Cute, isn’t he? In fact, when you put him on a timeline, there’s no getting around it – he looks like a lunatic:
Four major things are wrong with this method:
1. It is based on the wrong assumption that the motion of the legs and the way they receive the weight of the body are the most important things to think about.
2. It has no personality, which makes it useless, rather than universally useful like they would have you believe.
3. A, C and E are presented as the main poses – again, based on what the legs are doing. The step, then the transition, then the next step. Those are the leg extremes. However, the torso extremes – its highest and lowest points – are left to the breakdowns: B and D. This is an unnecessary mess. I believe in designing the body extremes first, and then arranging the legs in a way that becomes almost self-explanatory.
4. You can see that he keeps locking his knees. If you do that in 3D, you get the dreaded IK knee snap. What can I say about the IK knee snap that hasn’t already been cried into a keyboard a thousand times?
Looks OK in a still image, but always messes up a walk cycle. It strobes, it flickers, it intersects with the ground in a way that makes you lift the foot way too high, and it just looks silly. Unless you’re doing something very exaggerated, you won’t ever need to bend the toe this far down. Furthermore, there will almost never be a need to turn the back foot so far that the sole faces upwards. That happens in a run, where the kick is hard enough and the back leg takes longer to change direction. In a walk, by the time it lifts from the ground it’s already moving forward for the next step.
