After reading about the new Disney Diffuse BRDF, I have been wondering if this is currently the best Diffuse BRDF at the moment? How much more of a difference would this make compared to using a Lambertian BRDF? I have heard of other BRDFs such as Hanrahan-Krueger and Oren-Nayar, are these also better?

    $\begingroup$ Disney's BRDF is pretty much the top of the line as far as diffuse BRDFs go, yes. $\endgroup$ – Quinchilion Jan 19 '17 at 18:30
