%CompileNoLight
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:This parameter is also available in Source 2013.
Useful for LightmappedGeneric where you need to use some parameters that UnlitGeneric lacks.
Syntax
%compileNoLight 1
Tip:In 's VertexLitGeneric, a similar effect can be applied on models by assigning
vgui/white
to $lightmap
.
