Lava Gen Tweaks
by 3x1t-5tyl3
Lava Gen Tweaks lets a server owner move the base sea level of lava during world generation, a setting the vanilla game keeps fixed.
What it does
Vanilla world generation places the lava sea level at a hardcoded height, typically -54. Lava Gen Tweaks makes that value adjustable, which helps when a world needs lava elsewhere, such as a custom underground layer or a deeper lava ocean. Because the setting is read when the world generates, changes apply to new terrain only, and a mod like this is intended to be used before a world is created.
The mod runs on the server alone, so players join without installing anything. It is released under the MIT License and is open source, and the source code is public. It is published for NeoForge only, with a single release, 1.0.0 for 1.21, dated 2024-07-07.
Key features
Adjustable lava sea level
The base lava level that vanilla fixes near -54 can be changed to another height in the mod's settings.
Levels below -64
The tweak allows the lava level to be set lower than -64, which the default world height limits would otherwise prevent.
Server-side configuration
Only the server needs the mod, and the lava setting is changed there rather than on each player's client.
