Set of Points

One turnout part with a hand knob (left or right) and a blades knob (range 0 to 1) that throws the tapered switch blades and tie bar from the straight road to the diverging road; the straight road runs 8 m along x = 0 from z = 0.

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
