About this Mod
No Sky Limits
Simply changes the build limit in the overworld to 1024, both up and down. Allowing you to build above y=319, and below y=-64.
Terralith Support
Spoiler
If you want to install this to allow worldgen mods such as terralith to make incredibly high mountains, it won't work. You would probably have to modify terralith's biome files. Don't ask me, im not a professional. Actually, do ask me. I would love to help.Warning!!
This datapack might cause extra lag, longer load/save times, and possibly decrease FPS. Not to sure though, so take this with a grain of salt!
