Dynamic Dimensions AR Edition

by MarvinEckhardt

Dynamic Dimensions AR Edition lets a server create dimension levels on demand, using the primary level's data as the basis for each one.

What it does

The mod is a fork of Dynamic Dimensions and builds on the original's approach to creating extra levels at runtime. Its main differences from the original concern how levels get their data, which comes from the primary level, and a wider spread of biomes across the generated worlds, so generated levels draw on a more varied set of terrain.

Dynamic Dimensions AR Edition requires Bad Packets to run. It is published for NeoForge only, for Minecraft 1.21.1, and runs on client and server, so every player on a server needs it as well. The author also notes a critical bugfix to run on NeoForge, which is included in the 0.9.1 build. The code is under the MIT License, and the project is not open source.

Key features

  1. Dynamic level creation

    Dimension levels can be created while the game runs, rather than being fixed in advance by the world files.

  2. Primary level data

    New levels take their settings from the primary level, so generated dimensions stay consistent with the main world.

  3. Wider biome distribution

    Biomes are spread more widely across generated levels, giving each one a more varied set of terrain.

  4. Fork of the original

    The project is a fork of Dynamic Dimensions with its own changes, documented by the author as differences from the source mod.
