personaldimension
by RUADOU
Players who want a private world of their own can use personaldimension, which lets them create and shape a personal dimension to explore.
What it does
Each player can create a personal dimension and decide much of its shape, environment and rules. Inside it, the player can set several waypoints for quick travel between places. Waypoint management keeps those teleport points organized, which suits larger builds that span more than one area.
The mod can record biomes found in the Overworld and apply them inside a personal dimension, and it can modify the characteristics of existing biomes. Lightning strikes and mob spawning can be influenced with filters, so a dimension can follow its owner's rules for who appears and when. The author notes that the mod was developed with help from AI tools.
personaldimension runs on Fabric and NeoForge, and it requires Architectury API on both loaders. A server running it needs every connecting player to have it too. Files target 1.21.1 only, with the latest file 1.0.2 for 1.21.1, and the code is open source under the MIT License.
