Diamond Crossing

Flat crossing of two tracks with an angle knob of 22.5, 45 or 90 degrees: the first road on x = 0 from z = 0 to z = 8, the second road crossing it through the same mid-point.

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
