Substance painter textures are rendering out wrong in maya? Also strange artifacting?

Hi ! 
I've already tried trying to find the answer to this, so i'm sorry if i missed another thread answering this question. 
I'm still very new with substance painter, but I've used it for a few models and haven't had this issue before. 

I made my model, put it into substance painter, and then painted on it, and everything looks fine:

I transferred it back into maya, and in the viewport, the textures still look fine:

But then i go to the Arnold renderer and it renders out wrong?

The UV's are the same in both programs.

**Edit: SORRY I think it's just my UV'S! I'm going to try again.

Is there some kind of smoothing goin on.?
Or truned edges?

@oglu
I don't think so. All I did was soften the faces.

Could you upload the hairband here. Would like to take a look.

I tried uploading as a obj file, but it says It doesn't support the file. But i'm starting to think i may have just UV'd wrong and didn't notice until it was on the model, even though it appeared fine in viewport. I thought it would only allow to be textured the way it was UV'ed. Sorry for such a beginner question!
