I have maya 5 with mental ray which came with it, so far there are a couple of things i have noticed that it can't do. I am not able to render out an .avi in mental ray, i can render a serries of images, but it's a pain to put them together. And i can't use depth of field on a camera. If anyone can tell me if these things just aren't availible in mental ray, or if there is something that i have to do to get them to work, that would be great. Thanks
