I am trying to add bones animation to my player in MED. When I select Bone Mode, and then click the Create Bone button which creates a bone by placing a red circle on the player, and if I try moving the red circle to a different location, it moves too far per movement segment. Does anyone know how to reduce the movement segment, and get the red bone circle to move in smaller segments, or more like smooth movement instead of segmented movement?

Also, I cannot figure out how to undo a bone when I place it on the player in MED. I try going to Edit/Undo, but the Undo selection is grayed out.

Any help would be appreciated. Thank you.
