the beauty of Bryce 5 on OSX is that it does multitask a consderable advantage over OS9 in that you can set the render AND still use the computer for other stuff, word proc, surfing etc, I always found it apin in the arse when rendering meant you were locked out of the computer. It does crash when you try to import .obj files but the workaround is you have the mesh (.obj) the texture descriptor (.mtl) and all the texture files in the same folder. That works fine. OSX is a thing of great beauty
