Fractal Sum Base
This generates a fractal noise with strong small-scale, pixel-level details and subtle higher frequency variation, plus lots of control to modify behaviour. It is similar to Clouds or BnW Spots, but more uniform and with less well-defined patterns in most cases.
A very useful node due to this subtle nature, ideal for blending in some subtle, pixel-level details. Additionally, its parameters make this node one of the most powerful and customisable noises available.
- Roughness: 0.0 - 2.0
Changes balance between large- and small-scale detail.
- Global Opacity: 0.0 - 2.0
Works like a global brightness control.
- Min Level: 1 - 12
Changes lower frequency for detail.
- Max Level: 1 - 12
Changes upper frequency for detail.
- Non Square Expansion: False/True
Enables compensation of squash and stretch with non-square ratios.
