Remove footsteps using IK keys:By editing IK keys, you can remove footsteps as well as add them.1 At frame 45, select the Bip01 R Foot object in the viewport, then
set a free key.2 At frame 48, set a free key.3 At frame 54, set a free key.NOTEThe body vertical position is modified. The biped now floats up into
the air at frame 54.4 At frame 60, set a free key.
The footstep disappears.
There is only one IK key left. With no IK interval defined, there is no
duration, and therefore no footstep. The result is that the biped hops
between footsteps 2 and 3.
The animation could be made more realistic by adding arm movement
to the hopping steps, or by creating a freeform period for the hop, then
adding poses for a crouch, spring and landing. The point of this lesson,
however, has been to demonstrate that footsteps can actually be created
or removed by changing the IK keys.760 | Chapter 5 Character-Animation Tutorials
