Explanation of Disney's principled BRDF [video]

The linked video is an in depth and step-by-step explanation of Disney's "Principled"[0] BRDF shading model.

The latter part includes a really great explanation and visual demonstration of each of the controllable parameters--which is very also helpful for artists who use BRDF in 3D packages such as Blender.

(Includes math/maths content but presents it in a more accessible manner than one might anticipate.)

Fair warning: Acerola's stylistic choices may be... an acquired taste but the content of the videos is absolutely worth acquiring the taste for. :)

[0] Including why it's called "Principled"--which I hadn't realised I did actually want to know. :)
