This operator simulates an anti-aliased stucco material, with its typical bumpy surface and light color.
The Displacement Scale (
scale) input determines the amount of overall
displacement of the frequency. A negative scale will turn stucco into a
dented material, somewhat akin to concrete.
will not touch
N unless you want to apply additional displacement to
the surface using an operator such as Bump Noise. If you need to access
the global variables directly, they are available from the Global Variables operator.
