It's right near the start. It's the room with the door that blows open and startles you in the hallway with two cabinets. Has a fireplace, a table, some chairs, a wine bottle, a vase in the corner, and a tinderbox.
By the way, it probably looks different from anything in the game because I doubled my gamma so it would be easier to see everything.
I gathered all of the physics objects I could find from across the level. Every single one had a place at the table except for the pen in the inkwell, which broke before I could place it properly.
I don't plan to play at that brightness all the time. I just did it for the gathering of props and the taking of these photos so people could see it all. I play the game itself at the normal brightness setting.
