This mode is used to give further detail to the terrain in the form of undergrowth. With this mode you will be able to create undergrowth materials and place undergrowth areas.

Undergrowth Fading parameters: will define the range where the undergrowth will be visible.

Undergrowth material editor button: pressing this button will open the Undegrowth material editor window. In it the user will find the needed parameters to set up a proper undergrowth material, to be used later by undergrowth areas.

The following parameters control several aspects of the creation of undergrowth areas:

• Material: the undergrowth material that will be used by the next undergrowth area that will be created.
• Blend type: this setting will determine if the next created area will either add or substract undergrowth.
• Area type: use this setting to select the type of the next created area out of the two available types:
  • Circle: To place a circle, just click and hold the left mouse button on the desired spot on the terrain to define the center, then drag over the terrain to define the radius of your circle area. The creation will be done as soon as you release the left mouse button.
  • Polygon: polygon areas are created on the terrain by placing vertices. To place a vertex, just click and release anywhere on the terrain. Polygons must be convex, so further vertex placement will be constrained to the validity of the resulting polygon. To remove the last placed vertex, click the right mouse button. To finish creating a polygon, double click or click on the first vertex.
