RGB Distortion
Updated: 24 Feb 2025
Add RGB sine distortion to an image.
RGB Distortion
Method #
This node applies multiple sine waves to distort the image, each corresponding to an RGB channel. The result is then further distorted with noise, to get a convincing distortion effect. Useful as a part of a digital glitch effect, simulating the RGB channels misaligning in a CRT display.
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.
Amount
How strong an effect will be applied to the image.
Red Distribution
Distribution of red distortion.
Green Distribution
Distribution of green distortion.
Blue Distribution
Distribution of blue distortion.
Distort Y
Distortion on the y-axis.
Sine Scale
Scale of the sine wave.
Noise Scale
Scale of the noise.
Speed
Speed at which the distortion is animated.
Toggle which of the RGBA channels are affected by the effect.
Inputs
These properties control the core behaviours of the node.
