I'm confounded! I'm working on a decent set of crew quarters from the original *Star Trek* and want to get some good renders, but when I do, the image doesn't seem to anti-alias at all, even though I have the post filter size set to 2; I've used this successfully in previous subjects, but all my hard edges here are coming out aliased, regardless of changes in the settings. I even tried anti-aliasing the finished render, but P6 just anti-aliased the preview window, instead.

What am I missing, here?
