FBX files provide interoperability between most 3D software, regardless of software vendor or computer platform. You can import and export files in this format with
3ds Max.
FBX is the file format originally native to Autodesk MotionBuilder, a system used for creating, editing, and blending motion capture and keyframe animation. You can use it to share data with software such as Maya, Softimage, and Toxik/Composite. You can also use it in building design workflows using software such as Revit, as FBX files contain data relating to model geometry, material textures, lighting, and animation sequences. You can import and export FBX files for use with compatible software, and even link FBX files directly to Revit software.
Tip: Use the Real-Time Exporter to easily export models and animation clips to your game engine.
