Procedure
To conv ert a n a i r b orne pe r i od t o f r eef orm mod e:
1.
Create a footstep animation with at least one
airborne period, and activate the footsteps.
For the simplest method of creating a footstep
pattern with an airb orne period, s ee Creating
Footsteps Automatically (page 2–862).
2. Access Track View by choosing Graph Editors
menu > Track View - Dope Sheet f rom the
3ds Max menu.
3. Expand the footstep key display for the biped.
4. Right-click the footstep key display area. The
Footstep Mode dialog appears.
5. In the Footstep Mode dialog, choose the Edit
Free Form (no physics) option.
In each airborne perio d in Tr ack View, a hollow
yellow box appears.
6. In the Track View footstep key display, click
inside the yellow box for the airborne period
for which you want to suspend gravity. This
fills the yellow box, indicating that vertical
dynamics are suspended for that period.
7. Play the animation. The biped uses vertical
dynamics during al l footstep motions except
the freeform p eriod.
No ver tical dynamics during freeform period, then return to
vertical dynamics during ne x t airborne period.
Note: If you activate footsteps after a freeform
period has been set b e tween footsteps, the
biped might skip footsteps at one end of t he
freeform period. For this reason, you should
activate footsteps before setting up a freeform
period.
8. During the freeform period, animate the biped
andsetkeyframesasyoulike.
To edit footstep timing after creating a freeform
period, you must choose the Edit Footsteps
option in the Footstep Mode dialog.
