Well, for clothing that you want to conform to V4 with obj2cr2, will that work? This is on place where how you export from Blender determines how PhilC's thingie is going to behave, I think. V4 has to be in her relative place in Poser. No idea how scaling her is going to behave.

I suppose on could have a scaled-up version of V4 in one layer in which you actually make the clothing, then you scale it down and fit it to you pristine, untouched, purely imported version in another layer when you have it all done and don't need to take advantage of Blender's hi-tech stuff anymore.

Any thoughts on this babble from the sickbed? (pounding headache and Advil is only turning my brain to mush so I don't notice it so much...)
