Noise

Updated: 24 Feb 2025

Add random noise to the image.

Method #

This node overlays random noise on to the image, useful for quickly adding low level noise to an image or larger stylised blocks of noise.

Attributes

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.
Amount	How strong an effect will be applied to the image.
Scale	Scale the size of the generated fractal noise.
Animation Rate	The speed at which the fractal noise is animated.
Attack	How quickly a random point reaches its peak.
Decay	How quickly a random point decays.
RGB Noise	Toggle whether the noise is randomised colour, or randomised black and white..
Mode	Choose different kinds of noise. Point : The noise generates random points of differing brightness for each frame. Lines : The noise generates parallel lines of differing brightness. Time Filtered Points : The noise is generated through random points at random times, allowing for the noise to be animated smoothly.
Interpolation	Toggle whether noise is interpolated between frames.

Affect Channels

Toggle which of the RGBA channels are affected by the effect.
