The functionality of the Height Tab in the Terrain Editor

Height Tab[]

The “Height” tab will allow you to change the topography and structure of your terrain in both the passable play area and in the border area that creates the bounds of your map.

To alter the terrain, select one of the brushes under the Brush Controls section and Left-Click the terrain. To reverse the direction of the brush, hold down the Control key and Ctrl+Left Click the terrain.

Tip: When using tools such as the surface noise brush which can rapidly change the terrain, be sure to repair or smooth out any visual tears in the terrain before saving and uploading your map.

Tip: If you wish to save a set of Copy Paste brushes for use in another session or map file, simply click the blue diskette icon to save the file. Similarly, if you wish to import a set of Copy Paste brushes, place the file in the same folder as your other Copy Paste Brush Files and then select that file from the drop-down list when in the terrain editor.

  • Under Brush Controls, select the brush type you would like to use.
    • Additive Brushes (Conical/Spherical) – These brushes will add or subtract height from the terrain in their respective shape.
    • Leveling Brush – This brush instantly sets the terrain to the height entered in the height field.
    • Ramp Brush – Ramps can be made from one area of terrain to another by clicking the start point of the ramp, clicking the end point of the ramp, then clicking one last time to confirm ramp creation.
    • Clamp Height Brush – Brush that pulls terrain toward a preferred height with adjustable intensity and variation.
    • Surface Noise Brush – Height adjustment brush which is able to paint variable patterns into the terrain.
    • Copy Paste Brush – Brush used to select an area of altered terrain and copy that terrain for placement onto other areas of the map. Copy Paste controls will be activated once a section of terrain has been selected for later use with the Copy Paste function.
    • Terrain Mask Brush – Brush used to paint a “mask” onto the terrain. Areas covered by a Terrain Mask are protected from alteration by tools which have that Terrain Mask selected.
  • There are various settings available under each brush control, some of which are only applicable for certain brush types:
    • Radius – Brush size.
    • Blend Radius – Size of area within the brush closest to the preferred height; areas between the blend radius and the brush radius will gradually change to the specified height.
    • Intensity – Rate/speed at which the brush alters the terrain.
    • Smoothing – Strength of the smoothing effect applied when the brush alters the terrain height.
    • Clamp Height – Height at which terrain will be adjusted towards.
