Good tutorial. One thing I didn't care for, and I see it being done in a lot on tutorials for Blender, is that he never changed the color space of the normal map texture node to Non-Color. Using sRGB color space with a normal map in Blender will provide incorrect normals. I know it sounds like you should be using RGB color information with normal maps because they are made up of color vector information to begin with, but that is not the case.

The Normal Map node itself converts the data information contained in the normal maps to the corrected vectors anyway, so you are basically doubling up on the vector data information if you use sRBG color space in the texture node. Always use non-color data for every single texture node that isn't the Base Color or the SSS Color. Everything else in the Principled Shader is a data node only, so use non-color.

The addons are great though. Especially the baking addon. It just kills me when I see people who make tutorials use the sRGB color space for normal textures. That will always screw up the normals on the model.
