Surface nodes
Add terraces, strata, contours, and small-scale surface character.

Surface
Contours
Draws elevation contour lines as a mask. A reference overlay for reading a heightfield, and a ready-made stripe pattern.
Surface
Fractal Terraces
Terracing at several scales at once, with the step heights jittered by noise so the shelves vary instead of marching evenly up the slope.
Surface
Roughen
Adds fine noise weighted by steepness, so exposed faces get broken up while flats and valley floors stay smooth.
Surface
Stratify
Cuts thin sedimentary bands across the terrain, strongest on steep faces where the layers would actually be exposed. What gives a large cliff its sense of scale.
Surface
Terraces
Quantizes height into steps. Sharpness controls how square the risers are — at 0 the steps are ramps, at 1 they are shelves.
