Getting somewhere

I kept changing what bones point at what empties, because the mocap system armature we used has a different number of leg bones, it's really a case of seeing what works best.

I finally got the armature to follow the empties, it wasn't working because I hadn't put the right constraint in. I needed a copy location. It was now following, obviously I need to tidy up the position, rotation, and tracking of the bones, but now I'm getting somewhere.

I looked at an example of a rigged mocap sequence, it wasn't the same armature/bone ratio but just by looking at the constraints I know what is needed. Like the copy location!
