Fantastic work Chris. But just to clean up some facts.

I found out that I was to hasty with V6 and the fitting room. - After fiddling a little more with it I found out that it actually works with V6. You have to export it as Cr2 from Daz. (a one time operation). Then before you go into the fitting room dial up the V6 morph to 1 and then check for "Keep Deformations in the create session dialog.

So there are no difference between Dawn and V6 when it comes to fitting in with old cloth, the products have to compete by quality alone. Dawn may be better but V6 is part of an advanced ecosystem.

We live in interesting times.
