Fractal Noise

Generates various fractal noises.

Method #

This node generates fractal noise patterns based on various properties, with multiple noise pattern options available.

This node can be connected to any node which accepts an image input.

Parameters

Transform

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Parameter	Details
Position X	Move along the local x-axis.
Position Y	Move along the local y-axis.
Position Z	Move along the local z-axis.
Rotation Heading	Rotate around the local y-axis.
Rotation Pitch	Rotate around the local x-axis.
Rotation Bank	Rotate around the local z-axis.
Scale X	Scale along the local x-axis.
Scale Y	Scale along the local y-axis.
Scale Z	Scale along the local z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

Parameter	Details
Position X	Toggle inheritance of the X Position from the parent.
Position Y	Toggle inheritance of the Y Position from the parent.
Position Z	Toggle inheritance of the Z Position from the parent.
Rotation Heading	Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch	Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank	Toggle inheritance of the Rotation Bank from the parent.
Scale X	Toggle inheritance of the X Scale from the parent.
Scale Y	Toggle inheritance of the Y Scale from the parent.
Scale Z	Toggle inheritance of the Z Scale from the parent.
World Position Only	Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time	Toggle inheritance of time from the parent.

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.
Preview In Viewport	Preview the effect blended with alpha in the viewport.
Preview RGB In Viewport	Preview the colour values in the viewport.
Preview Alpha In Viewport	Preview the alpha values in the viewport.
Width	The resolution of the effect along its width.
Height	The resolution of the effect along its height.
Update Time Mode	How the generator updates with relation to the timecode. Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result. Running / Loopable : The generator animations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Static Image (Process Only Once)	Only process the image once, making a more efficient scene. Animated Post-FX nodes will not function with this enabled.
Noise Type	Select the noise function to generate noise from. FBM : Generates cloudy noise using a Fractal Brownian Motion algorithm. Turbulence : Generates bumpy noise using a turbulence noise algorithm. Ridged : Generates curvy looking noise from an inverse of the turbulence noise algorithm. Marble : Uses FBM noise to displce a sine wave pattern, creating a marbled pattern. Ridged 2 : Generates curvy noise similar to Ridged mode, but with thinner lines and a stronger falloff curve. Simplex FBM : Generates a smoother cloud noise using the simplex noise alorithm. Worley F1 : Generates cellular noise using the F1 variant of the worley algorithm. Worley F2-F1 : Generates a patterned noise noise using the F2 variant of the worley algorithm subtracted from the F1. Worley F2+F1 : Generates a layered cellular noise by adding the F1 and F2 variants together. Flow : Generates a liquidy noise by stretching and sqaushing different parts of an FBM generated noise. Warped 1 : Generates an oily noise by randomly displacing a simmpler noise pattern at a low octave value. Warped 2 : Generates an oily noise by randomly displacing warped noises at a medium octave. Warped 3 : Generates an oily noise by randomly displacing warped noises at a high octave. Warped Rotate 1 : Generates an oily noise by randomly stretching and scaling a simpler noise pattern.
Amount	Change how strong the brightness of the fractal noise is.
Noise Threshold	Minimum value threshold for where the noise will be generated.
Noise Scale	Scale the size of the generated fractal noise.
Lacunarity	How large the gaps between larger areas of noise are.
Gain	The overall smoothness of the generated fractal noise.
Animation Speed	The speed at which the fractal noise is animated.
Num Octaves	How many time the noise generation is iterated.

Rendering

These properties control how the generators are coloured and blended with other images.

Parameter	Details
Colour	Change the colour of the generated image.
Blend Amount	The amount the generator is blended with the output.
Blend Mode	Choose how the image blends with the scene. See Blend Modes for details. Solid : The generator is solid, with a filled alpha channel. Blend : The generator RGBA values have matching alpha channels. Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
