Glow 2
Updated: 13 Feb 2025
Add a glow effect which stays resolution independent to an image.
Glow 2
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.
Parameters
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.
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.
Glow Difference As Alpha
Use the generated glow effect to also apply glow to the existing alpha channel.
Apply to Opaque Objects Only
Toggle whether the effect only applies to opaque objects, useful for limiting effects to certain objects. Not compatible with alpha blended objects.
Wrap X
Wrap the image on the left and right edges, so the glow overflows on each side.
Wrap Y
Wrap the image on the top and bottom edges, so the glow overflows on each side.
Toggle which of the RGBA channels are affected by the effect.
Inputs

| Name | Description | Typical 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 |
| Effect Image Amount | Changes how much the Effect affects the image, based on an input image. | Video Loader |
| Glow Size Image | Changes the size of the glow for different parts of the image, based on an input image. | Video Loader |
| Affected Objects | Change which objects are affects by the post effect. By default, all objects are affected. | 3D Object |
