Personally, while I appreciate that they attempted to add some new levels of control to the rigging system, the group dependent  method used in Poser is, IMO, antiquated and needs to be ditched. They seriously need to scrap every ounce of that and go with a vertex weight based method. Soooo many hurdles that we, as developers, have to deal with could be alleviated. With a vertex based method, you would not have to worry about the cutting of groups: the figure would be one group. A lot of considerations currently have to be made when modeling for a Poser figure that would otherwise not be necessary if they used a more standard method like vertex weighting. What I would like to see is the current system kept on board only for legacy content, with a system put in place that converts it into weight mapping (I actually had some discussions with folks I've worked with there a few years ago about this exact issue and gave them diagrams describing how the falloff zones could be interpolated into weight maps based on a gradient of their influences), and the primary system convert to something similar to the per vertex weighting we find in apps like Maya, Max, XSI, C4D.. you know... most of the really serious programs out there. This area of Poser has been, I think, deficient for a long, long time and I've spent enough time building Poser figures to have a pretty well formulated opinion on the subject. I also think it's amazing that Poser hasn't adopted any form of IK/FK blending already, sticky IK, stretchy IK, etc. There's a lot of IK/FK functions available in things Maya, Max and Motion Builder that I'm still stunned Poser hasn't adopted yet. Or how about this one: the ability to define whether a morph is calculated before or after a joint rotation. Right now, we're stuck with a one way flow to that particular set of calculations that prevents a lot of morph-to-rotational linkage opportunities that could massively enhance what we can do as rigging artists. I'm not holding my breath on anything for at least a couple more versions though: it will take something coming along that might threaten to steal some of the content market from Poser to drive such radical change. That kind of thing doesn't come voluntarily, from my experience, but I would love to be proven wrong. -Les
