Underground hydroelectric power cavern

Generated from: Third-person over-the-shoulder game camera view deep inside a colossal underground hydroelectric facility carved from dark rock, enormous spinning turbine rotors visible behind reinforced glass walls lining the main corridor, rushing water visible through grated floor sections and through a lower flooded tunnel branch, the playable ground is a wide industrial walkway with metal railings and junction doors, mission objective glowing at a massive control panel at the far end of the hall, emergency amber lighting and electric-blue turbine glow competing in the colour palette, water mist in the air, enterable side rooms with equipment crates, dramatic low-angle perspective showing the enormous scale, photorealistic-inspired 3D render with hard-surface materials Drawn in this game's art direction: Cinematic photorealistic-inspired hard-surface 3D render; physically based rendering with brushed metal, tempered glass, carbon fibre and reinforced concrete materials; dramatic directional lighting with volumetric rays, rain wetness, and sea mist atmosphere; palette of midnight blue, electric blue, charcoal black, amber warnings, white energy highlights and renewable-green accents; third-person over-the-shoulder camera feel with controlled depth of field; futuristic but grounded and believable scale Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one: take a named game's look and mood, never its characters, names or logos. No text, UI, HUD, logos or editor screens inside any image.
