I skipped through some of the thread this when it got bogged down in "DS" and "you don't know squat" kind of ambling...

Apart from micro-displacement in superfly (needed, to be sure) what about simply able to import a morph at a particular subd level???

I mean, Poser can obviously handle that. It's own morph tool does it, as does one of the external bridges (goz?). Being able to export the mesh at a subd into blender (as obj) then sculpt it, and import that sculpt as a morph ONLY at the specific subd.... Would really go a long way to developing detailed clothing. And body morphs

A dev kit. Or a library of donor shapes.

I mean, for clothing. One thing I find about the donor rigs. They work well enough if the target follows the same overall shape. But the farther you are from that shape, the worse the transfer. Of course. Skin tight needs an HD donor that really just matches the surface of the figure. jeans require something that has a little slack. Pants even more slack. Right?

I might be doing it wrong, but I spend the bulk of my time editing JCMs because they aren't really optimal for what I'm making.
