stahlratte,

Hello. A user of 3dsMax here.  Wonderful to see someone else is trying this configuration out!

I've actually done a similar job attaching Girl's head to Aiko. Very polite results, and from my experiece there's simply nothing to be done about that neck; those two models just were never meant to be so this problem is a permanent one. Also, I dont own a single morph for Aiko or GIRL so I've no way of knowing how morphs effect the work I've produced.

My problem is trying to figure out what algebra/spell to do to equate those vertices from MAX to Poser. Poser's scale is simply miniscule to every other 3D app! If possible, I'd love to get my digits on that model of your! Hoping for the link as well!
