The Raw Global Illumination Render Element stores how much indirect lighting (reflected diffuse light) is received by surfaces in the scene. This raw element is useful for fine-tuning indirect lighting in the compositing process.
The vrayRE_Raw_GI pass is untouched by the diffuse colors of the scene and represents the pure indirect lighting contribution. You can use this raw element to reconstitute the vrayRE_GI by multiplying the vrayRE_Raw_GI with the vrayRE_Diffuse .
