An MSM file may also be a motion data file used by video games developed with the UbiArt Framework, including Rayman Origins and Child of Light. It stores animation or motion information the game references to animate game characters, objects, or visual effects appearing in gameplay. MSM files may include keyframe animation data, transformation instructions, or movement sequences tied to specific game events.
More Information
UbiArt Framework is a game engine created by Ubisoft that powers various 2D video games. The UbiArt engine reads MSM files during runtime to display smooth animations and to coordinate the motion of visual elements based on player interaction or scripted events.
NOTE: While UbiArt Framework was prominent in the 2010s, Ubisoft no longer develops it.
How to open an MSM file
MSM files are not intended to be opened or edited directly by players. Instead, the game with which the files are packaged accesses them when loading animation and motion information.

Just Dance Motion Synchronization Map

An MSM file may also be a motion data file used by several older entries in the Just Dance series developed using Ubisoft's UbiArt Framework. It contains motion, synchronization, and mapping data that define specific dance moves, including their timing and structure. During gameplay, the engine references MSM files to determine when and how a player's movements should be evaluated, ensuring synchronization between the on-screen choreography and the player's actions.
More Information
The MSM format used in Just Dance is similar to the format used in MSM files by other UbiArt Framework titles, such as Rayman Legends and Child of Light. However, Just Dance uses a customized version of the UbiArt Framework that includes support for rhythm- and motion-based gameplay.
MSM files are integral to the game's scoring and choreography systems, with each MSM file corresponding to a particular dance move or sequence. When the game loads MSM files alongside a .WAV or .OGG song and SCD choreography script, it parses the MSM file in real-time to determine the move the player is supposed to make at the moment for instant feedback and scoring. For example, in the "Tribal Dance (Katana Version)" routine, MSM files like tribaldancealt_nunchku_pose.msm are used to represent specific poses or movements.
NOTE: MSM stands for "Motion Synchronization Map" or "Motion Sync Metadata."
How to open an MSM file
MSM files are not meant to be opened or edited directly by players. Instead, the Just Dance game with which the files are packaged accesses them when motion information.
Modders and developers working with Just Dance may attempt to modify MSM files with fan-made tools to change scoring difficulty, create custom routines for existing songs, and sync custom choreography. However, no known programs fully support the opening of MSM files.
