Hi, if I understand correctly would you like to fix a spline to a mesh that will modify the spline which in turn will modify the mesh?
sounds a bit redundant to me.
I think it makes more sense to try to fix the spline on the joints...
I think so (but the joints don't necessarily have real positions like the vertices), and I foresee a very boring job. Alternatively, if the small changes to the mesh are not many, I would opt for the morph tag, which is very dynamic in these cases
Thinking about it, there is a trick to "attach" the points of a spline to the joints using an IK spline tag (not the way it was meant to be). I post it for the record
