Kurt, I hope this thing will be fun to animate but I have to tell you, the rigging has been a real pain. Most of it wasn't too bad but it took me 4 weeks or more to figure out how to rig the feet so they would do what I want them to do.



I came up with a rig that started out as a basic reverse foot rig but it had to have the ability to become a forward foot while also allowing the toes to spread out and move close to each other plus I wanted to link it to the leg IK pole vector so I could rotate the foot outward with the same control that I use to rotate the knee. I felt like I was going insane but I finally got it to work by writing a MEL script, a few expressions and a lot of parenting and constraining.

Here is a clip that shows the rig in action. The control objects on the foot are red. That means they are in "reverse foot" mode so that the toes don't move while the leg raises then, the control objects turn blue which means that they are in "forward foot" mode. This means that the hierarchy has reversed so that the toes can be curled under without effecting the position of the leg.

More to come in the next couple of weeks
