Fractal Noise
Generates various fractal noises.
Fractal Noise
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
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.
Control the inheritance of the transforms from the parent.
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.
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.
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.
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.
Tiling Enabled Blends the sides of the texture together, Allowing it to tile without hard borders where the noise repeats.
Time Looping Enabled Allows the fractal animation to loop within a specified time range.
Time Loop Length The time span the fractal noise will loop within.
Animation Speed The speed at which the fractal noise is animated.
Time Offset Offset the current time the fractal noise updates within. Useful for manually controlling the speed of the fractal noise.
Num Octaves How many time the noise generation is iterated.
Invert Invert the brightness of the fractal noise, making the darker areas bright and the brighter areas dark.
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.
