Thanks :-)

Is the point of most of these morph-based (?) bodyshape fixes more to address joint bending issues and distortions than anything else?

On that basis then sure, I can understand that the re-rigging, as an integral part of the weight mapping, should presumably sort all this sort of stuff out on its own... and then I shouldn't need them, if I'm adopting V4WM... which I am.

As I understand it, the V4WM injection corrects and improves the way that the existing bodyshape mesh behaves when it bends and flexes?

Does it actually somehow reshape and refine the base (static) bodyshape mesh a little too?

I guess the latter is more about how anatomically "realistic" (or whatever) a shape  the original figure's base mesh itself is... and that's something else altogether isn't it? As in aesthetics rather than functionality perhaps... these crossover I guess though.
