OpenFloor

by No Mods

OpenFloor removes the bedrock layer from newly generated worlds, so digging can continue below the bottom of the map.

FabricServer required, client optionalAll rights reserved1.21 – 1.21.10

What it does

Bedrock normally forms an unbreakable floor at the bottom of the world. OpenFloor replaces that block with ordinary terrain during world generation, so the lowest layer can be mined through like any other stone. Builds cover 1.21 – 1.21.10 on Fabric, and the server requires the mod while clients may leave it out.

Key features

  1. Removes unbreakable bedrock

    Worlds generated with the mod have no unbreakable layer at the bottom of the map.

  2. Digging below the old limit

    Players can dig straight down past the former bedrock boundary and explore the empty space there.

  3. Deeper, more open terrain

    Bedrock is replaced by normal terrain, so the underground feels deeper and offers more room to build and excavate.

Questions

Does OpenFloor need to be installed on clients?

No. The server must run the mod, but players can join without it, since only the server needs it.

Does OpenFloor affect existing worlds?

The mod changes world generation, so it applies to newly generated terrain rather than areas that already exist.

What the author says

This mod gets rid of all bedrock in your world, basically unlocking the bottom of the map so you can dig straight through where bedrock used to be. It replaces every bedrock block with normal terrain so the world feels deeper, cleaner, and way more open. You can build down there, mine down there, or just mess around…
