Modulate is a shader that modulates the colors of any pixels behind 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.

Tip:This can be effectively used to fake various features that Source may not support, such as vertex coloring or lightmapping on models, by creating a surface above the first one to modulate it.

Warning:Expensive if multiple are used together.
