ZBrush Dinosaur Horn and Plate Modeling Techniques

Horns and osteoderms are among the most striking features of many dinosaurs. This tutorial breaks down modeling techniques for various bony protrusions in ZBrush. Triceratops' brow and nasal horns are solid bone structures: use the Snake Hook brush to pull out the basic form from the skull surface, then build volume with Clay Buildup. Horn growth textures typically feature spiral or longitudinal striations; apply a Custom Alpha along the growth direction to stamp regular surface patterns. Horn tips are usually smoother than the base and show signs of wear. Ankylosaurus scutes are flat bone plates embedded in the skin: insert the mesh using Insert Mesh, flatten it with Flatten to conform to the body surface, and blend the edges smoothly into the skin. Stegosaurus plates are unique, potentially containing internal vascular channels and covered externally by a rough keratin layer. Model the inner bony core first, then wrap it with an outer keratin sheath, leaving a tiny gap between layers to suggest biological structure. Plate arrangements follow bilateral symmetry but include slight natural variations; perfect symmetry can look artificial. Aging effects such as edge wear, cracks, and moss attachment can be achieved by layering different sculpting passes. For animation projects, keep horns and osteoderms as separate SubTools for independent control and collision detection.
