backroom building blocks
by stevehuman
Backrooms Building Blocks, a NeoForge mod by stevehuman, adds decorative blocks inspired by the Level 0 setting of the Backrooms.
What it does
The mod adds building blocks modeled on the Level 0 look of the Backrooms, with wallpaper and drop-ceiling pieces, glowing tube lighting and other decor meant to recreate that setting. Map builders can use the blocks to shape rooms and corridors that feel like the original.
It is an early alpha: the release is 0.0.2 for 1.21.1, published on the alpha channel. Some textures, models and features are still rough or unfinished, and block designs may change in later updates. More Backrooms-themed blocks are planned, and feedback and suggestions are welcomed by the author to guide future work.
The mod is built for NeoForge and works with 1.21.1 only. It runs on the client and server, so the server and every player need it. The code is not open source; it is released under All rights reserved.
Key features
Level 0 wallpaper and ceiling tiles
Yellow wallpaper and ceiling tile blocks reproduce the walls and drop ceilings associated with the Level 0 setting.
Fluorescent light blocks
Fluorescent light fixtures give rooms the flat, buzzing lighting that defines the Backrooms atmosphere.
Additional decorative blocks
Other decorative pieces round out the set for furnishing corridors, offices and similar spaces.
Early alpha content
The set is a first release, and more Backrooms-themed blocks are planned for upcoming versions.

Use cases
Immersive map building

How it compares
Backrooms blocks and stuff is a NeoForge mod for 1.21.1, run on client and server, released under All rights reserved and not open source. Backroom Wallpaper is also a NeoForge mod for 1.21.1 with client and server environment and All rights reserved license, not open source. Backrooms Resources [ALPHA] targets NeoForge 1.21.1 and works on either side, and neither needs it, so it can run alone on a client or a server; it is also not open source.
