Thanks for the tutorial. Something to do today. BTW, can anyone tell me what the difference is between full render and preview render? When i'm doing renders while composing the scene i keep preview render on because it lets me see things faster. When i go to render out a final image to disk, i'm not sure that i change that on the interface... i haven't been going into the render options to change things before i render a final to disk, so they're probably rendered as a preview. What's the diff?
