Thank you for the explanation! It makes perfect sense now.

Sorry, my bad. I've used Anything Goos and love it, but I think I confused this "Bevel" in Shader Plus function with Anything Grooves.

Is there a reason to use Anything Grooves over Carrara's own displacement?

Also: how does "Bevel" fare in terms of render time? Does it add more than what additional geometry would have added or less? Would you use it in animation?
