabler is not part of the game so it's changes will override Steam and GOG systems "validation certificate", making them "invalid".
To bypass the system you need to update the certificate that is downloaded and currently being blocked from installing.
The Steam verifier will show at least 1 invalid or 1 file is in error. (That's the executable it downloaded.)
  • Solution-1: Do not tamper with the properties of the executable unless you know what you are doing.
  • If you just installed the game and the "Steam Client" Interface is running in "online mode", you will get access to the systems utility for certification. If a program refused to run, the utilities will be there in the file's properties menu to install certificates. Otherwise leave the software alone.
  • <Right-click> on the game executable file (FalloutNV.EXE), and bring up it's properties. Follow the instructions given.
  • If the "Steam Client" Interface is NOT running in "online mode" and the game is operational, you will NOT be given access to these utilities.
  • Solution-2: Delete the existing "Pre-fetch" files.
  • Run the "Steam Client" in "online mode".
  • Open the "Library" tab, and select "Properties | Local Files | Verify Integrity of Game Cache".
  • Once the files have been "verified" and updated, run the "FalloutLauncher.exe" BEFORE you patch the game for 4GB.
  • Solution-3: Corrupted Steam "ClientRegistry.blob" file.
  • Use the Windows "Task Manager". End all the Steam related tasks starting from “Steam Client Bootstrapper”.
  • Navigate to the location of your "Steam" folder (default is "C:\Program Files (x86)\Steam").
  • Locate and rename the "ClientRegistry.blob" file to another name such as "ClientRegistry.blob.old".
  • When you next restart Steam this file will be recreated.
  • If that still doesn't resolve the problem, return to that same directory, locate and run "Steamerrorreporter.exe", and relaunch Steam again.
  • Solution-4: Make a backup copy elsewhere first, and then delete the "Steam\AppCache" folder contents. It will be recreated when Steam next launches.
  • Solution-5: Ensure your "Time Zone" is set correctly. This can affect Steam's attempts to collect "real time" data.
  • Open the Windows "Control Panel | Date and time".
  • From the three tabs, choose “Internet Time” and click on “Change Settings”.
  • Check the dialogue box which says “Synchronize with Internet time server”. Click on "Update now". Click on "OK" after the time is updated successfully, and restart Steam.
  • Solution-6: Opening Steam in "Big Picture Mode" (Win10).
  • Right–click on the “Steam.exe” icon on the desktop.
Note: If you don’t have a "Steam" shortcut on the desktop, you can find the “Steam.exe” in the installation directory.
  • Select the “Pin to Taskbar” option from the "context menu" list.
  • <Right–click> on the “Steam” icon in the taskbar and select “Open in Big Picture Mode“.
  • Sign in to your account and press <Alt+Enter> to access Steam in Big Picture mode.
  • Open the Game and check to see if the issue persists.
  • Solution-7: Unplug any JoyStick. (The presence of one sometimes prevents a game from starting until it has been properly configured.)

Issue - GOG DRM-free non-Steam version of FNV compatibility

On 01 Jun 2017, GOG.COM, the on-line game store that licenses DRM-free versions of games released their versions of "Oblivion", "Fallout 3", and "Fallout New Vegas". As "DRM-free", they do not communicate with Steam. They have been modified to work with the GOG Galaxy client, which is similar to Steam's Client for an online community.

Thanks to vulchor and pixelhate on the Nexus "New Vegas Technical Support" forum for quickly assisting with the following information:

  • By default, GOG installs the game to "C:\GOG Games\Fallout New Vegas". This avoids the problems with Steam's default location under the "C:\Program Files" tree.
  • GOG provides a customized set of INI files. Be sure to backup the "Fallout_default.ini" file before making any changes as a precaution.
  • Includes new line "STestFile2=FalloutNV_lang.esp". This file's function has not been determined, but removing the file itself does not prevent the game from running. It's removal may be related to the warning about content no longer being present, listed below.
  • 4GB patching attempts don't work, but this is because that feature is already incorporated into the GOG versions of the games (and GECK). Patching is not required. They already will use up to 4GB of memory for the game. (NOTE: The latest versions of the "4GB Patcher" program are fully compatible and do not break the GOG version any more
