Feedback Blur

Feedback Blur

Add a blur which trails across the image to an image.


Method #

This node combines a few different blurring effects to create a trailing blur from a line across the image.


These properties control the core behaviours of the node.

ActiveEnables 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 AmountChanges 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.
Previous Frame FeedbackHow much the previous frame effects the current frame.
RotationEdit the rotation of the effect.
Stretch PositionChange the position of the stretch.
Stretch FalloffChange the falloff length of the stretch.
Blur ScaleHow far the blur should push out. This is multiplied by the distance of the pixel from the center of the image.

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