The Global Illumination Render Elements store indirect lighting information calculated in the scene.

 Global Illumination is the indirect lighting bouncing around within a scene to contribute to the overall illumination, as opposed to direct lighting from a light source. The following passes may be generated:


The Global Illumination render element itself (VRayGlobalIllumination) can be used in Back to Beauty compositing to add in the GI lighting contribution to the scene. The GI contribution may be adjusted (tinted, brightened, darkened, etc.) in the composite as needed without the need to rerender the scene. 

When even more control over the GI contribution to the final image is desired, this main Global Illumination Render Element can be re-created by multiplying the VRayRawGlobalIllumination Render Element with the Diffuse Filter Render Element:

VRayRawGlobalIllumination x VrayDiffuseFilter = VRayGlobalIllumination
