My main issue still is setting up the correct arm movement with Limb IK-behaviour. After hours of trial-and-error I almost give up. The bending, stretching and flipping of the elbows and shoulders seems impossible to set up. Especially the fact that -to move the puppet's arms- you naturally make a torsion/twisting movement to make an inside or outside hinge movement with your elbow. Is there a way to let Character Animator detect that twist movement? Maybe with a dedicated colored shirt or some kind of stickers on the arms? Without the right movement detection I'm afraid it wil always look a bit strange and unnatural.
