Method
This effect blurs the bright parts of the image over the darker parts of the image, using a method that is resolution independent. Unlike the Glow node, Glow 2 is more resolution independent which means if the resolution is changed within your project the glow will still look the same.

Attributes
Name |
Description |
---|
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 Size |
Change the size of the blur based on the blur scale. |
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. |
Threshold Mode |
Select how the Threshold is calculated.
- RGB, The glow effect is done on the RGB values individually.
- Luminance, The glow effect is done on the Luminance values for all objects in the scene.
|
Apply to Opaque Objects Only |
Toggle whether the effect only applies to opaque objects. |
Wrap X |
Wrap the image on the left and right edges, so the glow overflows on each side. |
Warp Y |
Wrap the image on the top and bottom edges, so the glow overflows on each side. |
Affect Channels
Select which of the RGBA colour channels are affected by the effect.
