It's been a while since I touched my Valve Index but I wanna get into VR.
The one thing I could never figure out is how to make my own room.
When you put up the Index on Steam you get put into a little preset room where you can select your library or browse the internet. 
Any time I've added different objects or hang posters onto the walls, the next session I come back everything is reset back to default.
How do I go about making a cool, little VR room for myself when I hop into the Index?
