Export Terrain Block

Exports a section of the terrain as a terrain block (.trb) file. 

First enable the terrain selection mode with the Select Terrain Area button.

Finally select the Export Terrain Block function or the save terrain block as geometry. 

Import Terrain Block

Imports terrain from a previously saved terrain block file. 

Save Terrain Block as Geometry

Using this function you can save a part of the terrain as an .obj file that can be modified in a 3D graphics application. Have a look in the Export Terrain Block description how to export a section of the terrain. 

Resize Terrain

Opens the terrain resize window where you can change the heightmap of the level by modifying the Highmap Resolution setting and Meters Per Unit setting. 

Meters Per Unit represents the distance between two verticals (lying on a perpendicular grid) in meters. Adjusting the Meters Per Unit will change the size of the heightmap. Changing the Meters Per Unit to 1 will make the terrain more detailed and changing to a higher value will make the terrain less detailed allowing you to create a bigger level with the same base heightmap resolution. The default setting of 2 means that the distance between two vertices every 2 meters there is a new point: 

When using this option only the terrain is changed, objects and vegetation must either be deleted or moved to the new location.
