Mirror prop

I wonder if it would be possible to make a prop that works like a real life mirror.
I figured it could be neat to have in game, and if it was possible to code this, we would be one step closer to making neat looking portals for the guys trying to recreate the portal gun, and we would have a nifty prop for roleplaying.

When I say “mirror” I don’t mean just a camera that looks back at you.
But a camera that follows your vision giving the illusion of the world being mirrored.

You get the idea right?

You can PM Jinto for his code.

Materialized prop with a rt camera in it looks pretty neat coded in lua.

use some kind of flat base and make it rt material,and make a rt camera looking at u so u cn see ur selves
