Voronoi Ridges
Creates a network of raised ridge lines along Voronoi cell boundaries. The surface looks like cracked earth, leather grain, giraffe spots, or biological tissue — the ridges mark the borders between randomly distributed cells.
Parameters
Depth- Ridge height in mm (0–20). Controls how far the ridges protrude along the surface normals.
Cells- Cell density around the circumference (2–20). More cells create a finer, denser ridge network.
Rows- Cell density along the height (1–20). Controls how many cell layers stack vertically.
Ridge Width- Width of the ridge lines relative to cell size (0–1). At 0, ridges are infinitely thin. At 1, ridges fill the entire space between cell centers.
Sharpness- Sharpens the ridge profile (0–1). At 0, ridges have a smooth falloff from peak to base. At 1, ridges have hard, cliff-like edges.
Seed- Random seed for cell positions (0–1000). Different seeds produce entirely different cell layouts.
How It Works
The effect distributes pseudo-random seed points in UV space based on the cell density. For each mesh vertex, it computes the distance to the nearest and second-nearest cell seeds. The difference between these two distances determines how close the vertex is to a cell boundary — vertices near boundaries (where two cells are almost equidistant) sit on ridges, while vertices deep inside a cell are unaffected.
The Ridge Width and Sharpness parameters control the falloff profile of this boundary distance function, allowing ridges to range from broad, soft hills to thin, sharp walls.
