Did a setting change in one of the latest maya updates for how alpha maps are created (aliased edges vs non aliased)?
The attached file shows how my alpha masks are turning out lately. I don't know which version this started heppening but i'm currently on the newest one.
i used matID and Layer ID and you can see the pixelated edges on everything. Besides the jagged edges all the mask edges are a couple pixels too large, which makes me wonder if there's a new setting i'm not seeing to remove anti aliasing that is turned on by default.
Thanks for the help, this is really causing me issues on some tight deadline projects right now.
