Tectonic Data Pack (1.21.11, 1.20.1) – It’s time to Explore a New Generation of Terrain








Tectonic Data Pack is a major data pack that significantly overhauls the game’s overworld generation. Here, you will see tall mountain ranges, underground rivers stretching forward for thousands of blocks, and interesting landscapes that make exploring the world much more exciting – all without adding any new blocks.
