The Self Illumination Render Element stores the illumination of any self-illuminated materials in the scene.


Overview


The Self Illumination Render Element isolates self-illuminated materials, including V-Ray Mesh Lights, objects with the V-Ray BRDFLight, 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 V-Ray Material has a parameter for self-illumination. If this parameter is set to a non-black color value, this render element shows the results of the self-illumination.


Attributes


The parameters for this render element appear in the V-Ray RenderChannelColor render channels node.

VFB Color Corrections – Applies the post render color adjustments made from the VFB.



Common uses


The Self Illumination Render Element is useful for changing the appearance of self-illuminated surfaces after rendering in compositing or image editing software. See below the render before and after compositing.

Notes


  • This element contains only the light geometry itself, not the light emitted from it. Lighting information is contained in the Lighting Render Elements.
