To see the terrain below your aircraft, you have to install the respective [[scenery]].

Alternatively you can use '''TerraSync'''. It is a utility that automatically downloads the newest version of the needed [[FlightGear]] [[scenery]] while the simulator is running.

The master repository for terrasync, i.e. the online resource from which TerraSync downloads its files, is synchronized with the [http://scenemodels.flightgear.org/ FlightGear Scenery Database] once a day.

So when using TerraSync, you will always have 1) the latest [[File Formats#.2A.stg|.stg-files]], which tell FlightGear where to place an object and 2) the latest '''static''' models for objects. (Static models define unique objects that exist in one place only, such as famous buildings or landmarks.) | ||
As of March 2011, TerraSync also downloads '''shared''' models, at least when it first runs. (Shared models are generic models used more than once in different places, each can represent many different objects, like generic houses or ships.) It does not, however, install the shared models, and until they are installed in the right place, you won't see any objects that are based on them. You will need to copy all the files from the Models directory inside your TerraSync directory to <code>[[$FG_ROOT]]/Models</code>, replacing the files that are already there. (If for some reason you suspect your models are not up-to-date, you can also manually download the newest [http://scenemodels.flightgear.org/download/SharedModels.tgz '''shared''' models archive] from the [http://scenemodels.flightgear.org/ FlightGear Scenery Database]. Unpack it to <code>$FG_ROOT/Models</code>. See also: [[Howto: Animated jetways#Usage]].) | |||

If/when that happens the easiest solution is to delete the affected subdirectory and let terrasync download it again. | ||
