Fractal Noise generates a greyscale noise pattern from several octaves of detail and blends it with the layer.
Parameters
| Name | What it does | Default / range |
|---|---|---|
| Fractal Type | Basic, Soft, Turbulent, Rocky, or Chunky (blocky texture). | Basic |
| Scale | Pattern size in pixels. | 100, 1–2000 |
| Complexity | Number of noise octaves (layers of detail). | 6, 1–10 |
| Contrast | Pattern contrast. | 1, 0–4 |
| Brightness | Pattern brightness. | 0, −1–1 |
| Invert | Inverts the generated pattern. | Off |
| Position X | Pans the pattern horizontally, layer pixels. | 0 |
| Position Y | Pans the pattern vertically, layer pixels. | 0 |
| Evolution | Animate to morph the texture in place. | 0, −100–100 |
| Loop Evolution | Makes the evolution cycle seamlessly. | Off |
| Revolutions | Evolution units per seamless loop. Animate Evolution from 0 to this for one cycle. | 4, 0.5–50 |
| Random Seed | Picks a different random pattern. | 0, 0–1000 |
| Blend Mode | How the pattern combines with the layer: Normal, Add, Multiply, Screen, Overlay, Difference, Soft Light. | Normal |
| Blend With Original | 0 = full effect, 1 = reveal the layer below. | 0, 0–1 |
Tips
- For a seamless loop, turn on Loop Evolution and keyframe Evolution from 0 to the Revolutions value over the loop length.
- Put it on a solid to make a texture layer, then use that as a matte or displacement source.
