Obelisk in a Gears Factory - 3D Render

3D render of a colossal obelisk standing in the middle of a bustling gear factory. The obelisk is tall and slender, made of brushed steel with subtle etched glyphs along its length, cool blue reflections, and a slightly weathered patina. The factory floor is dense with massive cogwheels, interlocking gears, conveyor belts, oil slicks, and overhead cranes. Lighting is dramatic and industrial: harsh white overhead fluorescents, dust motes glowing in light shafts, and warm furnace glows in the distance. The perspective is a low-angle shot from near the floor, looking up to emphasize height and scale; depth of field keeps the obelisk sharp while foreground machinery recedes into a soft blur. Materials: metal textures with chipped paint, riveted joints, grime, wet slicks on concrete. Atmosphere: smoky haze, steam vents, occasional sparks from a lathe. Additional touches: tiny drones or robotic arms tending to machines in the background; reflections on polished surfaces and a mirrored sheen on the obelisk. Style: ultra-realistic, photorealistic 3D render, physically based rendering, 4K, with strong ray-traced shadows and subtle cinematic grain.
