Tip:This shader 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.
Note:Does not accept any translucency parameters, including $alpha, $alphatest, $additive and $translucent.

Modulate is a Pixel shader available in all 
Source games. It modulates the colors of any pixels behind it.
Tip:This shader 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.Description
Accepts only the following parameters:
Note:Does not accept any translucency parameters, including $alpha, $alphatest, $additive and $translucent.
