View Full Version : MR SSS Shader

07 July 2009, 08:05 AM

I've run into this problem many times and just avoided it. Using the SSS Shader with Mental Ray Photographic exposure renders out any object completly black. Why is this? I'm using MAX2009. Is there something that I am missing?

Appreciate your help. Cheers

I'm guessing you still have the exposure value set to 15?
When you dial it down to say, a value of 1 your SSS shader should be visible again.

Its an indoor scene, exposure set to 12. Room looks fine, but as I said the objects with SSS are just rendered completely black. Setting it to 1 blows out the room. I did notice it starts showing up at very low exposure levels but that's not helpful. Any other ideas???

If I remember correctly, you should uncheck the "screen (soft) compositing of layers" option in the materials advanced options rollout when using mr photographic exposure control.
