This was a fun project that helped me study up on ways to make various rock shapes using 100% Substance Designer.
I didn't show them all here, but the final output is a combination of a few different graphs:
-A graph creating the basic rock and pebble shapes (height only)
-A graph combining the rock shapes together into a definitive design (height, normal, and curvature)
-And a graph where I created the dirt (shown here)
