I tried to make this as simple of a demonstration as I could:
The second axis of a generic constraint feels like that it glitches out when it goes near -90 degrees. I’ve added a motor that just pushes it toward that direction, and the result is that it goes clockwise for a little bit and then is yanked back to 0 degrees very quickly. I’d expect it to just go to the limit and stay there. Am I missing something or is this a bug?
