Fractal Noise

Fractal noise with both the basis and the fractal shape chosen at runtime through pins. The most flexible noise node here and the least self-documenting.

Fractal Noise node

The Fractal Noise node

When to use it

Fractal noise with both the basis and the fractal shape chosen at runtime through pins. The most flexible noise node here and the least self-documenting.

Reach for it when a selector is genuinely driving the choice. Otherwise Simplex FBM, Perlin Ridged and the rest of the named nodes leave a graph someone can read.

Pins

Pin Type Description
Frequency Number How tight the biggest layer is. Everything else is built on top of it.
Lacunarity Number How much smaller each layer gets. At 2 every layer is half the size of the one before.
Gain Number How much quieter each layer gets. Low is crisp, high is rough and grubby.
OffsetX Number Slide the pattern along X.
OffsetY Number Slide the pattern along Y.
OffsetZ Number Slide the pattern along Z.
Seed Whole Number Change this for a different pattern at the same settings. The same seed always gives you the same noise.
Octaves Whole Number How many layers to stack. Past about 8 you are paying for detail finer than your voxels can show.
NoiseType Choice Which flavour of noise to use.
FractalType Choice How the layers get folded together: plain, ridged, puffy or churning.
Pin Type Description
Result Number The noise here. Roughly -1 to 1.
