Summary
In this chapter, we learned how smooth normals work and how to use Auto Smooth. You should now also know how to mark edges as sharp and how to retopologize a hard surface object.
Finally, with this chapter done, we should be comfortable using the topology rules that we introduced in the first part of the book. Up until this point, we have exclusively used a quad-based workflow, only using faces that have four vertices and edges. In the next chapter, we are going to explore the use of triangles to reduce the total number of faces on a model.
