Problem with mirrors.

[hakr]

I was working on this map ( Not my first one, but the first one i think is worth posting ) and in the bathroom ( It just didn't feel right without it ) I wanted mirrors over the SINKS I HAD TO MODEL IN 3D MAX so with mirrors being a new concept for me I read up on 'em. I placed the mirror shader brush and then the misc_portal_surface and tested it AND!!!

I could see myself in it .
But i also could see the room behind it and there was a wall and well the other rooms wall in between. All the outsides were caulked.

Any ideas.

Thanks in advance.
