Maybe I won't do that.

The very first time I use nCloth to do something it was meant for, I discover it's not so good at it.

There's a couple fixes I can think of. I'll either have to rig the armour attached to the body, or perhaps cheat it with a deformer. Either way, I'll have to re-rig her hands again anyway; I just discovered that her fingers won't move at the first joint, which makes sense considering how I rigged it, but it looks really strange.

Maya's FBIK solvers aren't totally solid either, but they do the job most of the time. Lips and eyelids I'm using spline deformers rather than blend shapes, and her tail is a IK spline solver. No problems there.
