The TRC motion-capture file format by Motion Analysis Corporation represents the raw form (in ASCII) of tracking output. It contains a header section and a motion section.

Application Menu > Import > Motion Analysis TRC File (*.TRC)
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.
To map TRC data onto a biped, you can convert an imported TRC motion into CSM format by using the MACUtilities utility.
Cloud group
- Create (The default.) Choose this option to build a new set of marker objects.
- 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.
Options group

- Offset
- Sets the number of inserted empty frames before the imported animation starts.
- Set Frame Rate
