The type of terrain rendered by the map can be modified with the MapTerrainType.
Default: The map terrain consists of either elevation data or high resolution 3D models.
Elevated: The map terrain consists only of elevation data. No high resolution 3D models are used.
Flat: Both elevation and high resolution 3D models are disabled. The map terrain surface will be flat.
Map terrain types: default, elevated and flat.
If the scenario does not require the higher resolution data, disabling the terrain can improve performance. Likewise, the Flat type requires the least amount of performance overhead.
