Directional Blur
Updated: 13 Feb 2025
Add a blur effect along a direction to an image.
Directional Blur
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.
Parameters
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.
Affected Channels
Toggle which of the RGBA channels are affected by the effect.
Blur Length
How far the image is blurred.
Angle
Edit the rotation of the effect.
Inputs
These properties control the core behaviours of the node.
