I rendered out 3 passes out of xsi, and on my ambient occlusion pass i get a white border around everything, anyone know how i can get rid of this? like the border is about...1 pixel , its tiny but it shows up everywhere and is an eyesore. i tried swithing the footage to premultiplyed to strait, but stait just kinda cleaned it up a tad. still there. anyone khow how i get rid of this?

i think u are having alpha premult problem. are u rendering against a white background from XSI? the best is u render ur images with black BG.. anyway..

try setting Interpret footage> premult with the color of the bg (e.g white or black) .. hope this clean up ur alpha..

worst scenario... just use matte tools>choker :) but that'll degrade ur alpha though..
