Ant Tunnel Run

Ant tunnel run, the modular underground nest set: packed-earth tunnel pieces on a 4m grid, every mouth the same arched bore (2.4m wide, 2.2m tall, flat floor at 0, walls 0.5m thick) dead flat on the module edge, so any piece butts any other.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
