60 m x 30 m x 26 m crystalline alien vessel: straight-faceted crystal shard bouquet, branching magma/cyan energy veins, rotating Core, flat-bevelled dark metallic cradle arcs, 4 stepped stabilizer pods, and rear engine ring.
64,508 triangles across 2 mesh nodes (Hull, Core) and 11 contractual empty sockets; 7.65 MiB GLB (Y up, +Z nose, origin at centre of mass).
Six baked PBR materials: Paint (neutral crystal facet/cleavage texture x [0.12, 0.30, 0.45] sea-glass blue factor + iridescence), DarkMetal, BareMetal, ScorchedMetal, Engines, and Lamps.
Game-weight textures: Paint 1024x1024 Base+Normal / 512x512 ORM; DarkMetal 1024x1024 Base / 512x512 Normal+ORM; BareMetal/ScorchedMetal 512x512; Engines/Lamps 512x512 Base / 256x256 Normal+ORM.
CC0 Poly Haven texture IDs used: marble_rock_01, blue_metal_plate, metal_plate_02, rusty_metal_02 (diff, nor_gl, arm 1k maps).
Differences from reference: removed small numerical hull stencil on rear engineering panel per no-text contract; inner core chamber channels opened slightly so the spinning Core reads clearly.
