Importing HTR/HTR2 Files 625
The header sec tion contains global par ameter
information:
•filetype
•datatype
•fileversion
•numberofsegments
•numberofframes
• data frame rate
• Euler rotation order
• calibration units
•rotationunits
•globalaxisofgravity
•bonelengthaxis
•scalefactor
HTR2 is nearly identical to HTR, except that
thedatafromthemotionsectionisorganized
differently in order to better suit a streaming data
input (a sample-major ordering is used to present
the motion information).
On import, 3ds Max constructs a FK hierarchy
rig from the incoming data. The resulting bone
skeleton is linked to a dummy object named after
the H TR file.
Inter face
Skeleton group
Cr e a te —Choose this option to build a new b one
skeleton from the incoming data. Default=on.
Segment Size—Set this value to modify the scale
factor for the weight and heig ht of all b ones from
the motion capture data. Only available if Create
is active.
Note: T his does not change the skeleton’s scale.
End Effectors—Tog g le t h i s opt ion to i mp or t end
effectors (page 3–1027)
from the incoming data, if
they exist. Only available if Create is act ive.
Apply —Choose this option to map the incoming
data onto the children of the selected skeleton root
in your scene.
Keyframe Options group
B ase Position— When on, imports only the keys of
thebasepose.
Animation—When on, imports all animation keys.
Default=on.
Rotation Controller group
Euler/TCB—Choose one of the two rotation
controllers (page 2–312)
to apply to the imported
data.
Time Options group
These options (except Set Frame Rate) are
only functional if the Animation option in the
Keyframe Options group is enabled.
All/R ange—Choose between using the entire
animation range from the motion captu re file, or
adefinedportion.
From/To—These values represent the star t and
endframesofthedefinedrange.Onlyavailable
if Range is active.
Offset—Sets the number of inser ted empty fr ames
before the imported animation starts.
