What is a PMM file?

PMM files mostly belong to MikuMikuDance. PMM files are project files used by MikuMikuDance, a tool for creating 3D animations.
A PMM file contains all the data required to set up an animation scene.

• It stores scene settings such as camera angles, keyframes, and other timeline information.
• It holds details that let you adjust models and effects during project edits.
• It is not a final video but a workspace that the software uses to rebuild the animated scene.

The file is also known by its alternative name: Polygon Movie Maker file. This alternative description points to its origins in handling polygon-based models and setups.
