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.

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.
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.

Affect Channels

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