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.

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 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.
