Keying out different colors in 3d renders

Postby thanulee on 06/5/2017, 10:00 am

Hi, i use a lot "set matte" when i have pure R G B values in my id passes from 3d. There are times though that i have various colors in ID pass.
How do i key out those effectively without leaving artifacts on the edges? thanks

How clean it is depends on how anti-aliased your ID passes are. Anyway, the "obsolete" Color Key effect is probably what you want. You'll need to invert the alpha channel after you use this to get what I think you're after. :)
