NURBS

I'm trying my hand at rendering in UE4. My goal with my current project it to replicate, or get as close to, a rendering I did in Substance Painter inside of the Unreal Engine and I would like some advice on how to do that.

Here is what I currently have:

And this is the render I made in Substance Painter that I am trying to replicate:

As you can see, the two images are very different. If anyone would be willing to share some advice, that would be very much appreciated. Also, I was wondering if it is possible to extract environmental maps from Substance Painter as an HDRI or EXR, or something, and bring them into Unreal. I really like the environmental map I found in Substance.

You could place a post process and do some adjustments there.

The environment maps in substance painter are EXR files stored on your C drive. 
C:\Program Files\Allegorithmic\Substance Painter\resources\shelf\allegorithmic\environments\

it's actually easier to match substance painter to Unreal by using a Aces color profile
