I thought that the two characters below had identical armatures… apparently, I was wrong.
This is the jawbone for each:
As you see the axis displays are at opposite ends.
The one on the left works correctly.
How can I make the one on the right the same?
Thanks
Hi Cal, in the armature’s viewport display there is an axis position slider. with the slider you can set the axis to the root or tip.
Bones always rotate on the root anyway, so I do not know how the axis position will effect the movement of the bone, I was not aware of this slider before.
For the y axis rotation you can set the bone roll option. Changing it now might change things, if you already have the weights etc set. You may have to UN-parent the bone and redo the parenting and weights afterwards.
YOU ARE MY HERO!
However, I wonder how it got reversed… oh well… “things that make you go ‘hunh?’”
Thanks so much!
I often have the same dilemma “how did that happen!” 
I have looked it up and I think that the axis “position” slider is just a viewport visualisation thing and does not change how the bone works.
Yep. But, I didn’t know about it until now. So, I learned something (or two) new today!
Thanks again. and turn all controls to 11 !
