Terralith Data Pack Wiki & Guide
Terralith is a massive world generation overhaul for Minecraft that introduces over 85 unique biomes and dozens of custom structures using only vanilla blocks, creating a diverse and realistic Overworld experience.
Overview
Terralith ~ Overworld Evolved is a comprehensive project designed to revolutionize the Minecraft Overworld's generation. Originally released on July 28th, 2021, it utilizes modern worldgen tools to create breathtaking landscapes, including massive canyons, amplified terrain, and floating islands. The mod adds more than 70 new surface biomes and over 10 unique cave types, all while enhancing existing vanilla biomes to feel more alive and varied.
Unlike many other biome mods, Terralith is built to be survival-friendly and aesthetically pleasing. It does not add any new blocks or items (with a few exceptions for custom loot), meaning it can be used as a data pack on servers without requiring players to install a client-side mod. The terrain reaches heights of up to Y=320, with mountains often peaking around Y=290, providing a much more vertical and imposing world than vanilla Minecraft.
