How to create a model like JBL CLIP+ SPEAKER

I’m using VRAY. And for UV unwrapping 3ds max. the problem is when I export to obj it looks not the same. Look screenshots.




But if I export from SU as 3ds with welded vertices it looks fine. But that plugin can export only as obj file format.

And I just tried to unwrap a dome mesh using view align and get distorted resuls. Where am I wrong?
