silhouette-2024.5 : Nodes : Fractal Noise
Fractal Noise
Description
Fractal Noise is a noise texture based on Perlin noise.
Node Group
Image.
Controls
Format
Sets the output resolution.
Custom
Set a custom output resolution.
DOD
The DOD parameters appear when Custom is selected. Go to the DOD section of the Common Node Controls to see how they work.
Default
The resolution is set to whatever the node indicates its DOD is, which is usually infinite.
Session
The session size is used for the output resolution.
Scale
Scales the noise.
X Bias
Moves the noise horizontally.
Y Bias
Moves the noise vertically.
Lancunarity
Lacunarity defines the gap between the various frequencies that are added together to form the texture. Higher Lacunarity values increase the complexity and detail in the texture. Lower values make the texture smoother with less detail.
Increment
Increment controls the ratio of noise in the texture. Higher values blend the light and dark areas together. Lower values create a more contrasty texture.
Octaves
Octaves controls the number of texture calculation iterations. Fractal textures work by running an algorithm iteratively. The longer it runs, the more detail it creates, but the slower it goes. Increase Octaves to make the texture more detailed. This is good to do if it will be seen up close in the final rendered image.
Amplitude
Scales the final result.
