The problem is that when I rotate the shoulder down so the palm is facing the leg, and then rotate the arm up forward (-90 Z and -90 Y), the splineChain rotates exactly 90degrees for no reason(so the thumb is pointing to the side, not up), and I canīt figure it out why! and itīs killing me! I really wouldnīt post the file here if I could find the solution by myself, trust me, I love challenges, but this one I canīt solve! I have tried pretty much everything but now I need some help!
Please look at the file, i would really appreciate it!/jimmy
