This page gives information about the Self Illumination Render Element.
The Self Illumination Render Element stores the illumination of any self-illuminated materials in the scene. It 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 shows the results of the self-illumination.
This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max and displays its parameters in a rollout at the bottom of the window:
VRayVFB – When enabled, the render element appears in the V-Ray frame buffer.
Deep output – Specifies whether to include this render element in deep images.
Color mapping – Applies the color mapping options specified in the Color mapping rollout (Render Setup window > V-Ray tab) to this render element. This option is enabled by default.
Multiplier – Sets the overall intensity of the render element, where 1.0 is the standard multiplier.
Denoise – Specifies whether to denoise this render element.
The Self Illumination Render Element is useful for changing the appearance of self-illuminated surfaces, after rendering, in a compositing or image editing software. See the render before and after compositing.
The VRaySelfIllumination Render Element is Added to the Beauty render to form the final image.
- This element contains only the light geometry itself, not the light emitted from it. Lighting information is contained in the Lighting Render Elements.
