Frozen Waterfall

Frozen waterfall, 4 m, free-standing on its own flat base at y=0 so it drops down a terrain step without any cliff part: a rounded stepped column of milky and clear ice over a bulged apron, with an icicle fringe at the lip and a frozen pool skirt at the foot.

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
