Adding a terrain Full composition node

This node gives maximum freedom to compose two terrains. The second terrain can be translated in the X and Y axes, scaled, and rotated before composing it with the first terrain.

To add a node, right click in the Graph Editor and select Create Node  > Terrain Composition  > Full composition.

Double click on the node to open its parameters:

The gizmo appears in the 3D View:

Editing a terrain Full composition node

Edit the Full composition node in the parameters dialog:

  • Coefficient for the first terrain: Sets the coefficient by which the height of the first input terrain is multiplied.
  • Coefficient for the second terrain: Sets the coefficient by which the height of the second input terrain is multiplied.
  • Translation: Sets the translation along the X or Y axis applied to the second input terrain before composing it with the first terrain.

Use the gizmo to set the translation values by clicking and dragging either the center, the X axis, and the Y axis of the gizmo:

The translation values are relative to the size of the output terrain. A value of 0 positions the center of the second input terrain at the center of the output terrain.
An X value of -1 positions the center of the second terrain on the left edge of the output terrain.
A Y value of 1 positions the center of the second terrain on the right edge of the output terrain.

  • Scale: Sets the X axis or Y axis scale to be applied to the second input terrain before composing it with the first terrain.

The default scale value is 1, which means that the second input terrain retains its default size. This is not the case for the Terrain composition node where the second input terrain is automatically scaled so that its size corresponds to that of the output terrain.

  • Rotation: Sets the angle in degrees to rotate the second input terrain around its center before composing it with the first terrain.
