What is a BUM file

BUM files mostly belong to Unity/Gamebryo.

BUM files store 3D model data used mainly in game development.
They hold information such as geometry, texture mapping, and animation parameters that game engines use to render objects in real time.

In one use case, these files are created for the Gamebryo engine, representing detailed 3D models.

In another case, they are used with the Unity game engine, where they can include both static models and animations. For more info, visit Unity.

The format is internal, meaning it is tailored for the engine’s asset pipeline and not intended for everyday image or text editors.

FilExt.com note: To view or edit a BUM file, use tools and importers provided by the game engine or dedicated 3D conversion software. Always keep a backup before making changes.
