Lava Gen Tweaks
Are you tired of the default lava level? Do you wish to adjust it for a world that goes below -64? Do you want HELL ON EARTH then this mod is for you!
Lava Gen Tweaks' only feature is to be able to adjust the lava-sea-level. Which currently is hardcoded into vanilla minecraft. As such, in order to change it, you'll need this mod!
As it stands right now it's unlikely this will be fixed. So I stand to keep this somewhat up-to-date
Important
DO NOT adjust this setting after world creation. It might break or corrupt your world.
Install
Download NeoForge for Minecraft 1.21 and follow their installation instructions.
After that, drag and drop the mod into your "mods" folder of your minecraft instance.
After install, in the main menu, press on "Mods", click on "Lava Gen Tweaks" and mess with the number to your liking!
Fabric
Once I learn to have multi-loader setup. I might also make a fabric version.
Otherwise only NeoForge is supported for now.
