start by adding the noise script to the project

evaluating the noise

multiply the point by a settings dot roughness

create the new noise filter

detailed bumpy surface and moving the center

increase the default value of roughness to 2

decrease the base roughness a little

define multiple noise settings and layer

toggle the visibility of a single noise layer

set up some mountainous terrain
