Here are the various methods regarding the addition or removal of glowmaps:
Method #1 - NifSkope materials setting
- NOTE: The glow would affect any NiTriStrip object that shares the same material
- NOTE: The amount of glow applied would be even throughout the entire surface
- NOTE: There can only be a single color for the glow
- NOTE: This method is usually effective if the model was modular and designed with a glow effect in mind.
- Edit the NIF using NifSkope and modify the values under the NiMaterialProperty.
- Set the Emissive color to the desired color and intensity.
Method #2 - Add a glowmap file
- NOTE: The requires the addition of a new file that matches the name of the diffuse texture but with an _g at the end of the name. Example: cuirass_g.dds
- NOTE: The color and amount of the glow can be controlled at the pixel level based on color and brightness.
- Edit the NIF inside NifSkope and modify the values under the NiMaterialProperty. Set the Emissive color from Black to White.
- Create an _g texture file with black areas that should not glow and white / bright areas for areas with maximum intensity for glow and anything in-between. You can use colors as well.
Method #3 - Combination of method #1 and #2
- NOTE: If the glowmap is configured the way you want it but the intensity is off, simply edit the brightness of the Emissive color for quick adjustments.
Method #4 - Removal of glowmaps
To remove a glowmap, you simply reverse the process.
- Delete the _g.dds file.
- Edit the NIF inside NifSkope and change the material properties. Set the Emissive color to Black.
