Thanks TopGun! I like Poser a lot better than working with Bryce. I had such a hard time with distortions in rotating pieces.
I made a few adjustments to the death. How does this look?
I don't think that looks very realistic. If he's falling backwards, his feet should go up into the air as he falls, rather than remaining on the ground until he's horizontal. It's hard to see why his feet should bounce up at the end given that they haven't moved before that - where's the energy coming from? Have a look at some YouTube clips of people falling backwards and you'll see what I mean.
I worked out that the most realistic pattern is this:
(1) The hip flies backwards, while the upper body bends forwards and the feet come up, so that it looks like the hip is leading the movement and the rest of his body is following.
(2) The hip hits the ground.
(3) Immediately, the hip bounces up off the ground, while the upper body and the legs are still coming down towards the ground.
(4) The hip is off the ground and the upper body and legs are on the ground.
(5) The hip falls back to the ground, and the upper body and legs both bounce up off it.
(6) The upper body and legs fall back to the ground.
The way to think of it is that the hip leads the motion. Everything that the hip does, the body parts closest to it do next - the upper legs, the abdomen, etc. And the parts next to those - the lower legs and the chest - do after that. And the most distant parts - the arms and head - do it last of all. It's difficult to get looking right, though.
