FBX Import / Export

The FBX file format, which was originally developed by Kaydara and currently owned by Autodesk, is supported by most major 3D applications, including of course Autodesk's MotionBuilder software. FBX files are capable of storing not only geometry (and Splines) but also material and texture data, animation, light and camera (incl. stereo cameras) data. Note that not all object data (e.g., all Cinema 4D light parameters) can be transferred but only data that can also be interpreted by other applications.
