Quote from J Walton :
Interesting, Andrew. Does that mean I would get higher render quality using Preview than I would with a standard render? Is it really Maxwell-style refinement that just keeps going and going?
I figured it would keep refining until it matched the quality of an F9 render.
Do Preview renders allow for passes, or just Beauty?
Yes, it will exceed the quality of the standard render, if given enough time. It pretty much just keeps going and going - it's technically limited to 16384 AA samples, but that's not much of a limitation :).
You can only do one pass and output at a time, but you can do any pass and output. For single beauty shots, it's a much simpler way to work than tweaking settings. If you need to do comping or serious post-work, F9 (offline) rendering is still the way to go.
