See. I am not sure to be an expert, sincerely. I am very new with P5. anyway, thanks :-) Btw thanks to casamerica ;-)
Well...
In P5 and its Face Room You should start to create your character, save it in "New figure". In that directory you'll find a new cr2 with a new obj file. You'll have to copy them into the P4's New Figure directory. Check the other step... Work your animations in P5. Save Pz3. Open Vue import... Should work.
