Hello. Could you help me with a problem I have with a prop? (I'm using Unity 2021.1.6f1) My skeleton hierarchy is like this: It's a biped from 3dsmax. The rig animation type is set to Humanoid. The problem is with the Bip001 Prop1 bone. It has animations too. As you see the bone is attached only to the root bone (Bip001). My animation is set like this: Since the prop bone it's not a humanoid bone I would expect it to have no problems playing it's animation. However Unity rotates the prop bone for some reason and ends looking like this: Setting the rig animation type to Legacy fixes it, but I don't want to use Legacy. Could someone help me understand what's the problem?
