# Fractal Noise Procedural

The **Fractal ****Noise** texture node generates a fractal-based pattern (figure 1).

## Fractal Noise Parameters

**Mode** - Specifies whether scalar or vector mode is used to calculate the fractal noise.

**Colors 1 & 2** - Specifies the two colors used to generate the fractal noise.

**Time** - Shifts the fractal pattern over time.

**Octaves** - Specifies the multiple frequencies in which the fractal pattern is repeated.

**Distortion** - Determines the scale of random displacement applied to the fractal pattern.

**Lacunarity** - Controls the size of the space in the fractal texture pattern.

**Gain** - An amplitude multiplier per iteration where higher values will result in a flatter pattern.

**Turbulent** - Adds an additional layer of noise to the fractal pattern.

**Transform** Input - Positions, scales, and rotates the surface texture.

**Projection** Input - Sets how the texture projects onto the surface.
