It's basically the same thing. You need one or two transforms to specify the
alignment of a bone.

But I do. That's kind of the whole point with the technique.

If you mean it'd be a new coding headache every time you have a new model or
skeleton, then you're missing the point. Deforming a skeleton according to
bones is a general technique that, once coded, don't require any additional
coding no matter how different the models and skeletons are. If on the other
hand you think you *do* have a general-purpose solution, then I wish you
good luck coding it.

Again, this should be possible using the same code as for the pants and
sweater.
