The demo reel I am working on this semester also involves the creation of a walk cycle. Below I have listed the tutorial I have been using from Lynda.com. I decided to use the Andy rig for my walk cycle. The rig is extensive, but as I am working I do wish there were additional controls. For instance, the heels of the feet do not have a control. This would have been really helpful in adding anticipation to the beginning of the foot moving and after the passing pose. I have also included a playblast in this post to show my progress so far. As of now I have animated the hips, legs and feet.
