About this Mod
Lavaloggable
Bring balance to the fluids!
This mod extends Minecraft’s familiar waterlogging mechanic to lava, letting certain blocks safely coexist with molten rock instead of removing it.
Features
- Adds lavalogging support to:
- - Stairs
- - Slabs
- - Fences
- - Walls
- - Copper grates
- - Anvils
- - Iron bars
- By default, only non‑flammable variants (stone, metal, etc.) can be lavalogged.
- Behavior is fully configurable via a simple JSON file, so you can whitelist blocks to your taste.
Why use it?
- Expands building possibilities in Nether bases and lava‑themed builds.
- Keeps parity with waterlogging.
- Lightweight, vanilla‑aligned, and designed for compatibility.
