Raw GI

The Raw Global Illumination Render Channel stores how much indirect lighting (reflected diffuse light) is received by surfaces in the scene. This raw channel is useful for fine-tuning indirect lighting in the compositing process.

The Raw GI Render channel is untouched by the diffuse colors of the scene and represents the pure indirect lighting contribution. You can use this raw channel to reconstitute the GI Render Channel by multiplying the Raw GI with the  Diffuse.

This raw render channel must be rendered along with the Global Illumination channel (GI) for proper results.
