ChamferZone has released a wonderful tutorial (divided into two parts) long about 3 hours concerning the creating, mapping, baking, and PBR textures of a blade.

In the first part Tim Bergholz (Senior 3D Artist at Digital Extremes and in the past at Ubisoft Toronto and Crytek) will accompany us in the lowpoly and highpoly modeling of the blade with attached unwrap, all created in 3dsMax2017 (you can still use any modeling software 3d). In the second part we will see the right workflow of Baking and PBR Texturing in Substance Painter 2.
