Method
This effect blurs a texture in a radial directional fashion 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.

Attributes
| Name | Description |
|---|---|
| Active | Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. |
| 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.. |
Affect Channels
Select which of the RGBA colour channels are affected by the effect.
Inputs
| Name | Description | Typical Node Input |
|---|---|---|
| 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 effect. by default, all objects are affected. | 3D Object |
| Transform Controller | Set the origin/center point of the radial blur. | Null |
| Active | Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. | Envelope Modifier |
