Anisotropic Noise
Anisotropic Noise
Anisotropic Noise creates an elongated random-value field. X Amount and Y Amount set the number of regions on each axis; the default makes horizontal strips. Rotate turns the field 90 degrees. Smoothness sets how much of each region fades into the next, while Smoothness Interpolation blends a linear fade toward a smoother quintic curve. Disorder and Disorder Speed bend the bands. A seed makes the pattern reproducible. Goblin Node also supports independent tiling axes, non-square expansion, and multichannel RGB output.
Availability
This node requires Pro.
Common uses
- Start with X Amount 1 and Y Amount 18 for horizontal bands; turn on Rotate for vertical bands.
- Increase X Amount to break the strips into shorter segments.
- Use Smoothness 0 for sharp boundaries or 1 for fades spanning each region.
- Enable Multichannel for independently seeded red, green, and blue fields.
Input ports
-
None
-
No image input is required; graph and node seeds control the generated field.
Output ports
-
out -
Outputs grayscale by default or independent RGB channels when Multichannel is enabled.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| X Amount | int | 1 | 1 to 128 |
| Y Amount | int | 18 | 1 to 128 |
| Y Amount by Resolution | bool | false | - |
| Rotate 90° | bool | false | - |
| Smoothness | float | 0.75 | 0 to 1 |
| Smoothness Interpolation | float | 0.5 | 0 to 1 |
| Disorder | float | 0 | 0 to 1 |
| Disorder Speed | float | 0.5 | 0 to 2 |
| Seed | int | 12345 | 0 to 65535 |
| Non-Square Expansion | bool | false | - |
| Multichannel | bool | false | - |
Behavior
- Values are deterministic for a given graph seed, node seed, and parameters.
- When tiling is enabled, the field and displacement repeat across the selected edges.
- Non-Square Expansion keeps regions closer to square on rectangular images; Y Amount by Resolution adjusts Y count only when expansion is off.
Common mistakes
- A single region on a tiled axis is constant along that axis; increase its amount to add variation.
- Very high counts at a small output resolution can alias.
- Disorder Speed scales the displacement amplitude, not animation time.
