What it does

The blocks are meant for building Backrooms-style areas in ordinary survival worlds, adventure maps and horror builds, including a yellow-walled bunker set underneath an existing base. The author describes the set as giving the damp, desolate look of the setting. Client and server both need the mod, and it is published for Fabric and NeoForge, with files for 26.1.2 only.
