open pit mine 3d model

Create a detailed **3D terrain model of an open-pit mining site** designed to appear **large-scale and visually continuous so it can fill an entire laptop screen without visible boundaries**. The environment should represent a realistic quarry landscape with multiple **terraced excavation levels descending toward the center**, showing clear geological layers and rugged rock faces. The terrain should extend naturally outward so the scene feels **endless or very expansive**, similar to a large mining region rather than a small isolated pit. Include a **well-defined road network** with wide winding or spiral mining roads that connect the top surface of the terrain to the deeper quarry levels, following the contour of the terraces as they descend. The ground surface should use **natural color combinations**, where the upper terrain and soil areas are mainly **brown**, patches of **green vegetation** appear on outer or less disturbed areas, and the deeper layers at the bottom of the quarry
