bool r = LoadScene(gSdkManager, lScene, ImportFileName);
if(r)
        UI_Printf("------- Import succeeded -------------------------");else
    {        UI_Printf("------- Import failed ----------------------------");// Destroy the scene
lScene->Destroy();
return;
}
    UI_Printf("\r\n"); // add a blank line    UI_Printf("------- Export started ---------------------------");// Save the scene.
r = SaveScene(gSdkManager,
lScene, // to export this scene...

pWriteFileFormat, // using this file format.
false); // Don't embed media files, if any.
    if(r) UI_Printf("------- Export succeeded -------------------------");    else  UI_Printf("------- Export failed ----------------------------");// destroy the scene
