Speed—
Displays the number of units the biped
will move per frame. This changes in response
to changes in the other parameters but cannot b e
adjusted directly.
The follow ing two par ameters are only enabled
when Auto Timing is off. You can use these
parameters instead of Auto Timing to cont rol the
speed of the forward motion over the series of
footsteps.
2 Feet Down—Specifies the number of frames
that the left and right footsteps will be on the
ground during the jump. The higher the number,
the longer the pause between each jump and,
consequently, the slower the speed of the jumping
motion.

Airborne—Specifies the number of frames the
body will be in the air during the jump.
The higher the number, the longer the biped hang s
in the air for each jump and, consequently, the
slower the speed of the jumping motion.

When you click Convert on the Biped rollout of
the Motion panel, a Convert To dialog displays:
Convert to Fr eeform or Convert to Footsteps,
depending on the animation method of the
currently loaded motion. Use Convert to Freeform

Note: By default, Jumping or airb orne periods
between footsteps are calculated by character
studio based on gravity st rength (GravAccel) and
time between footsteps. Biped elevation during

when converting to freeform from footsteps
(unless you create a vertical COM key in the
airb orne period in the footstep animation), a
freeform animation uses spline interpolation for
the center of mass position and does not account
for gravity. Elevation in airborne periods is
restored if you convert back to footsteps.
When to Use Conver t
• Use Convert after using Save Segment in
Motion Flow mode to save a script as a .bip
file. Exit Motion Flow mode, load the .bip file
and click Convert to extract footsteps. Save
Segment applies IK Blend values of 1 to the
biped foot keys for the keys at footsteps. If
a freeform animation is part of the script in
Motion Flow mode, and you want to con v ert
the entire scr ipt motion to footsteps, then use
theSaveKeysateveryFrameoptioninSave
Segment and use Load Motion Capture File
on the Motion Capture rollout. This will allow
you to extract footsteps using the proximity
method.
• Use Convert if you are working on a footstep
animation and want to switch to a fr eeform
animation.
• Use Convert if you have started a freefor m
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
