About this project
What does Another Overworld add?
🌳 ANOTHER OVERWORLD 🌳
A second Overworld, just for you.
Another Overworld adds a brand-new dimension: a true second Overworld, generated exactly like your own. Same terrain, same biomes, same ores, same structures... including the ones added by your other mods. Double your space to explore and gather without losing anything that makes your world unique.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
🛠️ HOW TO USE
1️⃣ Craft the Overworld Portal block.
2️⃣ Place it wherever you like.
3️⃣ Right-click it.
4️⃣ Welcome to the other Overworld! Right-click the portal again to head back.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
🧪 COMPATIBILITY
The dimension copies your Overworld generation when the world loads: whatever grows in your Overworld grows here too. Tested and working with, among others:
✅ Biomes & terrain: Terralith, Tectonic, Biomes O' Plenty, Alex's Caves and others...
✅ Ores: Mekanism, GregTech CEu and others...
✅ Structures & creatures: Cataclysm, Ice and Fire, Mowzie, Towns and Towers, WDA and others...
And more broadly, any mod that enriches the Overworld. 🌐
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
📌 GOOD TO KNOW
🔸 The dimension shares your main Overworld's generation.
🔸 Strongholds do not generate there: access to the End stays tied to your original Overworld.
🔸 Works in singleplayer and on servers.
