“A compact underwater equipment locker designed for a submersible base interior. The locker is rectangular with rounded corners, finished in teal-blue metal panels and lighter trim. The front opens into visible compartments holding simplified diving gear, helmets, and storage cylinders. Bold shapes and clear divisions avoid small details while suggesting functional depth. Light scuffs and faded markings add realism. The locker is perfectly centered against a pure white background, softly illuminated with neutral studio light, minimal shadow. Ultra-realistic PBR materials with painted metal surfaces and restrained wear.”
