SecretRooms-Unofficial
by bay4lly
With SecretRooms-Unofficial, blocks disguise themselves as the stone and wood around them, and some still work as hidden triggers, ladders or redstone.
What it does
The mod adds camouflage blocks that look like normal blocks in the surrounding world but carry hidden functions. Ghost Blocks appear solid yet can be walked through, One-Way Glass lets a player see out while others cannot see in, and Secret Levers and Buttons trigger redstone from a place that looks like plain wall. Invisible ladders, called Secret Clamber, give vertical escape routes, and Secret Redstone runs hidden power lines through a base. Players can conceal diamonds in plain sight or build a base that only they can enter.
The mod is an unofficial port of the Secret Rooms mod by bay4lly, and it runs on Forge 1.20.1 and NeoForge 1.21.1. It is client and server, so the server and every player need it. The code is open source under the GNU General Public License v2.0 only, and source code is linked publicly. Files cover 1.20 – 1.21.1 across seven release versions, with 1.21.1 builds on NeoForge and 1.20.1 builds on Forge as the latest files.

How it compares
Secret Blocks (multi-loader) is open source under the GNU Lesser General Public License v3.0 only and covers Fabric, Forge, NeoForge and Quilt for 1.18 – 1.20.1, so it reaches Fabric and Quilt players that this mod does not. Modern Glass Doors(Forge) is client and server, is not open source under the MIT License, and covers 1.20.1 – 1.21.1 on Forge and NeoForge, adding doors rather than hidden blocks. Secret CE Doors is Forge-only for 1.18.2 with the same client and server environment, not open source, under the MIT License.
