What kind of file is a .csm?

CSM is a CharacterStudio motion-capture format. It stores ASCII marker names and frame samples that can drive a compatible character rig; it does not contain the rig's mesh or materials.1

How do I open a .csm?

Use 3ds Max Character Studio and apply the motion to a matching biped or marker setup. Check frame rate, marker naming, and coordinate conventions after import.

Poly support for .csm

Poly recognizes .csm as model/x-csm, indexes its filename, and can use visual similarity when a schematic rendition is available. Available motion and scene counts appear in details. CSM contains marker data rather than a finished character; readable data can receive a schematic or skeletal rendition for agent interaction.

Working with .csm files

Keep the original and export a copy through a format-aware tool when moving to a scene format. Verify marker mapping and timing after conversion.1
