Second Overworld
by creamers inc
Second Overworld, a mod by creamers inc, adds an identical second overworld dimension that players reach through a portal built from oak logs and planks.
What it does
Players build the portal frame from oak wood logs and planks, then light it with dirt, and the frame opens a route into a dimension that copies the overworld. Each world can hold this extra overworld next to the original, so one world does not have to be the only place to explore.
The mod is in the Adventure category, with utility and world generation tags. Servers that run it need every player to install it too. Files are published for Forge and NeoForge, for five game versions 1.16.5 – 1.21.1, under the Creative Commons Attribution 4.0 license, and the mod is not open source.
Key features
Identical second overworld
The added dimension mirrors the surface of the main overworld, so terrain and biomes look familiar when players arrive.
Portal from ordinary materials
The portal frame is built from oak logs and planks and is activated with dirt, so no special crafted items are needed.
Separate space for building
Players who want a second area for large builds or experiments can keep it apart from the main world.
Multiplayer dimension
The dimension is available on servers, so every player who joins the server can use the portal.

Use cases
Keeping the main world clear
Players who want large projects can place them in the second overworld and leave the original world as it was.
Experiments with explosives
A separate overworld gives players room to test large explosions and heavy construction without damaging their main base.
Who it’s for: Players who want a second overworld to explore or build in, and server owners who want to offer an extra dimension to their players.
How it compares
Another Overworld is server-side only, so players can join without installing it, and it is published for Forge and NeoForge across 1.18.2 – 1.21.1 under All rights reserved. Nightworld is server-side only and covers 1.19.2 – 26.1.2 under a custom license, with Fabric, Forge and NeoForge files. Second Overworld instead needs both sides and targets 1.16.5 – 1.21.1 for Forge and NeoForge.
