This attempts to fix MC-237017, a bug that fills all caves below -54 with lava.
With this mod, the lava level is tied to the bedrock level instead of being hardcoded, making it possible to generate caves hundreds of blocks deep.
Serverside only.
NORMAL VERSION:
This has no real use if you don't use a datapack or other means of deepening your world below -64!
PLUS VERSION: work in progress
Includes a datapack to expand your world from 640 to -512 making it effectively 1152 blocks tall.
It also includes rudimentary support for ores W.I.P.! but some things might still be out of place.DISCLAIMER: Your computer will die!
ADDONS / SUPPORT
Most mods should work well and expand into the deeper world, some may only generate in the normal range tho.
I suggest checking out Volcanic Caverns by F1ashFyre as it goes really well together because the caverns will only generate at the low end of the world.
Quark Stuff also seems to generate fine in the deep parts of the world.
Direct mod support for many mods structures & ores will be added eventually and listed here. If your mods generation scales dynamically and works with this, be sure to contact me through github so i can add it here!
