Importing a character from Maya and Substance Painter

Hello, I am a games design student and I have some problems with my character. I created a low poly character which I then retopologized, created the skeleton, painted weights, and I unwrapped the model. Then I created high poly version of this character for baking in Substance Painter. After I have done textures in the Substance Painter I exported it to unreal engine together with character skeleton. My problem is that after I set the textures the character still looks like low poly even if I baked it. This is first time when I’m creating a character so I’m asking you for any links or websites that will help me with the importing process or just explain me this process here. Thank you for any help.
