Here is the image link.  It refers to the new Sci-Fi Villa.  http://www.renderosity.com/mod/bcs/?ViewProduct=110162 

The promo says additional  (mirrored) habitat module prop is used.

Now then, since it is a prop, I'll go with bagginsbill suggestion.  And give it a try.  I'll post my results and we'll go from there.  Of course D3D has a nice paid solution.  He's very talented and very helpful with his products but let's do it by hand because I am incredibly cheap! ;D
