I wanted to make a tutorial for a long time now, but all things I could think of had been covered already. This topic at least to my knowledge hasn't been covered yet, and it's so important and easily overlooked that I thought this would be a good candidate.
If you work with Blender and do some texture work then maybe you'll get something useful out of this. If you do or don't lemme know so I can improve and make more if there is demand for it ^^
I made an example blend file which you can download here

It includes the setup you see in the tutorial complete with the nodes.
