Quote - You bring up a point I am not clear on. I understand that there are V4/M4 morphs and I think V3/M3 morphs and such for Genesis, but those only yield figures that look like their old DAZ counterparts. The mesh itself doesn't change. The polycount and nodes for V4's head is different than Genesis, so the old existing morphs I have for V4's face won't work on the Genesis face after the V4 morph is applied. Is that correct?  

Thanks

Correct the old morphs do not work on Genesis even with the corresponding shapes. However, you can use the GenX plugin for DAZ Studio to transfer those morphs to Genesis. I have transferred most of the Generation 4 morphs and some Generation  3 ones without any issues. Once they are transferred they work in Poser, too.
