$allowdiffusemodulation

$allowdiffusemodulation is a material shader parameter available in all Source games since Left 4 Dead for VertexLitGeneric. It prevents a material from being tinted by either $color2 or the rendercolor parameter. This is useful for situations where you have a model made up of multiple materials, some which you might want tint-able and some not.

 Note: This parameter exists as $notint in Counter-Strike: Global Offensive and Portal 2: Community Edition.
