Texture in UE looks different from Substance Painter

Hey all, am rather new using the Unreal Engine and am stumped here. I textured a chair in Substance Painter but it looks vastly different when I apply them in the UE. The first image is taken from Substance, the other one in UE.

Also the roughness does not work in the engine, its not like in Substance. Can anyone tell me what I am suppose to do?
