Opera; Yes, it would require some recoding of Poser, which is most likely the reason it hasn't been done yet. As I don't have access to the higher end programs that use weightmapping I can't say how involved it would be, but I do know that there is more than enough difference in behavior that the current scheme could co-exist side by side, just because there is no commonality between the two rigging systems. As for characters....well, Pixar proved you can dual rig a character quite handily (Elastigirl in The Incredibles; the stretching effect was controlled by a different boning rig, and they switched between them on the fly in rendering and animating. A Poser level dual rig couldn't be quite so exotic, but it could be done). The hope here is for Poser 7. CL did basically what they said they would do for P6; fix and stabilize (minus the OpenGL problems), saving any major code work for the next release. With the support of E-Frontier, this would probably be the time to develop a new boning system. And for the users to begin nudging for same. Whether or not a figure mesh needed recutting...or any cutting at all...would depend on exactly what they did and how. It probably could be done without recutting...or at worst,simply fusing the figure obj into one integrated unit with the correct winding order, and having two obj's; one for the old bone system, and one for the new.
