I'm trying to snap the tail of a pose bone to a vertex in another mesh. When I hit R or G to start moving the bone, it snaps just fine, but rotates the bone approximately 90 degrees away from the point it's snapping to. I would like the dotted line it's using for snapping to go from the head to the tail of the bone.
Desired snap (simulated by holding "Ctrl" while rotating)
I'm sure this is a coordinate system feature, just not sure how to work with it.
