I’ve already tried that checkbox, doesn’t help the issue at all. I feel like it has to do with rotating somehow, because it sometimes it only happens if I turn my head left or right AFTER looking straight up. It would happen once or twice early on, but now its all the time and it makes it unplayable. Its also definitely not collisions as I’ve tried with no collision set. Its like something is telling it to bend the body over if the angle of the head goes a certain way.
And yes I use the calibrated body structure to save poses.
