This page provides information on the Self Illumination Render Element.


Page Contents



The Self Illumination Render Element isolates self-illuminated materials, including V-Ray Mesh Lights, objects with the VRayLightMtl, and any objects with Self-Illumination enabled in their V-Ray material.

This render element is useful for brightening or color-correcting self-illuminated materials in the final composite.

For example, the material VRayMtl has a parameter for self-illumination. If this parameter is set to a non-black color value, this render element will show the results of the self-illumination.
