So I may be missing something here, but the point of this particular exercise seems to be to make fresnel responsive to roughness. But isn’t that automatic with the new Principled BSDF shader so all this is obsolete?
Yes, but parts of the course are done with an old version of Blender.
And in my opinion, it can not harm you knowing the principles of rendering.
Happy rendering.

Ok, thanks. Important to know at least. I haven’t watched every single video in this course (there are a lot of them!) but I don’t think there’s been a video for the new shader yet and there probably ought to be one.

No, I don’t think so. But you can always see Blender Guru https://www.youtube.com/watch?v=4H5W6C_Mbck
