Updated: 22 Sep 2025
Add a blur which trails from a line across the image.
Feedback Blur
Method #
This node combines a few different blurring effects to create a trailing blur from a line across the image.
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.
Previous Frame Feedback
How much the previous frame effects the current frame.
Rotation
Edit the rotation of the effect.
Stretch Position
Change the position of the stretch.
Stretch Falloff
Change the falloff length of the stretch.
Blur Scale
How far the blur should push out. This is multiplied by the distance of the pixel from the center of the image.
Inputs
