Cimerone, I understand that rendering Poser figures in Bryce can be a worthwhile cause, but did you try just rendering a screen-size image first? "This better be good" implies you're not sure, not to be critical but seriously you DO NOT want to wait five days for a possibly shitty rendering. That's like four days downtime, minimum... Is it for print? That's the only reason to render so high, and honestly rendering to disk on such an image may not make it any faster for you. What kind of machine are you using? Specs might make things easier for us to analyze the "sitch", and also, have you tried Lightning? It's free, if you have Bryce 5 I highly recommend it... Still, post a screenshot or a smaller image and maybe we can cut your render times down...
