Ambulance Van

Boxy front-line ambulance about 6m long on the kit scale, high box body over a van cab, light bar, battenburg side stripe, rear step and a rear-door open/closed knob, plus a livery colour knob.

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
