As someone who has been animating quadruped walk cycles for almost a decade, I assumed that biped and humanoid walk cycles would be fairly straightforward, and one would assume that recreating one of the first things we ever learn to do in our lives would be simple. It wasn’t. They’re a very mechanical process that accumulated into a simple looping animation. To begin, I looked at several tutorials for 2 Dimensional Walk Cycles:
I then turned to the Bible of Walk Cycles, the Animator’s Survival Kit, to gain further insight on the mechanics of walking.
