Video game spacecraft design turnaround plate, photorealistic CG concept art, on a plain light grey background. A realistic, believable alien flying saucer (classic disc, our own design): a wide double-convex metal disc with a raised central dome, an outer rim with a ring of recessed light ports and a rotating outer ring, a belly emitter lens, three landing legs retracted into flush pods, seamless panel lines, subtle iridescent metal. Original design, not from any film, series, anime or game. No logos, no insignia, no flags, no text markings, no numbers on the craft. Real size 28 m diameter, 8.5 m high. Layout: big orthographic side view across the top, front view, rear view and top view below, and a 3/4 front hero view; callouts naming the main parts and dimensions in metres; material swatches (hull paint, bare metal, heat-scorched metal, glass, engine glow). Rich believable construction detail: panel lines, hatches, thrusters, vents, light wear. No other text.
