An .fbx file is a collection of assets, animation, and MotionBuilder settings. Assets may include a model created in another 3D software package and exported using an FBX plug-in, animation data saved using MotionBuilder, or any other assets created and saved using MotionBuilder including lights, cameras, control rigs, and so on.

This chapter describes the more common file operations within MotionBuilder that deal with adding, loading, merging, and saving assets from .fbx files, as well as loading and merging keying group data. The chapter also also discusses importing and exporting full scenes and importing and exporting animation or motion capture using other data file formats. Preferences specific to saving or backing-up .fbx files are also discussed, as well as topics on batch processing, audio, and version control.

To find out what is supported when exporting from MotionBuilder and then imported into Autodesk 3ds Max or Autodesk Maya, see the MotionBuilder FBX Map FBX Interoperability Chart at: http://www.autodesk.com/fbx, on the FBX Documentation page.
