Category: mental ray > Texture
This shader casts a reflection ray of a given color and merges the result with an input color. This can be used to add a reflection effect to a base shader that provides illumination, possibly in conjunction with refractions or transparency added by other base shaders.
If no reflection ray can be cast (because the trace depth has been exceeded, or the reflection ray caused a shader to be called that failed, or the notrace parameter is set), the environment is sampled, if one exists.
