I'm inclined to think that weight maps are too radical a feature. It's pretty obvious that a lot of work has been done on the interna;ls to support multiple cores, and escape the memmory-hog nature of earlier versions. And these changes were needed, IMHO, to keep Poser worthwhile when Vista comes out. From the programmming POV, there's some major effort in that. But then it occurs to me that they're a sort of displacement map, with the effect varied with joint position: a sort of displacement map equivalent of a JCM. And if that is what they are, would a more versatile programmming system to link parameters would be the general case. Think about this: the ability to have something more complicated than a simple multiplier to link a morph to another parameter. Perhaps the morph doesn't go negative, and the starting-point is offset from the zero-point of the controlling parameter. And if you can do that to the displacement value applied to a specific material, you don't need a high-polygon count around a joint for such things as tendons. Yes, that's a rigging iumprovement, and it could be horribly complicated to set up well. And there's one other area where there are possibilities. People are, to some degree, squidgy. Prod them, and the surface changes shape. Think what a system to handle that could do--collide and deform.
