About this Mod

This mod, as featured on my channel, will add 5 new dimensions into minecraft
These dimensions loosely follow the backgrooms lore.
Be aware, this mod is not perfect and was made for entertainment purposes, and will likely not be updated often.
Levels:

Level 0
Level 2 (+1 on the same dimension)
Level 7
Level 11
Level 10
Entities:
Bacteria
Smiler
Hound
Skinstealer
Weeper (custom entity)
The Thing
Death Moth

Again, this was made for fun and entertainment, so the mod has several issues in terms of structure generation. I have done my best to incorporate work arounds where possible. Also make sure to watch my video on it for more information.

Frequently Asked Questions

Backrooms server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.4). You can switch loaders with one click in the panel.

Is Backrooms compatible with fabric?

Backrooms officially supports fabric for Minecraft 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Backrooms – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Backrooms consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
