This tutorial examines the creation of polygonal meshes with high quality curvature to produce better reflections. Its geared towards artists who have experience in modeling complex hard surfaces such as cars but are looking to have a better grasp on the subject.
While this is a modeling tutorial it will not go into any details of the basic process of creating the mesh, specific tools or matching the reference proportions.
The level of quality that this tutorial deals with relates to rendering an object with continuous reflection streaks across it. If all what you need is something reflecting an HDR sky environment and you don't mind some reflection distortions that the untrained eye won't catch then this is not for you.
