World Dimension Nexus
by Kaworru
World Dimension Nexus is a serverside tool for creating, importing, exporting and managing custom dimensions, warps and portals on a NeoForge server.
What it does
A server owner can create an unlimited number of custom dimensions, each with its own world type and game mode. Creative, survival and adventure modes can be set per dimension, and dimensions can be moved between servers through import and export. Players do not need the mod on their client, since the tool works from the server side alone.
Players can travel between worlds through private warps for personal bases and public warps for community areas and landmarks. Automatic fallback systems and void protection aim to keep travellers from falling out of a dimension, and auto-teleport rules can move players between dimensions on set triggers and target coordinates. A quick start guide lists a limited set of commands to begin with.
The mod requires NeoForge and is published for 1.21.1 only, with the latest file 0.11.0 released on 2025-08-02 on the beta channel. Commands and features may change before a stable release, so a test world is advisable before using a main world. The mod is open source under the MIT License. Dimensions created at runtime need a server restart before their features and entities work.
