Uslessness Dimension
by Trckstrcam
Uslessness Dimension adds a small pocket dimension called Useless, entered through a portal built from Uselessness blocks and lit with an Uselessness Igniter.
What it does
The dimension is tiny and barren, so it suits building projects where a plain backdrop is wanted. Players reach it through a portal that is assembled like a Nether portal, but the frame uses Uselessness Blocks in place of obsidian and an Uselessness Igniter in place of flint and steel. The Uselessness Portal block is crafted from two Uselessness items, and a dark black building block is included for construction.
Mobs can spawn inside the dimension and may follow a player back through the portal. Because the space is isolated, many players use it as a quiet place away from their main world. Dirt, stone and useless blocks can be farmed there in large amounts, and the mod adds further useless objects to craft.
Installation covers the server and each player's game. Files are published for Fabric, Forge and NeoForge, with builds for 1.16.5, 1.20.1, 1.21.1 and 26.1.2. The code is licensed as All rights reserved, so the mod is not open source.

What the author says
I added a simple Dimension that is quote on quote useless. Unlike the name suggests this can be a very useful place since you can use it as a safe place nobody knows about. No mobs spawn inside the dimension but you can bring mobs into the portal
