4.
Select a file and click Open.
The Motion Capture Conversion Parameters
dialog displays (see Motion Capture Conversion
Parameters Dialog (page 2–1070)).
5. Select the filter options you want and click OK.
The biped adapts itself to the motion data. If
Footstep E xtraction is turned on, footsteps
appear.

savi ng a .bip fi le t hat can be used for any

To import a mar k er file:
Typically,whenamarkerfileisloadedforthefirst
time, it requires scale and pos ition c alibration.
A raw marker file must be loaded, with no
key reduction or fo otstep extraction, to enable
the calibration functions. After calibration is
performed, use Conv ert From Buffer to extract
footsteps and reduce keys.
1. Select a biped.
2. On the Motion Capture rollout, click
Load Marker Name File to load a marker name
file (.mnm).
This step is not required if the marker names in

marker naming convention.
3. OntheMarkerNameFiledialog,clickLoad
CSM Marker File, and choose the .mnm file
from the file open dialog that appears.
4. On the Motion Capture rollout, click
Load Motion Capture File and choose a .csm
marker file.
The Motion C apture Conversion Parameters
dialog displays (see Motion Capture Conversion
Parameters D ialog (page 2–1070)).
5. Adjust the filter parameters and click OK.
Note: Load r aw marker data (No Key Reduc tion,
Freeform) to enable the marker calibration
buttons.
The biped adapts itself to the marker data.
6. On the Motion C apture rollout, click
Show Markers. On the Marker Display dialog,
turn on Show Recogn ized Markers and the
option for On All Objects.
7. Now, on the Motion Capture rollout, click
Talent Figure Mode. Use Non-Uniform Scale or
Rubber Band Mode (on the Biped rollout) to
sizethebipedtothedisplayedmarkers.
Note: This step is optional and should be used
if you need to correct for slight differences
in limb scale between the original talent who
performed the motion and the scale of the
biped after the da ta is imported. For example, if
the leg is too short, sca le the length of the leg in
Talent Figu re mode to adjust the knee position.

Figure mode. Now biped limb positions relative
to the markers can be adjusted.
10. Align the biped limbs to the markers if
necessary, t hen click Adjust Talent Pose to
compute the offset for the entire animation.
11. UseSaveTalentFigureStructureandSave
Talent Pose Adjustment as a .fig and .cal file.

Conversion Parameters dialog when sim ilar
marker files are imported in the future.
