Nether Lava Source Conversion

by Chacken

Nether Lava Source Conversion makes lava in the Nether form infinite source pools, the way water does in the Overworld.

What it does

In vanilla Minecraft, the lavaSourceConversion game rule makes lava behave like water everywhere. This mod limits that behavior to the Nether, so lava in the Overworld keeps its normal flow. The game rule must be left off for the mod to take effect.

Key features

  1. Nether-only source conversion

    Lava in the Nether can form infinite source blocks, while Overworld lava is unchanged.

  2. Infinite Nether source pools

    Two lava sources placed in the Nether can be used to create a self-refilling pool.

  3. Game rule compatibility

    The lavaSourceConversion rule must stay off so that the mod's behavior applies.

InfiniteLava is server-side only and uses the MIT License, but it is not open source. Create: Infinite Lava Block is open source under the MIT License and needs both the server and clients. AquaLava Survival also needs both sides and is not open source.

Questions

Does Nether Lava Source Conversion need to be installed on the client?

No. The mod is server-side only, so players can join a server running it without installing anything.

Why does infinite lava not form in the Overworld with this mod?

The mod restricts source conversion to the Nether. The vanilla lavaSourceConversion rule would apply everywhere, so it must be turned off.

The vanilla mojang lavaSourceConversion will make lava act like water EVERYWHERE. This mod makes the source conversion…
