Grand Stair Flight (Between Levels)

A grand stair flight connecting two levels, with a landing. Fits 3m bay. Real-world scale at 3 x 3.18 x 4 m, 1,146 triangles on one material.

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
