AnimationMentor.com beats out any training that I've recieved from my other schools by far. But in regards to training in animating the dreaded walk cycle, AM has completly obliterated their competition.
At the Academy of Art in San Francisco they showed me the "skating technique" in my 3D classes. This included a 10 minute demo before they threw us to the wolves. Things like weight, hip movement, overlapping motion, and timing weren't even discussed. (with exception to my intro to 2D animation class at the Academy taugh by the Awesome Cora Craig)
Anyway, here's my first successful walk cycle. It's a little weak in the knees still, but I'll be polishing it up in the weeks to come.
This is the second assignment. We had to pose STU in a concerned gesture.
