Here we have two images, the first one is with everything else in the scene hidden, looks fine. Second one is with everything in the scene showing with black edge lines.
I'm at a lost.
Thanks

It's a pretty small room. what I would do is use a vray sun or maybe a vray sky portal, have a little play with the intensity until you get what you want.
Would be handle to have a screen shot of the render setup.
