Pose Adjustment to save a size and position
offset to a FIG and a CAL file, respectively.
Load these files in the Motion Capture
Conversion Parameters dialog when you
importsimilarmarkerfilesinthefuture.
At this point, you can use Convert From Buffer
to extract footsteps and reduce keyframes.
Both sca le and position adjustments wil l be
incorporated. Save the motion as an optimized
BIP file.

Load Motion Capture File—Key reduce and
extract footsteps from raw motion-capture data.
Load BIP, CSM, or BVH files. After you open a file,
the
Motion Capture Conversion Parameters dialog
(page 2–922)
opens. Following are descriptions of
settings in the Open dialog.
Files of t ype—
• BIP—Filters the raw version of the
motion-capture data that ships w ith
3ds Max. These are in a BIP format. Filter
standard BIP files to convert footstep animation
to a freeform animation; extract footsteps from
a freeform animation; and to loop a BIP file.
•
BVH—BioVision motion-capture data file.
Cont ains the “ac tor’s” skeletal and motion
information. Once the motion-capture data is
filtered and adjusted, save it as a BIP file for
later use.
•
CS M—Imports a character studio marker file
(ASCII format file). Optionally, load a Marker
Name file (M NM), a Talent Structure file (FIG),
and a Talent Pose file (CAL) before loading a
CSMfile.Markerfilesshouldbeloadedwith
no key reduction and no footstep ext raction to
enable the calibration controls.
Restructure biped to match file (BI P files only)—Tu rn
ontochangethebipedstructuretomatchthe
structurestoredintheBIPfile.Thefileloadswith
the stored biped str ucture. This is an Open dialog
option.
This option is unavailable when you load a BIP file
intoacliporontoabipedthatisinEditClipmode,
becausealltheclipsinthemotionflowwouldhave
to be adapted.
Note: CSM and BVH files always load with the
biped structure stored in the file.
SetloweststartingfootheighttoZ=0(BIPfiles
only )—
SetstheloweststartingfootheighttoZ=0.
This is an Open dialog option. Default=on.
In 3d s Max, the height of a motion clip can be
retained. This is impor tant if you want to retain
the height of a motion clip for motions adapted to
characters of different sizes. If, for example, the
character is jumping off a rock, and you want to
retain the Z position of the character , you would
turn this option off. Leave this option off if Motion
Flow motions must be blended that begin and end
at different heights, such as three clips that have the
character mounting a bicycle, riding the bicycle,
and dismounting the bicycle.
Turn ing off this option can, however, cause a jump
in the motion during motion flow transitions.
Turn this on for smo oth transitions in Motion
Flow mode. If adaptation takes place, the height is
set so that the lowest foot at f rame 0 star ts at the
Z=0 height. This lines up clips along the Z-axis
and creates smooth transitions.
