As I was looking at reference of ram's walking I saw that their scapula moves a lot with every step. Our leg rigs are giving us beautiful movement, but the scapula is left out. The animator has to animate it separately. So
So I took the leg rig we have and plus'd it a little. We now have a tertiary joint chain in addition to our bind, primary, and secondary. This allows the scapula to move with the main ik control, but also allows us to rotate the scapula and humerus independently like we had before.
Leg squash without scapula or humerus rotated.

And here is some reference for your enjoyment. :) Rams are soooo cute!!!
Update: The polevectors put up quite a fight, and after much heartache I had to trash this idea because in certain positions it become unpredictable. It moves beautifully on one plane, but once you go 3d it starts to get crazy. And then if you move the thorax weird stuff really starts to go down.
We still want the scapula movement to look super natural, so we are looking into other methods.
