Can't we just cut & paste the JP's as text? Looking at the CR2, it looks like you could easily cut & paste just the joint parameters. Maybe someone like Anthony A or Mason could write utility to remove & replace the JP's w/o involving anything else. The JP's wouldn't really even belong to the original dude any more, IMO. So what if the name & xyz center of a limb coincides with his object? The other stuff is generic. That element of the cr2 had little, if anything at all to do with the originator of the geometry . Maybe we could even get a library of JPs going for different animals & people. FYI here's what the joint parameter looks like in the cr2 jointZ lThigh_jointz { name lThigh_jointz initValue 0 hidden 1 forceLimits 0 min -100000 max 100000 trackingScale 1 keys { static 0 k 0 0 } interpStyleLocked 0 angles 45 -45 -135 135 otherActor lThigh:1 matrixActor NULL center 0.067296 0.251407 -0.009911 flipped doBulge 0 jointMult 1 calcWeights }
