Because I cannot see any bones in figure setup,so I use joint editor,but: 1:oreintation is a bit not correct,why not is from head to tail? 2:this bone cannot be transform,while I try to transform but model trasform,but not bone can be transform

independently 3:I want to add more bone but cannot Thanks.

The orientation is determined by the rotation order - the bone runs along the first axis, the twist axis, when it is created. You want zyx or zxy for rotation order if you want the bone running front to back, depending on which of the other two axes is going to bend the most (the one that will be most likely to reach ninety degrees should be the last).

Thanks cat.
