Thanks much. I was actually using your tutorial as my primary reference, but it didn't spell out the rotation axes (helped a lot with the zone thing, though. So, for example, a thigh would typically be yzx? a shoulder would be xyz? a wing attached to that shoulder would also be xyz? a head on a long neck would be yxz? Also, do you find that you have to make a lot of joints global falloff? I seem to have to do it to nearly everything.
