Hi, I'm Clarissa, And i've been having a little trouble in bryce 4 for mac. I've created a scene that's about 55 megs and i'm on a G3 but it takes hours and hours of rendering, and seems to just stop after some time.... could anyone help with maybe knowledge of a program, or something to make my rendering work??? Also is it possible to transform an object into a lightsource? eg. change a cylinder into a lighted clear cylinder?
