Illum Shader
Overview
The Illum Shader is the most commonly used shader. It can be used to create an extremely wide variety of effects. If there is no specific shader for the type of effect you are trying to achieve, use the Illum Shader.
Shader Params
Param | Description | Shader Gen Option |
|---|---|---|
Emittance Map Gamma | Expands lower range of emittance texture and allows darker colors to be interpreted as even less bright. This can be necessary to make a strongly emissive surface/object like a flame appear smooth. (1.0: Original range, 2.0: Maximum range) | Default |

Shader Gen Params
Param | Description |
|---|---|
Detail mapping | See Unified Detail Mapping for more information. |
Offset bump mapping | See Displacement Maps for more information. |
Vertex Colors | Allows the use of fake ambient occlusion by using vertex colors, or adds a bit more depth and contrast to the 3D model. |
Decal | Activate this function if you use a Decal. Decal planes are normally placed very close to other geometry. |
