Scott I think I could cover them all (apart from Motion Blur) in one post. I just don't have time at present but I will see what I can do..no promises though. Idea for future contest: using the new features of DS4.5, such as instancing, motion blur, push modifier, and geometry shell. Some of these I've attempted without much success; others I've yet to try because I don't know where to start.
Don't quote me on this but I think we would like to keep the learning in general terms and not get too program specific.
