Hey everyone,

I’m working on a 3D diorama Backrooms-inspired scene (isometric cutaway room, ~35° top-down angle). The concept is a small enclosed liminal space with aged yellow wallpaper, a flickering greenish fluorescent light, and a surreal “glitch in reality” feel.

Current key elements:

• Wooden chair partially clipping into the floor (noclip effect)
• Car roof emerging from the ground, as if submerged into the floor
• Wooden ladder leaning into a dark square hole in the wall that leads into complete darkness

I’m aiming for a boxed miniature / artificial diorama feel with realistic materials, grime, ambient occlusion, subtle film grain, and a muted cinematic palette.

I’m mainly trying to push the environment further without overcrowding it.

What I’d really appreciate feedback on:

• What additional objects would make the scene feel more unsettling or “Backrooms accurate” without breaking the minimal composition?
• Any environmental details I might be missing (e.g. props, surface details, lighting imperfections)?
• Anything that would strengthen the “liminal / uncanny” feeling specifically?

Some ideas I’ve considered but haven’t added yet:

• Stains / damp patches spreading up the wallpaper and carpet
• Small puddle with subtle reflection distortion
• Strange writing or drawing on the walls

Would love to hear what else could elevate it visually or conceptually

Thanks!
