One problem I have had more than once is that foot targets become disconnected. I move them and nothing on the model moves. I seem to remember that one time I fixed the problem by opening the basic skeleton model and dragging the foot targets from the skeleton model to the model with the foot target problem. That was couple of years ago, and I have forgotten what I did exactly. I am not able to do a repeat performance. Does anyone know a slick and easy way to reestablish foot targets?
Foot targets, by the way, seem to be the most vulnerable part of the skeleton. If something goes wrong with the skeleton in my brief experience, it is usually that the foot targets cease to work. I don't know enough to understand why this happens. What is there about foot targets that makes them more delicate?
