Adding a Directional blur node

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

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

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

Double click on the node to open its parameters:

Blurring the mask

• Intensity: Use the slider to define the intensity of the blur to apply, which is modulated by the control mask.
• 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 mask:
  • A value equal to 0.5 does not lead to any modification.
  • A value between 0.5 and 1 results in a blur in the direction defined by the chosen angle.
  • A value between 0 and 0.5 results in blurring 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 mask.
