Can someone please tell me how to reposition an axis or pivot point once the character is set and has bones? Sometimes the center axis is in the wrong place and I want to move it or pivot it a different direction or rotate it so I can move the bones in another direction.
I know there's a way I have seen it done I just forget where I saw it or how to do it.
For example: I have a sitting man brought in from modeler. I want to move his shoulder, the rotation is on the wrong axis, can I move the rotation axis so that I can rotate his shoulder and the rest of his arm would lift up or down?
Thank you in advance.
