For those who have no money, you can easily recreate the stylized metal textures by following the same method of duplicating fill layers and adding mask editors referenced in the video where Jay textures the wooden handle. The outcome is absolutely beautiful, and a solid alternative if your bank account is a bit dry.
Wait, in one of the previous tutorials you have unwrapped the Wraps using Substance Painter automatic unwrap option, this means that you had to re-import the fbx back to blender, correct? Did you use this option also for the blade or done that manually? What do you do to mask the seams? I would love see a video about that.
