SDF FBM node — Material Maker documentation

# SDF FBM node

The SDF FBM node adds layers of noise to a base 3D SDF shape.

## Inputs

The SDF FBM node accepts a single input in 3D signed distance function format.

## Outputs

The SDF FBM node generates a signed distance field of the base shape with the noise applied to it.

## Parameters

The SDF FBM node accepts the following parameters.

- The Mode of the operation, either additive of subtractive.

- The amount of Iterations performed.

- The Smoothness of the boolean operation performed at each iteration.

- A Scaling control to adjust how much the size of the noise is adjusted at each iteration.
