DimLib Mod (1.21.1) – Manage Custom Worlds Live Without Server Restarts

DimLib Mod adds live dimension management tools to Minecraft servers. It lets server hosts create, clone, and remove custom worlds in real time without restarting the game. The mod also updates world lists for connected players and stops the experimental settings warning screen from popping up.

Features:

• Adds the ability to create and unload custom worlds while the server runs.
• Clones dimension types and world generators from existing templates into new spaces.
• Syncs live world changes to players who also have the mod installed.
• Hides the experimental settings popup when loading modified worlds.
• Keeps saved world files safe on disk even after a dimension is removed from the active list.
• Provides in-game chat commands to inspect world settings on demand.

Commands:

• /dims add_dimension <newDimensionId> <preset>: Adds a new dimension based on a chosen preset.
• /dims clone_dimension <templateDimension> <newDimensionID>: Copies the world generator and dimension type of an existing world to create a new one.
• /dims remove_dimension <dimension>: Unloads an active dimension without deleting its saved chunk files.
• /dims view_dim_config <dimension>: Displays the dimension type ID and chunk generator settings for a world.
