If we open the retargeting tool and select a bone of the model, we can see some options in the detail panel. For the forward kinematics retargeting settings as the uploaded photo shows, we can set the translation alpha value and rotation alpha value to make some adjustments. My question is whether there is a way to set this alpha value in a different direction. For example, making this alpha value have x, y, and z values to control different directions of rotation and translation. Is it possible to do that? Thanks in advance.
