I've been looking for one and can't find one.
I don't quite understand what you mean, you're looking for a quiz? About V-ray?
Why is it that you expect a quiz after that video?
There is a quiz at the end of chapter 4, as with each of the 3 chapters before this one.Chapter 5 has no quiz, and chapter 6 has an exercise.
This was purely an attempt at humor, I liked the video and thought it would be funny if there were a short quiz. ย What has Fresnel? ย Sorry for the confusion.
๐ Haha! We failed that one question quiz.
