Actually Judy is a reworked Posette, the mesh subdivided and made into a new figure. Given the name Judy in P5, the community called the P4female posette. All poser figures up until Poser 5 are based off the old Zygote models. There are old threads between Daz/CuriousLabs here in the forums with all the dirt and scandal that came with Poser 5. Jessi in Poser 6 is a new figure and not a reworking of old Zygote models. efrontier contracted out for the new Jessi and James models.
