Stone Cairn

Stone cairn, 1.4 m: a tapered pile of flat mountain stones laid course on course with a bigger capstone and a wedged marker slab on top, flat on y=0; a person built it, which is why it is a part and not terrain.

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
