it is a single frame render.

The deal with the area render sounds like it should work.

My 12 hour estimate to completion was wrong...its still churning this morning and has about 20% still to go....
The bad part with a long render, you're still not sure its going to look like you want. The preview render is surely a lot different looking than what oyu end up with using Firefly. Firefly changes everything...color, shadows, etc..

There was a suggestion thread around someplace. This needs to go in there :)
