File menu > Import > Motion Analysis TRC File (*.TRC)
The Motion Analysis TRC motion capture file format represents the raw form (in ASCII) of tracking output. It contains a header section and a motion section.
All tracking markers stored in a TRC file contain global positioning data and do not share parent-child relationships among themselves.
On import, 3ds Max converts the incoming data as either spheres or points, which are named according to the markers names.
You can convert an imported TRC motion into CSM format using the MACUtilities utility in order to map it onto a biped.
Create—Choose this option to build a new set of marker objects. Default=on.
Apply—Choose this option to map the incoming data onto the marker children of the selected root in your scene.
Note: The marker objects must be named to match the imported data.
Selected Items Only—Imports the motion data only relative to the selected objects in your scene. Available only if the Apply option (in the Cloud group) is active.
Root Node—Includes a root dummy on file import. Available only if the Create option (in the Cloud group) is active.
These settings are available only if the Create option (in the Cloud group) is active.
Sphere/Point—Choose between creating spheres or point helpers to illustrate markers.
Size—Sets the sphere diameter or point size, based on your choice above.
All/Range—Choose between using the entire animation range from the motion capture file, or a defined portion.
To/From—These values represent the start and end frames of the defined range. Only available if Range is active.
Offset—Sets the number of inserted empty frames before the imported animation starts.
Set Frame Rate—When on, the frame rate from the TRC file overwrites the current one in the Time Configuration dialog.
