How to install Fallout 76 BA2 archive mods
Create the following file: <Documents Folder>\My Games\Fallout 76\Fallout76Custom.in This can be done by either creating a text file and renaming the extension to .ini (requires File Name Extensions to be enabled), or by copying another .ini file, renaming it, and delting the contents.
Copy and paste the following two lines into Fallout76Custom.ini:
[Archive] SResourceArchiveList2 =
Entries are separated by a comma. Whenever you want to add a mod's archive to your load list, simply append the archive name, including the .ba2 extension, to the end of this list. To stop loading the archive, remove it from the list.
The descriptions of some mods are out of date and will tell you to copy these lines to the Fallout76Custom.ini.
[Archive] SResourceArchiveList2 = SeventySix - Animations.ba2, SeventySix - EnlightenInteriors.ba2, SeventySix - GeneratedTextures.ba2, SeventySix - EnlightenExteriors01.ba2, SeventySix - EnlightenExteriors02.ba2
This is no longer necessary after game updates, and it's best to not include them.
A few mods use a different archive list and will have a different archive list in their description, such as
[Archive] sResourceIndexFileList = SeventySix - Textures01.ba2, SeventySix - Textures02.ba2, SeventySix - Textures03.ba2, SeventySix - Textures04.ba2, SeventySix - Textures05.ba2, SeventySix - Textures06.ba2
Again, listing the SeventySix archives is an out of date method. In this case, simply add "sResourceIndexFileList =" to a new line under "sResourceArchiveList2 = " like so
[Archive] sResourceArchiveList2 = sResourceIndexFileList =
Then append the mod's archive to the list the mod uses.
