sci-fi greenhouse dome 3d model

Low-poly O2 Farm building for a Roblox space RTS tycoon. Squat octagonal gunmetal base, chunky beveled panels, pale metal trim, restrained cyan lights. Front airlock entrance in the METAL BASE below the dome, with a short ramp. Large transparent, lightly cyan-tinted hemispherical glass dome above. Inside: three cultivation beds of bright green seaweed with broad, simple ribbon leaves. Sparse sturdy metal ribs meet at a small circular top cap. Sealed floor separates aquatic dome from dry service base. Clean stylized sci-fi aesthetic, strong silhouette readable from an elevated RTS camera, simple geometry, minimal textures. Compact square foundation; ramp within footprint. Separate base, glass, ribs, beds, and seaweed objects if possible; separate materials. Single isolated building. No terrain, characters, text, logos, weapons, dense pipes, tiny details, weathering, or bubbles; bubbles will be animated in Roblox.
