I have a room with a yellow-orange tile floor. The lights have the indirect lighting saturation set to 0, but the room is still getting a strong orange glow. How do I kill the indirect lighting color tinting?
You can adjust the diffuse boost on the material
The diffuse boost wasn’t the problem. It seems the indirect lighting saturation setting is broken or ignored by lightmass. The fix is to use the GIReplace node inside the material.
