Concrete Skate Bump

Smooth mounded concrete obstacle for pumping and popping airs on flat ground: piece knob (low hump 2x2m and 0.3m tall, long whaleback 2x4m and 0.45m tall, volcano cone 4x4m and 0.9m tall with a flat cap, volcano with a steel-pipe lip ring round the cap).

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
