File Export Plug-Ins have a new parameter in the method DoExport() to support the export of only the selected nodes. There is also a related new method called SupportsOptions().See Class SceneExport.
Developers should also consider the implications of the new multiple texture mapping channels present in 3ds max 3.0. These will have an impact on what needs to be done to export a faithful visual representation of the scene.
