11 Use Save Talent Figure Structure and Save Talent Pose Adjustment as a
FIG and CAL file.
12 Load these files in the Motion Capture Conversion Parameters dialog
when similar marker files are imported in the future.
At this point, you can use Convert From Buffer to extract footsteps
and reduce keyframes. Both scale and position adjustments will be
incorporated. Save the motion as an optimized BIP file.
Sliding Footsteps
Motion-capture and marker data typically have keys at every frame. Filtering
motion-capture data reduces keys, making the job of altering or personalizing
the motion data much simpler. You can create your own library of imported
and optimized motion-capture data by saving BIP files for use with other
characters or as part of a longer script in Motion Flow mode. Use a biped that
has no mesh attached to it with Physique. You import the data, adjust it to
your liking, and save it as a BIP file. You can also run standard BIP files through
this filtering process to create loops or to extract footsteps from a freeform
animation.
Motion Capture Import
Footstep motion capture is enabled automatically when importing motion
capture data using the Sliding Tolerance and Sliding Angle controls in the
Motion Capture Conversion Parameters dialog on page 4592.
Footstep Extraction group
The following options are active when Footstep Extraction is on during motion
capture conversion.
Extraction Tolerance Sets the sensitivity of footstep extraction. Biped
determines if the footstep is there by checking that the foot does not move
beyond the distance determined by the Extraction Tolerance value. Smaller
numbers are more sensitive and extract more footsteps. The value is a
percentage of foot length.
The default value is 0.15. Increase this value to 0.2 or 0.25 if too many footsteps
are generated.
