I'm noticing that the preview for the tiles on the freepbr.com site is a little more shiny/glossy. see attached. Curious if the PBR shader has fresnel built in?
Cheetah3D uses the GGX BRDF + Fresnel for specular reflections like described in the Disney paper.
It's not really possible to compare these images since Cheetah3D uses a completely different light setup. And the light setup have a massive impact on the appearance of the surface.
