Motion Capture Conversion Parameters D ialog 1073
footstep extraction to enable the calibration
controls on the Motion Capture rollout.
•
Loa d B uf f er Onl y —Does not apply the data to the
biped, but loads the data to the motion-capture
buffer only. Use this either to comp are your
edited version with the original or to paste
postures f rom the mot ion-capture buffer to the
biped in the scene.
Tip: To compare the filtered data with raw
motion-capture data, use Show Buffer on the
Motion Capture rollout (page 2–1065) rather
than turning off key reduction.
Up Vector—Sets the vertical axis used in the
motion-capture data.
Scale Factor—Multiplies the stored t a lent size by
this value and size the biped accordingly.
Footstep Extraction g roup
Options here are active when Footstep Extraction
is on.
Ex traction Tolerance—Sets the sensitivity of
footstep ext ract ion. char acter studio determ ines
if the footstep is there by checking that the foot
does not move b eyond 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.
Thedefaultvalueis0.15.Increasethisvalueto0.2
or 0.25 if too m any footsteps are generated.
Sliding Distance—Creates a sliding footstep (page
2–1064) when positional tolerance is reached. T his
value is a percentage of foot length. By default, the
foot must slide its own distance (100), before a
sliding footstep is created.
Use this with motion-capture files that contain
sliding feet. A sliding footstep can be created
manually by setting IK Blend > 0 for a biped foot
at a "touch" state key (biped foot first touches a
footstep).
Note: Sliding footsteps display as a footstep with a
line through the center.
Sliding Angle—Creates a sliding footstep (page
2–1064) when rotational tolerance is reached. This
value is in deg rees; the default is set hi gh (360
degrees). Thefootmustmakeacompleteturn
before a sliding footstep is created.
Use this with motion-capture files that cont ain feet
that pivot, as in a dance motion.
Note: Sliding footsteps display as a footstep with a
line through the center.
Only Ex tr act Footsteps Within Toler ance—Tu rns
on Z -axis Tolerance. These controls filter out
footsteps that do not fall within a given range of
the g round plane. Use this when filtering m otions,
such as hopping or pitching a baseball, in which
a foot might come off the ground and remain
sta tionary, but its position is not intended as a
footstep.

Tolerance—Valueisapercentageofleglength.
•
From Z Level—Set a Z v alue (ground).
Flatten Footsteps to Z=0—Moves extracted
footsteps to Z=0. Use this to flatten out minor
differences in the height of the extracted footsteps.
