Create a walk cycle to test the skinning when it is eventually applied.

Set Keyframes for ALL bones and all three COM tracks:
* Binding pose at frame 0.
* Walk cycle frames 10-40.

I suggest a simple 7-frame cycle:

• Extended poses at 10, 25, and 40.
• Passing poses at 17 and 32.
• Foot heel poses (for good flop) at frames 23 and 38.

It is important to set the bind pose at frame zero, and to always start your film at a frame after that (I recommend 5 or 10) because the Figure Mode bind pose is unrealiable and can be lost, while keyframes at 0 on every bone and COM track will reliably remain available in case the mesh needs to be re-skinned.

NOTE: This tutorial currently assumes knowledge of animating Bipeds in 3ds max, aside form the following terms:

"Bookending" is when two keyframes of equal value are placed at two different times. Any new keyframe on the same parameter between those keyframe bookends will not affect the timeline outside of them, and any new keyframe outside of the bookends will not affect the time between them.

Beacuse of how curves are managed in Biped, Double Bookends are usually needed to get a full pause on a COM. To get Double Bookends simple duplicate the first bookend Keyframe a frame earlier and the second bookend a frame later, for a total of four Keyframes of identical value.
