Out of curiosity, I did a google search for "How to make a clone for Genesis 8" and it lead me to some links on how to do it with V4. Others said the method worked all the way back to Aiko 3!

I imagine to do it, it would be best to start with Genesis because that actor is already in a T-pose.

I would then, possibly, import LaFemme1.obj into Daz Studio. Make a Genesis pose so it matches the joint centers of LaFemme.

Then I would export the posed Genesis as its own OBJ file, to see where It goes from there...
