Tectonic Mod is a worldgen datapack and mod that adds more interesting terrain features, improved vegetation and 25+ new biomes and biome variants. This wiki aims to provide more information on the features of this pack as well as other information related to Tectonic (including how to install it and which packs are compatible with it).

Features:

Mountain Ranges

• Mountains now extend for upwards of thousands of blocks long and hundreds of blocks wide. They can frequently reach heights above y=200.
• Mountains will no longer generate near inland or have “saddle valleys” around them.

Oceanside Cliffs

• Cliffs generate where terrain would be generated a steep drop from coastal terrain to ocean.
• Cliffs tend to form large overhangs.
• A special variant of cliffs, the Icy Cliffs, has large ice stalagmites and stalagtites underneath overhangs.

Underground Rivers

• Underground Rivers generate when a river is unable to generate due to terrain being too high (such as where a mountain range is)
• The rivers may stretch for thousands of blocks and may have divergent paths in them.
• There are currently 6 underground river biomes for you to find.

• Icy Cliffs
  Ice stalagmites and stalagtites generator under the overhangs in this biome. The top layers of the biome are snow blocks instead of stone.
