If the modeling work of Sky City is a high mountain, then the material of Sky City is as difficult as climbing Mount Everest. How to make material for such a huge scene, even if you can UV and hand-draw, will be extremely headache for such a huge workload. Faced with tens of billions of polygons, each model has tens of billions of polygons. For millions of faces, computing UV is a deadly thing. These technical problems will be solved in the course. This technology will enable you to deal with any large-scale scene material problems.
