So I tried to compare:
Albedo mapped to the PBR script, and I plugged in all the pieces (Albedo, Roughness, Metalness, Normal, Displacement)
Albedo and all the pieces mapped to a Glossy shader
The PBR material, at default, seemed to render very fast, and I wasn't sure if I am seeing this correctly.
I ran at 1920 x 1080 res, to a sample limit of 50, because it will render to whatever you set it at...
But it seemed to be earliest done at 50...Fifty, not a mistype....Fifty. (It took 1 second w/4 Titan X.)
And, here is my best approximation on the Glossy of the look the PBR one it gave, I can't match it exactly, they work different somehow. Look how the lighting hits it, it's almost like a different angle or something.
But here is the big thing, at 50 s/px, the PBR render looked good. At 50 s/px, the Glossy render showed hot pixels and was grainy (unfinished), so I included a pic of the HP removal on as well...
But, Look! Is this the future we are seeing?
Octane + PBR = a good looking result @ mega speed?
