I had a bit of a break for the holiday which was very, very needed. My brain was starting to freeze up.
Now that I’ve been back, I’m hitting the animation issue again, and I’ve tested a variety of theories about the problem. I think I’ve narrowed it down (in order of likelihood) to an error in how I’m working with the joint constraints. I’m probably asking too much of certain joints that aren’t capable of delivering the motion in SL.
This will require a little reskinning and weighting, but not much, I think. I’m working on that now and should be able to test it in a day or so.
When I have more concrete information about what I did to fix it, I’ll explain it more on the blog in case anyone else has the same issue.
