As a prediction, the first one is usually crap. The second or third pass is usually much more accurate. And yes, 14 lights with shadows on would make a render long. BTW, DO NOT save as JPEG from Bryce. Its JPG algorythm is always crap. Save the BMP and then convert in a 2D program. Apropos the passes, I've got something that's been rendering off and on since the beginning of Novemeber. 3700x2700, DOF with 64rpp. But I also counted at least eight passes and it's still rendering. Usually, Bryce makes only four passes. Possibly it's a bug, because I leave it to render when I go to work, stop and save when I get back, and then resume the render either the following day or a couple of days later. I don't see any visible difference during the last couple of passes.
