liminalness
by dddanpppan
Liminalness is a NeoForge server mod for 1.21.1 that adds an infinitely generated liminal dimension, where players enter, explore and try to find the way out.
What it does
Liminalness adds a procedurally generated backrooms-style dimension that continues without limit. The terrain is built from custom math functions, so a player can end up in a barren world that feels familiar but holds nothing that would make staying worthwhile. Rooms contain portals that are generated at random as the player explores, and chests hold procedurally generated loot.
The mod is designed so that the dimension is found by accident during ordinary vanilla play, not by following a set route. Entry and exit follow vanilla mechanics, and the mod supports servers and clients with new block entities. Liminalness is published for NeoForge only, for 1.21.1, and runs on the server alone, so players join without installing it. It is released under the MIT License and is open source.
Key features
Infinite liminal dimension
An endless backrooms-style dimension is generated procedurally, with terrain shaped by custom math functions.
Random portal rooms
Rooms hold portals that appear at random during exploration, giving players a way to move between areas.
Light-based entry
Right-clicking a bed in a shaded area with light, including sunlight, starts the route into the dimension, and dying returns the player to the bed.
Locate command
A locate command helps players find their way once they are inside, and a block emitting black and purple particles marks the way back to the bed.

What the author says
You find yourself in a barren world straight out of the deepest depths of your mind. There is familiarity, yet nothing substantial to warrant staying. It's not a matter of surviving, its a matter of finding an exit. Don't get lost! right click a bed in an area that has no light, including sunlight.
