Fractal Sum Base

In: Generators/Noises

Simple

Description

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.

Parameters

• 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.
