Values

Name	Description
TLM_VolumetricNonDirectional	Lighting will be calculated for a volume, without directionality.
TLM_VolumetricDirectional	Lighting will be calculated for a volume, with directionality so that the normal of the material is taken into account.
TLM_VolumetricPerVertexNonDirectional	Same as Volumetric Non Directional, but lighting is only evaluated at vertices so the pixel shader cost is significantly less.
TLM_VolumetricPerVertexDirectional	Same as Volumetric Directional, but lighting is only evaluated at vertices so the pixel shader cost is significantly less.
TLM_Surface	Lighting will be calculated for a surface.
TLM_SurfacePerPixelLighting	Lighting will be calculated for a surface.
TLM_MAX
