scrap sorting conveyor 3d model

Create a 3D model of an industrial scrap sorting system section, including the input feed stage and straight conveyor system. The input feed stage has a large rectangular hopper with adjustable metal gate, steel support beams, and optional rubber lining inside. The conveyor system is 12 meters long and 3 meters wide, composed of modular straight segments with a continuous rubber belt (no visible rollers), metallic frame, side rails, and motor/drive housing. Include optional cable trays, sensors, and overhead camera mounts. The model should be low-poly, game-ready, optimized for real-time web use, with PBR textures (metal, rubber, painted steel). Ensure modular design so hopper and conveyor can be duplicated or extended. Export in FBX or GLB format.
