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.
