airport terminal 3d model

Create a simplified central airport terminal hub inspired by Beijing Daxing International Airport, not an exact replica, for a Unity airport drone intrusion and LiDAR simulation demo. Game-ready GLB asset with modeling and textures included. One large central hall with clean radial layout and 5 evenly spaced wing connection ports. Each port must have a flat rectangular connection face, same size, straight edge, no decorations or protrusions, easy to attach terminal wing modules. Use solid 3D volume, flat ground contact, symmetrical layout, smooth controlled roof, broad curved roof edge, linear skylight strips, blue-gray glass curtain walls, dark window frames, light gray concrete and metal structure. Avoid twisted surfaces, warped panels, spikes, random parts, holes, broken geometry, thin shells, uneven roof, and overly reflective materials. PBR textures: matte light gray roof, rough concrete, blue-gray glass, dark metal frames. Medium detail, optimized mesh,No cars, aircraft, people
