Radial BlurAdd a blur effect which pushes outwards to an image.
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.
These properties control the core behaviours of the node.
|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.|
|Intensity||The intensity of the effect that is applied.|
|Blur Scale||How far the blur should push out. This is multiplied by the distance of the pixel from the center of the image.|
|Threshold||The luminance threshold at which a pixel will contribute to the effect.|
Toggle which of the RGBA channels are affected by the effect.
|Glow Mask Image||Use a mask image to control where the output is most or least affected by the effect, based on the mask images luminance.||Image Plane|
|Affected Objects||Change which objects are affects by the post effect. Deferred rendering must be enabled. By default, all objects are affected.||3D Object|
|Transform Controller||Set the origin/center point of the radial blur.||Null|
|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.||Envelope Modifier|
