Procedural Cobblestone Wall

Path-based HDA


Tool for drawing cobblestone walls. Can be used with curved or hard edge paths, with control over height, depth, and size of stones. Still working on a smart mask for the randomized colors; I can feed vertex colors to a substance baker for color variation, but that’s not a procedural solution for texturing.
