Free Key allows foot to travel off the ground at frame 20.
Here, Click Set Free Key to set a free key, the foot is off of the ground.
The cycle is repeated to create a walk or run cycle in a freeform animation.
The pivot points are selected by turning on Select Pivot on the IK Key Info
rollout, selecting a pivot in the viewports, turning off Select Pivot and then
rotating the foot in the viewports.
When Join To Prev is turned on, as it is with all planted footstep keys, the
foot pivots at the previous key's pivot point. If you find that the foot is not
rotating around the visible pivot, remember that it is using the previous key's
pivot. In such a case, you must set two consecutive keys with the pivot at the
same location: then the foot will rotate around the displayed pivot.
If you adhere to these rules in creating footsteps in a freeform animation,
then you can use Convert in the Biped rollout to easily change from a freeform
animation to a footstep animation. Note that IK constraints in a footstep
animation are applied exactly the same way as in a freeform animation. If you
examine a footstep animation, you will notice that the foot IK constraints
follow the same rules as for a freeform animation. Footsteps are simply gizmos
