"Yeah it's called RAYTRACING, and is far superior to the opengl instant pictures for morons option" Yes I realise that raytracing is superior. Thanks. But I think OpenGL is not moronic, but a useful temporary way of rendering. The clear implication in your otherwise helpful reply is that only "serious", macho, in-the-know people use raytracing. Is that so :) Thanks all the same for the tips. L
