industrial plant 3d model

Ultra-realistic 3D chemical refinery with a full concrete ground base (light grey #BEBEBE, stains, cracks), asphalt roads (dark grey #3A3A3A, white markings), and walking paths (#D0D0D0). Add strong contrast colors, detailed PBR materials, AO shadows, and realistic lighting. Include tall distillation towers, spherical steel tanks, large cylindrical storage tanks, horizontal vessels, heat exchangers, pipe racks, and a control building. Metal surfaces: brushed steel, metallic 0.9, roughness 0.35. Add trees on soil patches at edges. Ensure correct scale, clean topology, VR-ready, Unity-ready FBX/glTF, with albedo, normal, roughness, and metallic maps. No floating objects—everything grounded with shadows.
