Hi,

I am following Scott Keating's presentation (SIGGRAPH 2017 - Lighting and Rendering) where he shows that he uses Principled Shader's “disp” input to create displacement on the grid object. But it does not work as he shows. I want to know where is the problem.

On the principled shader have you enabled under the Displacement tab the option “Enable Input Displacement”? I think he forgot to say it at the beginning

Thank you Andrea for reply. Yes, it could be better if he had said it beforehand. Otherwise I had to experiment to reach to that given point to follow him properly.
