 The example world contains only a sun and the Static Map plugin. A `ground_plane` model is not needed as the plugin will be generating and inserting the map model into the world at run time. Before launching this world, you will need an API key. Since we are using the Google Static Map API service, you can get yourself a [Google API key](https://developers.google.com/maps/documentation/static-maps/get-api-key).
