What it does

The mod adds a set of Backrooms-themed blocks, including a wallpaper block crafted from an ender pearl, yellow concrete and amethyst shards, and a portal block that leads into the rooms. Suffocating sand and noclip and crouch-related blocks are also included, and the design leans toward the rooms rather than a full dimension. Installation covers the server and each player's game. Fabric API and Forge Config API Port are required, and the code is open source under the Apache License 2.0. Files cover game versions 1.21.11 – 26.1.2, with 0.0.24 for 26.1.2 as the latest beta file.

  2. Portal block

    A portal block provides an entry into the Backrooms from the surrounding world.

  3. Suffocating sand

    Suffocating sand is added as a block, and players can choose where it is placed.

What the author says

In order to noclip, crouch on the block. Craft a wallpaper block with an ender pearl, 1 yellow concrete, and 4 amethyst shards. Noclip into it. IT IS NOT A PORTAL BLOCK. Suffocating in sand will not take you to the desired destination. Unless your goal wasn't the rooms at all.
