If you adjust the output of a map within max using the curves provided, and you take part of the map below 0, does that mean that the material will “absorb” GI?
I have a diffuse map that’s easier to adjust in Max than in PS to get what I want, and I’m curious about how this affects the GI solutions with VRay. I know that if I take the map’s output above 1, that the map will generate light in the scene (because it bounces more than it receives). Is the inverse true?
Nope, it clamps at 0.0, however much you push it.
I tried -1000.0 as rgb multiplier, and 0.0 and there is no difference whatsoever in speed or final image results

That’s great to know. Thanks!
I can see the need for having and adsorbing material, but I was just afraid what I was doing would be unintentionally doing that.
Negative lights are the only things that can do that really. Black materials kill light but can’t actively suck it out of a scene in the way you describe.
