Short description of the FBX format
FBX (Filmbox) is a proprietary file format (.fbx) developed by Kaydara and owned by Autodesk since 2006. It is used to provide interoperability between digital content creation applications. FBX is also part of Autodesk Gameware, a series of video game middleware.
It provides sophisticated and rich 3D graphics and is very popular within 3D modeling and rendering software such as 3DS Max, Maya, MotionBuilder, Mudbox, and Unity.
