Towering Heights
Towering Heights lifts the world height limit of Minecraft so that terrain and builds can reach up to 16384 blocks, far above the vanilla default.
What it does
The mod raises the maximum world height from the vanilla default to 16384 blocks. The horizontal scale is large as well, with the X and Z axes described by the author as 16.8 and 8.4 thousand blocks...
Because of the scale, the mod uses a noticeable amount of memory. The author suggests allocating around 4 to 6 GB, with more when other mods run alongside it, and recommends the ZGC garbage collector for a smoother experience.
Distant Horizons does not render terrain above 6000 blocks, and Voxy does not work at those heights either. The author states these limits cannot be fixed with this mod, and the mod requires a custom Distant Horizons and Voxy fork to be used at extreme heights. Towering Heights is a Fabric mod for 1.21.11 and runs on client and server, so the server and every player need it. Files are released under the MIT License and the mod is not open source.

This mod greatly pushes minecraft's maximum world heights (upto ±16384, not this by default), at the cost of X axis (±16.8m blocks) and Z axis (±8.4m blocks). To my knowledge, this is the only mod for newer versions which can reach this sheer scale. This mod can be used with large terrain generation but generally…
