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.

FAQs

Q: Will this be ported to any other modloaders?
A: I do not currently have plans to port this mod.

Q: How do I change which blocks are lavaloggable?
A: Inside the .jar file, there are 2 lavalog_eligible.json files (one for server side and one for client). You can add or remove blocks using their namespaced ids (minecraft:oak_stairs or yourModID:yourModBlock).

Q: If my mod's eligible blocks list is different from my server's, what will happen?
A: The mod will default to the server's eliglble list when in a multiplayer world.
