I have tried to get the hang of Poser 7 animation layers because I really want to better isolate the animation of individual parts or figures in a scene -- some of my scenes have lots of moving parts, and things get confusing quickly -- but so far nothing has worked the way it should. Yes, I can get a figure to walk and chew gum, but anything else throws my work out of sync. There's supposed to be a new book specifically on Poser 7 animation (I think PhilC is the author) coming out in May. Even sooner would be better for me.
