Of course moving further away from an object will make it less sharp since it occupies fewer pixels, but I'm not talking about sharpness here, I'm talking about PBR.
And no, moving closer to the surface of an object should not make it look more dull with PBR. One of the most well known examples of well implemented PBR out there is probably Ryse, and the
main characters armor certainly doesn't start looking dull and plasticy when you move closer to it
Also could you give me an example of where you think the indirect lighting in GoW4 looks better than Paragon?, cause I'm really not seeing it.
And as far as UE4 looking plasticy even with PBR, it is perhaps not as good as Cryengine, but I would still dare say that Paragon does a much better job in this regard than GoW4. Just have a look at the
character models and their different skins, in particular the Master skins.
And Paragon isn't equally limited by the fact that it's a PS4 game?
