This operator produces a surface displacement that simulates small surface imperfections like those often seen in concrete walls.
The Displacement Scale (
scale) input determines the amount of overall
displacement of each frequency set. A positive scale will produce dents,
such as concrete holes and smallpox scars. A negative scale will
generate bumps, such as skin rash.
If the Position (
P) input and the Normal (
N) input are not connected,
the global variables by the same names will be used instead. Typically
you will use Rest Position or UV Space Change as inputs for
will not touch
N unless you want to apply additional displacement to
the stone 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.
