You can use the Motion Analysis Corporation utility to convert motion data originally recorded in TRC format into character studio marker (CSM) format. This allows you to easily map the motion onto a biped.

A MNM (Marker Name) file is needed to determine how to convert the marker names from the incoming data into the CSM naming convention. You can either load an existing MNM file or create a new one using the MNM Creator/Marker Selection dialog.


To convert a TRC file into CSM:

  1. Click the Browse button next to Create.
  2. Highlight a MNM file in the Select Mapping File dialog. Click Open to confirm your selection.

    The MNM file serves as a naming convention reference for the TRC conversion.

  3. Click the Browse button over Convert TRC To CSM.
  4. Highlight a folder in the Choose CSM Files Destination Folder dialog. Click Use Path to confirm your selection.

    After the conversion, the resulting CSM file is saved in this folder.

  5. Turn on Use MNM Filter File.
  6. Turn off Use TRC Filename.
  7. Click Convert TRC to CSM.

    3ds Max opens a Select Source TRC Files dialog.

  8. Highlight a TRC file and click Open to confirm your selection.

    3ds Max opens a Selected Target CSM File dialog.

  9. Either highlight an existing CSM file to overwrite or enter a new filename. Click OK to confirm your selection.

    Your file is converted into CSM format. You can now load it onto a biped.
