Renderlayers / contribution maps
Hi! I just watched the dark art of mental ray and i had some questions about it. Usually when i do a render i use the photographic lens and i gamma correct all my textures. But when rendering out contribution maps do i need to delete the lens and remove the gamma correct in order to get the same render out?
Cause i did 2 renders to compare. The first one was straight out of Maya with lens + gamma corrects. And the second i did in passes/contribution maps with the same lens shader/gamma corrects but the result was very different
