📋 About This Mod
Terrain Extender
This mod removes the hardcoded limit of entities and terrain from being within the (2048, 3040, 2048) bounds, so now you can have anything anywhere in the world spawning without any issues!
Compatibility
Terrain Extender is fully compatible with Reef Editor and Terrain Patcher. When this mod is present, you can create terrain using Reef editor outside of the world bounds, then load it using Terrain Patcher, then everything will automatically work fine!

With 1,285 endorsements and over 112,000 downloads, it's a popular tool for players seeking expanded building space.
