Apply—Choose this option to map the incoming
data onto the mark er children of the selected root

Note: The marker objects must be named to match
the imported data.
Options group

File menu > Export > Mo tion Analysis HTR File (*.HTR)
The Motion Analysis HTR (Hierarchical
Translation-Rotation) motion capture file format
is an alternative to the BVH (page 3–915) format
because it provides flexibility in data types
and ordering. It also has a complete base pose
specification, which consists of indicating the
starting point for both rotations and translations.
The stored data is grouped by segments; all
motions from the first segment are read, then
those from the next segment, and so on.
The HTR format contains four sect ions: Header,
Segment Names & Hierarchy, B ase Posit ion, and
the mot ion data sec tion.
