And this shows what happens when I try to move the foot upwards, into a standing position. The "hip" area deforms a bit when the "thigh" is moved, but that's mostly because I cut the figure wrong. I need to remodel the thigh area because it doesn't join the body correctly, and looks off. Anyway, when the foot is moved it doesn't really move at all, it just twists around. The box tracking shows it moving correctly, but the real model does this. It also deforms the parent object (the "shin") even though I didn't move it.
