Smooth Edges mess up UV's

[kochamklauny2DWTG]

Hi, I'm working on an animation. I wanted to put my character mesh into Unreal Engine 4, so I can make a scene around it. The mesh looks like this in maya, and on the picture on the right, there is a static version of it subdivided and painted in 3d Coat - my endgoal:

This is the  However in Maya I have a problem with smoothing my mesh properly.

I've tried Modify -> Convert -> Smooth Mesh Preview to Polygons, but after exporting the fbx to game engine, it didn't seem to work. The mesh was looking smooth in maya, but not in other software. 

So after some research I've tried to use Mesh Display -> Soften Edges. The result was mixed:

The mesh in UE4 looks smooth now, but for some reason beyond my comprehension the UV's are messed up. While as you could see on a picture above, the exact same mesh without using Soften Edges was fine. 

I'm lost, it seems like I've managed to solve one problem, just to cause the new one.

Please, send help!

I had this problem too, and after searching a lot of sources, I solved it. First export the smoothed mesh as an fbx file, and then re-import and export the file.
