@waylow Could a “Limit Rotation” constraint maybe work? If I remember correctly I had this problem when allowing a maximum rotation of 180 degrees so that I set the maximum limit to something like 179 degrees which doesn’t look different to 180 degrees if seen from the distance but avoids any flipping.
@bkohls Really impressive work 👍! When watching your Piero animation in the “.blend” file above or your frosty guitarist here, I feel like I could learn a lot from you when it comes to rigging and animating. Your work is really an inspiration and motivation for me 👍! I find already Piero’s rig absolutely mindblowing with all its dependencies and I still have to create the facial poses and the animation 🤯🥴!
