Goal

Create a door that acts as a portal between rooms in VR.

Issues

1. Outside edges of the door show inside another room. Only the inside of the door should show inside another room.
2. Entering a portal from behind does nothing. Should disable ability to enter a portal from behind. Can't fix this with walls since a player can walk through walls and the stencil buffer won't render walls well. Recommend finding a way to get the door to disappear after the player goes through it.
