About this Mod

Isn't it such a hassle to use external sites just to create custom superflat presets?

Have you ever wanted to create custom presets right inside of Minecraft?

FlatEdit+ (the superior superflat customization system)

FlatEdit+ is a client-side quality-of-life Minecraft mod that overhauls the Superflat World Creation System, giving players much greater control, clarity, and power when designing custom flat worlds.

Frequently Asked Questions

Does FlatEdit+ need to be installed on the Minecraft server?

No. Modrinth marks FlatEdit+ as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does FlatEdit+ require?

Use a file for fabric, forge, neoforge, quilt and your exact Minecraft version. Supported versions include 26.1.2, 26.1.1, 26.1. Files for different loaders are not interchangeable.

FlatEdit+ is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
