Dimension Expansion
by DarkLotus781
With Dimension Expansion installed, players can reach several new dimensions through teleporter blocks, each one a themed world for mining and exploring on NeoForge 1.21.1.
What it does
Dimension Expansion adds new dimensions to the game, reached through teleporter blocks. Several of them are built as resource worlds: a flat or superflat layer of stone, deepslate, netherrack and end stone packed with ores, with caves and caverns in places and a higher terrain height near Y=208. Solid bedrock marks the bottom of the world between -64 and 320, so large-scale mining and automation builds have room to work. Hostile mobs are present but can be adjusted in their behavior and spawn rates.
The mod draws on the idea of mining dimensions from other modpacks and on the Stoneblock format, and it is meant as a peaceful alternative for gathering resources. Its dimensions are configurable through datapacks, so a modpack developer can change noise settings, block and light rules, ores, biome features and mob behavior without editing code. Simple Burnout Torch is required and must be installed beside it. The server and every player need the mod installed. Files target 1.21.1 only, and the latest NeoForge build is 1.2.9, dated 2026-08-07.
Key features
Teleporter-linked dimensions
Teleporter blocks give access to the added dimensions, so travel between the normal world and each one is a placed block.
Resource dimensions
Superflat worlds made of stone, deepslate and other base blocks, filled with ores, with caves and caverns in places.
Datapack configuration
Noise settings, ores, biome features, block and light rules and mob behavior can be changed through datapacks, without code changes.
Deep dark dimension
One dimension is an underground realm of constant night and thick darkness, with a deep, hostile setting.

How it compares
Nothing Dimension is client and server, open source under the GNU General Public License v3.0 only, and built for 1.21.1. Dimension A: Resource World is client and server under All rights reserved, and covers 1.21 – 1.21.1. AdvancedTeleporters is client and server under the MIT License, and built for 1.21.1, so it focuses on teleporters rather than added dimensions.
