Underwater Research Habitat

Submerged research habitat with an exact 8x8m footprint of two by two grid modules and flat vertical side walls on the footprint edges so copies butt into a station, a chunky riveted pressure hull with a big round viewport on the front face.

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
