hi all
was wondering if anyone has a solid idea on how to spit out an alpha that is unpremultiplied directly on Mental Ray
there is a quick way for maya render but for MR looks more likely that the buffer are my solution...
any idea or setups to share?
tnx

There is no such thing as an "alpha that is unpremultiplied." Only color can be unpremultiplied.

There is a Premultiply checkbox in render globals, mental ray, framebuffer attributes.
