Shaders in Glass

The Glass folder of hl2_misc_dir.vpk and hl2_textures_dir.vpk contain shaders dedicated to windows and glass materials:

• LightmappedGeneric is used for 46 materials.
• LightmappedGeneric_DX6 is used for the glasswindowbreak070a.vmt material (as a fallback shader for the LightmappedGeneric shader).

Dedicated Shaders

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

LightmappedTwoTexture

• Two textures are mixed evenly and multiplied by a lightmap. Useful if one or both base textures are in motion.
• Used in only one material: glasswindow018a_cracked.vmt
• Can be found in Source SDK 2013 MP source code.

ShatteredGlass

• Used in only one material: glasswindowbreak070b.vmt
• Only referred to once in released mod code (in src\utils\vbsp\cubemap.cpp).
• Closely related to the $crackmaterial parameter, which in turn is related to the func_breakable_surf entity.

ShatteredGlass_DX7

• Used in the glasswindowbreak070b.vmt material (as a fallback shader for the ShatteredGlass shader). See above.

ShatteredGlass_DX8

• Used in the glasswindowbreak070b.vmt material (as a fallback shader for the ShatteredGlass shader). See above.
