About this project

What does Flat Dimensions add?

Flat Dimensions

This is a datapack that overrides the default world generation to cap the terrain at sea-level for the Overworld, Nether, and End, so its kind of like having the "Overworld" Superflat preset applied to all dimensions, with all biomes and structures. Except it also has caves, oceans, rivers, and ponds.

"Aw I wish it was just like the 'Overworld' Superflat Preset, where it doesn't have caves..."

Check out my No Caves pack! It now has support for this pack, meaning you can have a caveless overworld and nether for a true superflat experience!

Please note when using this, just add the datapack on the world creation screen and create a world like normal. You should not to use the Superflat Preset.

Why does it replace the default overworld, and why can't it use a preset? Datapacks allow creators to edit many things in Minecraft, but some things are hardcoded, meaning they require a mod to change. Datapacks do allow for custom superflat presets, but unfortunately they only allow for single-biome worlds. Datapacks also allow for custom world presets, but unfortunately, any changes outside of the terrain must be done globally, meaning anytime I need to change the structure or feature generation to get it to fit, it would change it for all presets. If I made a preset and someone was using the mod version of this pack, then they could easily be unknowingly altering vanilla worldgen!

Superflat Version

Compatibility Notes:

This pack should work with biome mods (although there may be some weirdness, depending on how the mod was made).

If you've never used terrain mods together, you should know that they generally override each other. The same case is for this mod.

Generation Notes:

Pre-1.21

  • Nether Fossils will spawn below lava in the Nether, for technical reasons, a solution to this wasn't available until 1.21.
