Snowfall in a Futuristic Robot Factory (3D Render)

Ultra-detailed 3D render of a vast futuristic robot factory interior during a snowfall. Snowflakes drift through skylights and large vents, settling on chrome arms, polished steel floors, and frost forming on glass panels. The factory features towering robotic arms, assembly lines, conveyor belts, crates, drones buzzing, pistons, and hydraulic pipes. Cold blue and cyan rim lighting mix with warm amber interior lights to create strong color contrast. Surface detail includes brushed aluminum, tiny rust specks, oil slicks, and scratches. The camera is at a slightly low angle, looking down a long aisle receding into depth, with depth of field and subtle motion blur on distant machinery. Use volumetric lighting to show snow volumes, soft shadows, and realistic reflections on wet floors. Render in photorealistic 3D with physically-based rendering, high dynamic range, and crisp detail. Mood: serene yet industrious, wintery atmosphere.
