Deep-space exploration and science vessel: 160m x 70m x 70m hard-sci-fi spacecraft with forward observation dome, open-truss spine, rotating habitat ring, solar/radiator arrays, dorsal dish antenna, sensor booms, and rear magnetic fusion drive.
76,272 triangles; GLB size 6.32 MB; Y-up (+Z nose, +Y up, +X port/left), origin at hull centre of mass (0,0,0).
8 materials: Paint (neutral detail texture x linear baseColorFactor), Metal, Scorched, Solar, Interior, Glass (alpha BLEND), Engines (emissive), Lamps (emissive).
Texture sizes: Paint & Solar basecolor 1024x1024, normal/ORM <=1024/512; Metal/Scorched/Engines 512x512; Interior/Lamps/Glass 256x256.
Poly Haven CC0 ids: metal_plate_02, metal_plate, painted_metal_shutter, blue_metal_plate, rusty_metal_03 (diff, nor_gl, arm 1k maps).
Reference differences: added full 3D bridge interior behind the observation dome, point-defense/sensor turrets per spacecraft contract, and lateral telemetry booms spanning the 70m width.
