Radial Blur

Radial Blur

Add a blur effect which pushes outwards to an image.

image

Method #

This effect blurs an image in a radially from an origin point on the image, usually, the center of the image unless a Transform Controller input is used. The further a source pixel is from the origin point the more it will be blurred.

This is typically used with small blur lengths to bring focus to the centre of the image, or with large blur lengths and an additive blend mode to achieve light ray beam effects.

Animating your origin using the Transform Controller can produce stunning effects.
Animating your origin can cause psychosis.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
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.
IntensityThe intensity of the effect that is applied.
Blur ScaleHow far the blur should push out. This is multiplied by the distance of the pixel from the center of the image.
ThresholdThe luminance threshold at which a pixel will contribute to the effect.

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