LightmappedGeneric is a Pixel shader available in all 
Source games. It is the shader most commonly used to render lightmapped brushes and displacements.
Models cannot use this shader; lightmapped models use the VertexLitGeneric shader.

Mapbase
LightmappedGeneric materials in Mapbase should have the shader SDK_LightmappedGeneric.
