Hello,
We're using Renderman for Maya 2.0 and are getting some serious edge mismatch problem.
there are 2 problems here:
1) Please refer to image A, (a composite in Photoshop). The cliff and the ground are 2 separate passes.
There is a thin line between the Mountain and ground, where the alpha is missing - its like a 1 pixel wide gap. I've tried premultiplied interpretation with black in After Effects, also tried the 'black matting' option in photoshop, etc. but with no results.

2) Please refer to image B, (a still jpeg conversion of the Maya IFF output) - its a simple RGB matte. You can see some strange dark outlines around objects where the red intersects the green. It seems the intersections are taking the median color between red and green.
How do I get the alphas to match? is there some kind of render setting? And how do I get rid of this intersection color problem?
thanks in advance!
