Voronoi Cells
Creates a faceted, crystalline surface texture using a Voronoi cell distance field. Each cell gets a displacement based on its distance from the cell center, producing a mosaic of concave or convex facets — like a cracked gemstone, dried mud, or a honeycomb with varying depth.
Parameters
Amplitude- Depth of the cell pattern in mm (0–20). Controls the maximum height difference between cell centers and cell boundaries.
Cell Count- Approximate number of Voronoi cells on the surface (1–30). Higher values produce more, smaller cells.
Seed- Random seed for cell positions (0–1000). Different seeds produce different random cell layouts.
How It Works
Voronoi Cells scatters random seed points across the UV surface and assigns each mesh vertex to its nearest seed. The displacement at each vertex is based on the distance to that nearest seed — vertices close to a seed center sit at maximum displacement, while vertices far from any seed (near cell boundaries) sit lower.
This creates a patchwork of convex facets, each one highest at its center and sloping down toward its neighbors. The randomness of the seed placement ensures that cells vary naturally in size and shape.
Unlike Voronoi Ridges (which displace at the boundaries), Voronoi Cells displace within the cells themselves — the two effects are complementary.
