This page provides information about the Self-Illumination render channel in V-Ray for Blender. Overview The Self-Illumination Render Channel stores the illumination of any self-illuminated materials in the scene. It isolates self-illuminated materials, including  V-Ray Mesh Lights , objects with the  V-Ray Light Material , and any objects with Self-Illumination enabled in their  V-Ray Material . This render channel is useful for brightening or color-correcting self-illuminated materials in the final composite. For example, the  V-Ray Material  has a parameter for self-illumination. If this parameter is set to a non-black color value, this render channel will show the results of the self-illumination.
