Adding a Directional blur node

This node applies a blur on a terrain in a given direction.

The intensity of the blur is determined by a second terrain that causes the displacement on the terrain to modify. This terrain is called the control terrain.

To add a Directional blur node, right-click in the Graph Editor and select Create Node  > Terrain transformation  > Directional blur or use the keyboard shortcut NTDB for Node Terrain Directional Blur.

Double click on the node to open its parameters:

Blurring the terrain

• Intensity: Use the slider to define the intensity of the blur to apply, which is modulated by the control terrain.
• Angle: Use the slider to define the direction of the blur, between -180° and 180°. You can use the rotation manipulator to change the angle.
• For the control terrain:
  • A positive altitude results in a blur in the direction defined by the chosen angle.
  • A negative altitude results in a blur in the opposite direction.

The image below shows the result obtained for a directional blur of strong intensity with an angle of 45° on a terrain.
