Go beyond the vanilla height limit with just 3 steps!


WARNING: Currently a dimension gets corrupted and reset if you try to modify the max height. Although I did implement a way to directly insert the datapack into a world, you should only use the last option of world selection which is to generate a data pack in the current folder. You can then add this data pack in the single-player world creation menu, before it's generated. Do not select an already existing world (just yet).

Besides increasing height, this tool can also be used to limit the height (e.g. prevent building on the Nether roof). The tool is a console application available for Windows, Mac OS and Linux (64 bit). Run the software and you'll be prompted to answer a few questions, just type in the number of your choice. First off, what world you want to modify:

World Height Unlocker (1.17+) Minecraft Mod

Select a dimension:

World Height Unlocker (1.17+) Minecraft Mod

And lastly, type the height and press enter. A custom data pack will be generated in that world that modifies the max build height to be whatever you specified.

If you are not on Windows or use a custom world saves path, you can edit the WorldSavesPath value in settings.json file that's generated on first launch.

What's the maximum height limit we can set?

Also, does it allow us to go deeper more or higher more? Would be pretty cool if we can unlock the world height going down to have more caves and stuff to mine!

Idk about the maximum, but the height should always be divisible by 16.

And no, it does not affect world generation.

Hello! Im am having some issues trying to use this. When I try to use it, I increase my limit but when I open the world, the height limit has not been increased. If you can help me out or link me to a source that can help me that would be great!

I think you have to create the world with the datapack enabled (in the data packs section of the creation menu). Also make sure it's vanilla 1.17. The software has an option to just generate a data pack, without injecting it in a world, that's what you want (also see orange warning at the start of this submission). I think the world height needs to be dividable by 16, so for example: 256, 512 or 1024. After applying the datapack you could try /datapack list to see if it shows up, make sure to exit and re-open the world though if you applied it while having it open.

Just downloaded and it worked for me. Did you unzip the application before running it? Also make sure you do not select an existing world just yet (it will corrupt it), make it generate in current folder instead. Drop the generated pack into the data packs section in the world creation screen.
