Proof of my idea that a Gravity Room can be made.
I made a room, copied and rotated it. Then placed several prop_portal and made the Cube(s) activate the portals.

There are Two Treats.
One: There is a Cube placed where a Portal Opens; First time a Cube is picked up it comes flying in, so watch out.
Two: I placed the first Cube to make the player fall into the portal automatically. Then, when testing, I had to make some more cubes.

I hope this spawns some interesting maps. In the vmf, file you can see I used 6 portals, in 3 pairs. I covered all the Portal-able areas with prop_portal and activate and deactivate all of them. This eliminates the players own portals, and other imaginary issues (including the prop_portal Active issue).

(This release, is to encurage Gravity Room Development)
