What is an FBX file?
FBX (Filmbox) is a proprietary 3D file format owned by Autodesk, originally developed by Kaydara. It supports 3D geometry, textures, materials, animations, bones/rigging, cameras, and lights in a single file. FBX is the industry standard for exchanging 3D assets between digital content creation tools and game engines.
How to open FBX files
- Blender (Windows, macOS, Linux) — Free, with FBX import
- Unity (Windows, macOS, Linux) — Native FBX support
- Unreal Engine (Windows, macOS, Linux) — Native FBX support
- Autodesk FBX Review (Windows, macOS) — Free viewer
