220 spheres dropped from height into a constrained space. Three materials: red ring stripe on dark glass, gunmetal chrome, black-and-white vertical stripe. All procedural — no external textures.
Instanced rendering across three InstancedMesh objects. XZ-only repulsion physics run over 20 iterations per reset to resolve overlaps before the drop, keeping all marbles at floor level and all three types visible.
Gravity at −22 m/s², absorptive bounce dampening at 0.35, angular velocity assigned on first impact. Click to reset and drop again.
