About joint orders ... From exprimentation - I figure that the joint rotation order is determined by the order of the rotationX/Y/Z in the channels section of the particular actor in the cr2 file ??? If you want to rotate in XYZ, you should set the rotation order in reverse i.e. rotationZ, rotationY, rotationX in the cr2 file . I don't think that the order of the jointX/Y/Z or twistX/Y/Z matters . They just seem to indicate which is the twist axis . About joint zones ... I think the joint zones were created originally for simulation of tendons . But they don't seem to work effectively that way . An easier way to adjust bends is to adjust : 1. the start/end bend angles in the joint editor by directly moving the bullseye cursor of the angle handles in the poser figure . 2. the bulge values in the joint editor panel .
