You mean how far the camera is from the player doesn't make any effect on how much sharp a surface will look.Huh? The visual impact of PBR shouldn't be affected by camera angle and distance in this way at all.
I mean the closer to the surface we get the more dull the PBR/PBSed surface will become.
I observed this while playing evolve(an FPS).
And indirect light in paragon is not up to the game in OP.
Anyway ue4 looks plastic even with PBR as compared to Cryengine.
