those are tools , and a tools can be usefull, it will depend of Art director , but i’m pretty sure that real time g.i and reflection rendering will not be a hype,
-clearly as a gamer ( and like every gamer i hope ) im tired of screen space reflexion , and fake g.i with dark shadow/penumbra in a full cycle night and day game ( like state of decay 2).
-now as a 3d artist Professional , i will be happy to show to my client their product in real time with real reflection, real g.i ,real refraction ( hope dxr refraction rendering will be introduce to ue4)
