Tradivoro, i am rendering at 300 dpi for print for some picture i have made, one took me about 7 days to render at 300 dpi for 8x11.25 inch format. The computer used was a P3 at 550 Mhz. Now i am using Bryce 5 and 2 P3 at 866 Mhz, so the render is faster but i never did a render at 300 dpi for the moment. Pleiades
