Cataclysm Dimension

by _p1nero

Cataclysm Dimension is a Forge and NeoForge world generation mod that places each boss structure from a companion Cataclysm mod into its own dimension, with unusual terrain around them.

ForgeNeoForgeClient and serverAll rights reserved1.20.1 – 1.21.11

What it does

Each boss structure from the companion Cataclysm mod is assigned to a separate dimension. Every dimension spawns one structure, placed at coordinates (0, 0). The surrounding terrain is built to look distinct from the overworld, so each dimension has its own setting for the boss structure it holds.

A default entry point is included so players can reach the dimensions without extra setup. Modpack authors can turn that entry off and supply their own method of travel. A config option keeps the original generation of the structures in the overworld, and another enables randomized placement. Placement can also be changed through a datapack.

The mod needs both the server and each player to run it, because the dimensions and their structures are generated on the server and must be loaded on the client. Files are published for Forge and NeoForge across 18 release versions, 1.20.1 – 1.21.11, and the code is covered by All rights reserved.

Key features

  1. One structure per dimension

    Each Cataclysm structure is placed in its own dimension rather than the overworld, so the boss sites stay separate.

  2. Fixed spawn position

    Structures spawn at (0, 0) in their dimension by default, and a custom placement type can be added for this purpose.

  3. Optional random placement

    A config option lets structures spawn at random positions, and a datapack can replace the placement type instead.

  4. Keep original generation

    A config option keeps the structures in their original overworld places alongside the new dimensions.

  5. Shader dimension setup

    Shader users can add the dimension identifiers to the dimension.properties file so the nether-like lighting applies to them.

Use cases

Modpack entry points

Modpack authors can disable the default entry and build their own route into each dimension.

Adventure maps

Each dimension works as a separate destination for exploring the Cataclysm bosses in a single world.

Who it’s for: Players who already use a companion Cataclysm boss mod and want its structures placed in dedicated dimensions, and modpack authors who need control over how those dimensions are entered.

Questions

Does Cataclysm Dimension require a companion Cataclysm mod?

Yes. The mod places the structures from a companion Cataclysm boss mod, so that mod must be installed alongside it on both the server and the client.

Do players need to install Cataclysm Dimension?

Yes. Servers that run it need every player to install it too.

Why do the structures spawn at (0, 0)?

The default placement uses fixed coordinates. The random spread config or a datapack placement change alters this.

Can the original overworld structures be kept?

Yes, by enabling the keep structures config, which leaves the original generation in place.

What the author says

This mod place each structure from the Cataclysm mod into different dimensions, with epic terrain. The structure will spawn at (0, 0) in the dimension and only one structure will spawn. If you want to spawn more structures, you can replace the placement type by datapack or enable the "random_spead" config
