Ok here we go.. No Bryce does a great job at rendering scenes, although a bit slow..hehe. You may be having a driver issue on your computer.. Check and make sure you update to the latest drivers.. DirectX 8.0, OpenGL drivers for you card, things like that. Also a thing you might try is to rerender the scenes that you know looked good and see what happens, do they look the same or worse. Once they are done save them and look at the two pictures on a different machine. If they are truly different...?? I got no idea why, the rendering engine should not be effected by the machine its on good or bad, the only thing that will make a difference will be the speed it renders. Hope that helps.
