Aye, as for number 7... If you're using Windows XP Pro, like what Erlik said, Bryce will never use the full amount of power, no matter what you do. The only time I've actually convinced Bryce to use full capacity was when I was using the, "Drop To" function on 600+ ground objects. But, even then, it will oscillate between 98 and 99, and never go to 100. If you try to set it's process to "Real Time", chances are you'll just crash, or it will take so long to un-set it that you might as well just reset your machine. But I think you were asking more about render options...? In which case Drac had good answers. There's very few instances when you actually need to use Premium AA modes, but they are a cool function to have around. One way to optimize is to adjust the Ray Depth / Total Internal Reflection in the render options. If you're not using glass or waters or reflections, there's no need to have these higher than 4. If you ARE using transparencies and reflections/refractions, experiment with these numbers. For example, in "endless mirror" types of scenes, you'll want the Ray Depth as high as you can make it, but not necessarily for the whole scene. You can render most of the scene at 4 or so, then plop-render the mirrored parts at the highest level you have patience for... Another thing you can do with shadows, instead of using the Soft Shadows Hope that makes some sense! There's a lot to learn about this program, but don't get frustrated. Just keep experimenting! And have fun, don't waste your time on projects that aren't fun unless someone is paying you for them...
