Players' Tunnel

A real hole through a stand run on a 4x3m footprint, a 2.4m-wide arch-headed opening with a walk-through vault, painted block walls, a roller shutter that winds up on a real barrel and a cool-white lit mouth as its own zone behind a recessed frame.

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
