This mod allows for (almost) unlimited world height and depth, by dynamically loading vertical sections of the world, just like Minecraft does in horizontal direction.

WARNING: This mod WILL break many other mods in hard to predict ways. Most of the incompatibilities cannot be fixed without changes to other mods. Incompatibility list on CurseForge doesn't lists only a few of them!

Currently Cubic Chunks may break JEID. It may corrupt your world, without any way to recover it.


Versions 1.10.2-0.0.871.0, 1.11.2-0.0.856.0 and 1.12.2-0.0.852.0 contain CubicWorldGen sub-mod. All newer versions need CubicWorldGen installed separately if you want Cubic Chunks world generators.


1.14.x update - work in progress. Don't ask when. It will be released when it's done.


Mod compatibility

NOT COMPATIBLE WITH MCEDIT, WORLDEDIT, SPONGE or BUKKIT/SPIGOT. NBTExplorer will not be able to edit Cubic Chunks region files.

There are special compatibility tweaks for OptiFine included. Supported optifine versions are:

  • 1.12.2: E2, except CubicChunks 1.12.2-0.0.852, works only with C7-C9, has unfinished support for D1
  • 1.11.2: C7
  • 1.10.2: E7

A plugin for WorldPainter will be available soon.


Other than that, many mods are likely to break in unpredictable way. Use with other mods at your own risk. Report all compatibility issues to Cubic Chunks, NOT to other mods, even if this is incompatibility with new MinecraftForge version. Unofficial community maintained compatibility list can be found on Cubic Chunks wiki pages.

Versions 1.10.2-0.0.871.0, 1.11.2-0.0.856.0 and 1.12.2-0.0.852.0  may  be compatible with some additional mods that don't work with newer versions, in case a mod was made to be compatible with this older version.

Creating Cubic Chunks world

To create a Cubic Chunks world for the first time, you need to select "more world options" and enable Cubic Chunks in that menu. This will be remembered for future worlds, and saved in config.

For CubicWorldGen world types, you don't need to enable that option, it will always generate a Cubic Chunks world.

Note: on the first load, your build height may be still limited to 256 blocks. This should fix itself once the world is reloaded. This is a known bug.


For servers you need to set forceCubicChunks option to true in cubicchunks.cfg config file.

Note: don't forget to change max build height in if it's from vanilla.


Old versions

Curse no longer shows old versions of alpha files, here are direct links to all of them:


Cubic Chunks has a discord server that you can join. If you have any issues, you can ask there.
