I wish I knew also ...I get a blue screen fatal error trying to render the MIl Dragon in a new window ...even with no textures or bumps on a 1.4 Athlon with win98se 30 gigs free 512 ram and a geforce2 vid card...I will be careful what I purchase including P5 because no one seems to be able to come up with a fix for it..( I can export to bryce with all textures and bumps and make any size document I want no problem..but sometimes its a hassle when your trying to make a scene and want to be able to adjust the poses.....oh well ...good luck
