FoFlatAllDimensions
by Carrotio
FoFlatAllDimensions lets a new world on Fabric generate flat terrain in the Overworld, Nether and End through the standard World Type selector.
What it does
The mod adds a Flat Dimensions entry to the World Type button on the Create New World screen. Cycling that button until the entry appears gives a flat-style terrain across all three dimensions instead of only the Overworld. It works by using the vanilla flat dimensions world preset rather than a custom terrain generator, so no separate generator code runs alongside the game's own.
Testing builds, map making and clean test worlds are the cases the mod is meant for, since the flat layout removes natural terrain from every dimension. The mod adds no commands, configuration files, items, blocks or custom screens, so it leaves gameplay systems untouched. Installation needs Fabric only; a world created with the option keeps its flat layout.
FoFlatAllDimensions is server-side only, and only the server needs it. The files cover game version 26.2, with 1.0 for 26.2 as the latest build, and the code is under All rights reserved, so the mod is not open source.
