Dedicated Shaders

The following shaders are more or less exclusively used for this folder:

• It is also, to a much lesser extent, used in the Effects\ and Sprites\ folders.

DecalModulate

• Used in 55 materials in these folders only.
• See Using Modulation on how to use this.
• Only referred to once (in src\utils\xwad\xwad.cpp) in the released mod code.

DecalBaseTimesLightmapAlphaBlendSelfIllum

• Used in the materials decalglasswindow003a.vmt, decalmetalvent004a.vmt and decalporthole001b.vmt in these folders only.
• Replaced by LightmappedGeneric in numerous materials in both this folder and the Props\ folder.
• Not found in released mod code.

ShadowModel

• Used in only one material: rendermodelshadow.vmt
• Probably referred once (in src\cl_dll\clientshadowmgr.cpp) in the released mod code.
