Adding a Transform terrain node

This node modifies the first terrain before it is inserted into a second terrain.

This node is quite similar to the Full composition node, except that its role is to modify a terrain and not to compose it with another one. Like the Full composition node, this node also has multiplying coefficients: one to manage the height of the input terrain and another to manage the area outside the terrain after rescaling the terrain or increasing the terrain size.

To add a Transform terrain node, right-click in the Graph Editor and select Create Node  > Terrain Transformation  > Transform terrain.

Double click on the node to open its parameters:

Editing a Transform terrain node

Edit the Transform terrain node in the parameters dialog:

• Terrain size: Sets the Width, Height, and Quad size of the terrain.

• Coefficient for the input terrain: Sets the coefficient by which the height of the input terrain is multiplied.

• Height outside of the input: Sets the height of the output terrain vertices around the input terrain if the output terrain is larger than the input terrain.

• Color outside input: When the input terrain is linked to a color map, this parameter is displayed; otherwise, it is hidden.

• Translation X and Y: Translates the input terrain along the X and Y axis. The translation values are relative to the output terrain size:

• Scale X and Y: Scales the input terrain along the X and Y axis.
  Check Keep aspect ratio to scale along the X or Y scale preserve the relative horizontal and vertical sizes.Note that when the scale manipulator is displayed, it is no longer possible to select a single axis; both axes are selected at the same time.

 

• Rotation: Rotates the input terrain around its center from 0 to 180 degrees.
