(Not trying to be accusational here, trying to address Bobbie's questions) .. OK ... when DAZ created V3, they spent a lot of time developing joints that would work the best with V3's shape and grouping. They reached the values they did through a LOT of painstaking work. Those were the settings and values and zones that made V3 work like V3 for the shape of V3. Now ... earlier threads about Renda showed her mesh and V3's mesh superimposed one over another. There shapes were very nearly identical. Meaning, that "the best" joints for Renda would also be those created for V3. But, it appears that the initial release of Renda used JP's that were DIFFERENT than V3. That is why she didn't bend very well. The reason that there are other figures that are out there that bend fine without V3's joint parameters is because they aren't shaped exactly like V3, and therefore would need their own custom joint parameters.
