To create footsteps using AutoGrid:
The AutoGrid feature creates objects on a surface other than the default
construction plane. You can use this feature to place footsteps on an irregular
surface.
1 Using any 3ds Max modeling method, create a surface as the terrain for
the biped to step on.
2 On Create panel > Systems, click Biped. In the Object Type rollout, turn
on AutoGrid.
3 If you already have a biped to use, return to the Motion panel without
creating a biped. If you need a biped, create the biped at this time, then
access the Motion panel.

When you activate footsteps, keys are created for the biped's legs and feet,
causing the biped to step through the footsteps. In addition, keys are created
for the spine, arms, hips, and tail (if the biped has one) to make the biped
