How to Set Up PBR Materials In Blender
A tutorial showing the basics of setting up PBR (Physically Based Rendering) materials in Blender, from sites such as TextureHaven. I'm using Blender 2.92 in this video, but it should work on pretty much anything after 2.8.
This includes setting up materials using the Principled BSDF shader for both EEVEE and Cycles, covering different types of maps such as Normal, Roughness, Specular, Diffuse (aka Albedo or Colour) and Displacement amongst others.
