Physics) in the Footstep Mode dialog.
8. Click the “handspring” area between the
footsteps. It turns to a solid yellow.
Motion-capture data will replace the keys in
this freeform period.

Conversion Parameters dialog.
The freeform area created in Track V iew is
replaced with motion-capture data. The biped
closely matches the red stick figure during the
handspring par t of the playback.
Inter face
Motion Capture File—Displays the file to be
imported.
Footstep E x tr action—Motion capture data can be
appliedtothebipedinoneofthreeways:
•
None: Freefor m—No footsteps are extracted.
For swimming or flying motion data, footstep
extraction is not necessary. For a traditional
approach to character keyframing, use this
option to keyframe the biped w ithout footsteps
or Biped Dynamics; this is essentially a freeform
animation.
•
On—Extracts footsteps.
Direct ion and style of the motion-capture data
are easi ly edited.
Allows changes to the toe structure of the
biped after import; footsteps will readjust
the character’s mot ion to maintain correct
foot-toe-ground contact at all times, a common
problem associated with motion-capture
import.
Inappropriate “sliding feet” in the motion data
are corrected.
•
Fit to Exis tin g —Fits to existi ng footsteps.
Use with motion data that has both footstep
motion and flying, swimming, falling, or
tumbling motions.
First load the motion data using Perform
Footstep Extraction. Create a freeform period
for the flying, swimming, or falling portion
ofthedatainTrackView,andthenreload
thesamemotioncapturefileusingtheFitto
Existing option. The freeform area is loaded
w ith data from the motion capture file without
the influence of biped dynamics.
Co nversion—Chooses the t ype of key processing.
•
Use Key R educti on—Reduces keys for simpler
key editing.
•
No K ey R eduction—Does not reduce keys. Use
this on files that are already key reduced or if
you want to work with all the data in a raw
motion-capture file.
Note: Marker files imported for the first time
should be loaded with no key reduction or
