Another Overworld
by Veydiz.
Another Overworld adds a second dimension that is generated with the same terrain, biomes, ores and structures as the main Overworld, including those added by other mods.
What it does
The dimension copies the Overworld's generation settings when a world loads, so whatever a loaded mod adds to the Overworld also appears in it. Strongholds generate there as well, and the End stays tied to the original Overworld. Players can explore and gather resources in the new dimension without losing anything from the main world, which makes a single save feel larger.
Testing covered biome and terrain mods such as Terralith, Tectonic and O' Plenty, plus Alex's Caves, Mekanism, GregTech CEu, Cataclysm, Ice and Fire, Towns and Towers and the WDA mods. The mod works in singleplayer and on servers. It is published for Forge and NeoForge across 11 release versions, 1.18.2 – 1.21.1, and it is server-side only, so players join without installing it. It is released under All rights reserved and is not open source.
