When this parameter is added to materials, it will tell VRAD to not compile a Lightmap page for that material, which saves compile time. Valve introduced this parameter with Alien Swarm, using it with tools/toolsnolight.vmt, the black areas you see in the levels.

Note.pngNote:This parameter is also available in Source 2013.


Useful if you need features from shaders such as LightmappedGeneric or LightmappedReflective which are not present in UnlitGeneric.

Syntax

   %compileNoLight                         1
Tip.pngTip:In Source 2013 Multiplayer's VertexLitGeneric, a similar effect can be applied on models by assigning vgui/white to $lightmap.
