Quote - What happens if you export the V4 head and load it into M4 as a morph rather than grafting it on?

That's basically what I did.  I exported the morphed V4 head as an OBJ and loaded it into M4.  I then created a custom morph to smooth the head/neck seam as best I could.  I was using the term "graft" loosely, referring more to the appearance of the result than the actual process.  Sorry if it caused any confusion.

Anyway, this morning I tried exporting the entire morphed figure (M4 with male V4 head) as an OBJ and creating a custom CR2 that uses that OBJ as its base geometry.  This works like a charm as far as the jawline is concerned, but now it insists on skewing the supposedly "zeroed" positions of the thighs and feet towards the default standing position (what you get when you load out-of-the-box M4), even though the OBJ was saved in zero-pose and even appears perfectly zeroed when imported directly into Poser.  Plus, the toes of the CR2 go berserk whenever I pose it.

This is so typical of Poser, LOL!  The solution to one problem only seems to create another.
