Reply To: Mystery rig with mystery bones

I’m confused and probably missing something obvious. With the door bone(s) orientation, connected to and relative to the root bone, I don’t see any way to align either the X or Z axis with the world Z-axis using only the Roll parameter. Screenshots attached.

I like where you’re headed with this, I’m just not executing it very well. Thank you for your continuing help! 🙏🏻
