How to Build Themed Backrooms Maps with Custom Props

Decorating Rooms with Custom Props

If you want to build your own survival horror map, switch to Creative mode to browse the mod's decorative blocks. Search your inventory for the custom props, computers, and special doors to turn plain vanilla corridors into eerie indoor complexes. Place special doors between hallways to break up sightlines during chases, and set computers onto desks to detail empty rooms. You can also place vanilla chests containing defensive knives so players exploring your map have gear to fight back.

Matching Monsters to Each Zone

Once the structure is complete, use the dedicated spawn eggs to match creatures to your room themes:

  • Unlit Corridors: Place Smilers—along with their spider and fog variants—in dark halls where their glowing faces stand out.
  • Narrow Passages: Add Skin Snatchers and Hounds to tight hallways built for tense, fast-paced chases.
  • Party-Themed Rooms: Populate decorated party areas with hostile yellow Partygoers.
  • Deep, Overgrown Zones: Build dense, overgrown rooms with vanilla foliage and place Clumps and Wretches inside.

Switch to Survival mode afterward to walk through your layout, checking that the dark rooms feel tense and the custom sound effects carry well.
