Mike, I couldn't find the screen grab or roto reference in steps 5 & 6. Kinda sounds like a Tim Allen tutorial.
I think the 3dbg.tff is in the 3dbg.zip file that you can download near the bottom of that first page that the link takes you too.
It is like learning another language, isn't it. I figure it's good exercise for the 2 brain cells I have left.
Someone else will check in with the other info for you.
