I’m working with a rig generated by BlenRig and was wondering why a particular bone rotation is using ZXY Euler and can’t be changed. The dropdown showing the rotation type is purple. I am able to click on the dropdown and see the other options, like Quaternion (WXYZ) and XYZ Euler.
Any idea of what’s going on here? How can I change the rotation type? Other bones in the rig allow me to change the rotation type (and are not purple).
