■ Use Convert if you are working on a footstep animation and want to switch
to a freeform animation.
■ Use Convert if you have started a freeform animation and want to covert
to a footstep animation. In order to convert a freeform animation to a
footstep animation, the file must be properly set up by locking the feet to
world space using IK Blend before converting to footsteps. When creating
freeform animations, you should set your leg keys to IK Blend=1.0 during
the periods you want the feet to be planted, and set the move keys to IK
Blend=0.0. This will insure that the feet are locked and rid of unnecessary
foot sliding as the body is moved. When converting, if the leg keys have
been set up this way, Biped will extract footsteps during any duration
where IK Blend=1.0.

NOTE Converting footsteps to freeform creates foot IK Blend values of 1 for the
biped feet for the original footstep keys. This simplifies keyframing by putting the
feet into world coordinate space, which prevents them from sliding when the
biped is moved. These foot IK Blend values are also used when you click Convert
(on the Biped rollout) to convert back to footsteps.
