LavaSweeper
by Hiiragi283
LavaSweeper is a world generation mod that removes the lava traps found in Nether generation, so players can move through caves and structures without that hazard.
What it does
Lava placed as traps across the Nether can make exploring it uncomfortable. LavaSweeper stops those traps from generating during chunk creation, which also keeps the game from loading flowing lava at that stage. The removal applies to the world as it is generated, so the change is made where the traps would otherwise appear.
The mod runs on client and server and is published for Fabric, Forge and NeoForge, covering 21 release versions, with builds for 1.12 – 26.1.2. Each loader has its own file line, with the latest Forge file at 1.0.1+forge1122 for 1.12.2 and the latest NeoForge file at 1.1.0+neoforge for 26.1.2. The mod is open source under the Mozilla Public License 2.0, and its source code and issue tracker are public.
Key features
Nether lava traps removed
Lava traps that generate in the Nether are not placed, so the terrain stays free of that hazard.
Flowing lava skipped at generation
Flowing lava is not produced during chunk generation, which reduces the lava the game has to load at that stage.
Lava light source handled on the client
The lava light source is loaded on the client side, so the rendering side of the lava is tied to the client.
Single purpose
The mod changes only Nether lava generation and leaves other terrain features to the game and other mods.

How it compares
Skniro's Nether and End Ores adds ores to the Nether and End, is open source under the MIT License, and is published for Fabric, Forge and NeoForge across 1.19.4 – 26.3, with both sides needing it. No More Nether Gold Ore removes gold ore from the Nether, is not open source, is published for Fabric, Forge, NeoForge and Quilt across 1.20 – 1.21.4, and only the server needs it. More Lava TFC is a Forge and NeoForge mod for 1.20.1 – 1.21.1 under the MIT License, is not open source, and needs both sides.
