Survey Drone

Small quad rotor survey drone, 1.1m across, off-white body with gunmetal rotor arms, four twin blade rotors, a cyan camera eye, resting on short landing skids.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
