Modulate is a shader that modulates the colors of any pixels behind it. This can be effectively used to fake various features that Source may not support, such as vertex coloring or lightmapping on models (already possible for prop_static in 
), by creating a surface above the first one to modulate it.
Description
Accepts only a $basetexture and this texture will be used to modulate pixels. Multiplies the color behind it with this surface's texture.
For a usage tutorial on how to fake vertex coloring or lightmapping, see this post here (halfway through the thread).
Todo: Test performance more. Probably expensive when many layers are in use.
