Curved Track

One curve part for the kit's whole curve family: a radius knob of 8, 12, 16 or 20 m measured on the centre line and an angle knob of 22.5 or 45 degrees, so four 22.5-degree pieces or two 45-degree pieces turn a right angle and land back on the 4 m grid.

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
