Directional Blur

Add a blur effect along a direction to an image.

Method #

This node blurs the image in a direction by taking multiple samples of the image and stacking them based on the blur direction and blur amount.

A simple trick to smooth out the samples is to use two direction blurs, one with a low blur amount, and the other higher.

Attributes

These properties control the core behaviours of the node.

Parameter	Details
Active	Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount	Changes the opacity of the new effect over the original image.
Blend Mode (RGB)	Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha)	Change how the generated effect blends with the parent image alpha.
Blur Length	How far the image is blurred.
Angle	Edit the rotation of the effect.

Affect Channels

Toggle which of the RGBA channels are affected by the effect.

Name	Description	Typical Input

Angle Image	Use an image to control the angle the image is blurred in.	Image Plane
