Cowled chimney stack

Tall salvage chimney stack about 4m, a riveted plate flue widening at the base with brass strap bands and a spinning verdigris cowl on top, a small guy wire lug and moss at the foot, sits on a flat pad or roof, cowl as an animatable group.

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
