if you making fun of unreal engine 4 you are making fun of shenmue 3 because shenmue 3 uses unreal engine 4 also I hope the shenmue 3 rain is a lot better because that rain effect not good
Screen reflections in UE4 are fucking amazing, and I don;t think there's much to this than a shader that bumps the roughness/gloss... There are quite a bit of particles (also the depth is a little lacking).
