In the OSG OpenFlight plugin these names are ignored when reading, and empty strings are written. As we need these names in the OSG scene graph by our application, I changed the plugin code, so the names are now stored in class "osg::Material" (derived from "osg::Object") by material->setName(); (see "PaletteRecords.cpp, line 195) when reading the file, and written to file by dos.writeString( m.Material->getName(), 12 ); (see MaterialPaletteManager.cpp, line 80). As these names otherwise get lost when reading an OpenFlight file and writing it again e.g. by osgconv example.flt converted_example.flt these changes make the plugin more complete. The changes were made to OSG revision 8425, and were tested by osgconv example.flt converted_example.flt comparing the material palettes of both files inside Multigen Creator."
