Ok, here's my issue. I have an oblong shield that once of my characters uses. The idea I have for the shield is that when not in use it is worn along the length of the arm, from wrist to shoulder, and when in use it swings around 90 degrees so that it lays across the arm like a normal carried shield would. My question is would this be possible to achieve or would the rotation script not function properly when attached to an avatar rather than being in world?
