I've been trying to create some mattes out of Mental Ray, and I keep getting thin lines where the mattes overlap.
I've done this with RGB mattes, using full 1.0 for R, G, B I've tried with/without "premultiplied" checked...etc.
same thin line.
I've tried using custom Labels...cant seem to get them to show up in Nuke, I've tried custom color...stillt he same.
Can anyone guide me to their favourite current tutorial on how to set this up?
There has to be an out of box option/technique that can make mattes work out of Maya into nuke.
(sadly, all of my production experience in bigger companies have rendered me useless when trying to figure out how to set up my own renders/comps) (those damned TD's make everything work so seemlessly ;)
