Seed: seed of the 4d voronoi

Threshold: how much of the surface is rust

Transition Band: the small band where the rust and the base material mix

Darkening: how much the darkening map affects the color

Darkening band: the band where the rust goes from fully bright to a darker shade towards the center of the clumps
