This section expands on a primary function of the FBX SDK: importing and exporting scenes.
Importing and exporting data is performed by the FbxImporter and FbxExporter classes respectively. The FbxIOSettings class is used to specify the scene data which is imported from or exported to a file. Custom file formats can be imported and exported by creating a custom FBX SDK I/O Plug-in derived from FbxPlugin.
