Terralith¶
Terralith (v2.5.14) by Starmute / Stardust Labs adds 95+ new biomes and completely overhauls Overworld terrain generation. It was featured in the official Minecraft: Java & Bedrock Edition trailer.
What It Changes¶
- 84 new surface biomes and 11 new cave biomes
- Mountains reaching up to Y=290
- Smooth terrain transitions using slabs and layered snow
- Desert dunes, mesa arches, dramatic canyons, and cliff overhangs
- 25+ custom structures including Fortified Villages, Mage Towers, and Spires
- All built with vanilla blocks only — no new block types
Ore Distribution
