A single, reusable die component for a dice roguelike, rendered in real time inside Rive — no game engine. The cube is procedural rounded geometry; its marble surface was baked in Blender and cel-shaded through a custom WGSL shader. Each face's numeral and hero symbol are composited into a texture atlas and engraved into the stone as a lit height-field, so the carving reacts to light as the die spins.
