Nucleoid Creator Tools

by NucleoidMC

Nucleoid Creator Tools gives map builders a set of tools for making maps for the Nucleoid ecosystem, with workspaces, regions and bounds handled in the game.

What it does

A map workspace is a separate dimension where a builder works on a map. Workspaces can be created with custom chunk generators and opened like a regular dimension, for example a bedwars:nether dimension that behaves like minecraft:nether. Players join a workspace through a teleport, and once inside the dimension is free to build in. Entering a workspace shows a box outline of the map bounds, drawn with particles.

The map bounds are defined by two corners, an axis-aligned bounding box, and an origin block position. Each workspace is set up with an id, its bounds and its origin, and the origin decides how the exported map is placed. Setting the origin too high or too low can push part of the map outside its bounds, and a map origin set below the lowest y of the bounds moves the exported map downward. The workspace is exported as a map template file that can be read by the Nucleoid ecosystem.

The mod is server-side only and is released under the GNU Lesser General Public License v3.0 only. It is open source, with public source code and an issue tracker. Files are published for Fabric and Quilt, across the game versions 1.19.3, 1.19.4, 1.20.1, 1.20.2, 1.20.4 and 26.1.2. The latest Fabric file is 0.2.3+26.1.2 for 26.1.2, published 2026-05-20.

Key features

  1. Map workspaces

    Each workspace is a dimension where a builder works on a map, joined by teleport and exported later as a template.

  2. Custom chunk generators

    Workspaces can be created with custom chunk generators, so a map can use a terrain type other than the default.

  3. Bounds by two corners

    A region of the map is set by selecting two corners, shown as an axis-aligned box that the builder can match to the desired shape.

  4. Origin setting

    The origin block position controls where the exported map sits, and a wrong value can move it outside the bounds.

  5. Named regions

    Regions are named and read by the game code to mark areas where something happens, with the same name used for several regions.

  6. Block selection

    Right clicking a block shows a particle box, and a second right click picks the block being looked at as the second corner.

Questions

Does Nucleoid Creator Tools need to be on the client?

No. It runs on the server alone, so players need nothing extra to join.

Which loaders does Nucleoid Creator Tools support?

It is published for Fabric and Quilt. The latest Quilt file is 0.2.2 for 1.20.4, published 2024-02-13.

What happens if the origin is set too high or too low?

The map can move outside its bounds. A map origin set below the lowest y of the bounds moves the exported map downward, so the origin should be checked before export.

What the author says

The first step to creating a map is opening a map workspace. A map workspace is essentially just a dimension that you can build within, which can later be exported into a map template file readable by Plasmid. An empty void map workspace can be opened by running: /map open (e.g. /map open bedwars:cubes) The required…
