I'm wondering if i may be doing something wrong.
Some of my renders can take from 8 to 12 hours to render (& sometimes more). I use a PowerMac G4, Bryce 4 and i render at Normal quality anti aliasing with spacial optimisation high and the size is usually super 8mm (although i would probably like to make it larger for printing).
I don't feel that my compositions are that complex as i rarely use lights or smoke etc.. & after just a few boolean ops it really slows down. I do however like to use some mesh objects imported from Amorphium.
Does anyone have any tips or know of a tutorial that might help & would getting more memory 'significantly' improve the situation?
