Tellus

World Generation & Terrain

• Added support for oceans using GEBCO 2026 bathymetry data.
• Improved inland water generation so it works better in areas where terrain is unstable, including with fast LODs.
• Added Thin Shell Terrain, which disables underground terrain and keeps only the surface.
  • This feature is currently WIP.
• Deepslate is no longer used for mountains, as mountainous terrain is being reworked.
• Fixed snow in mountains showing dirt underneath the snow when using fast LODs.

Buildings, Roads & Structures

• Improved buildings and added more road details and elements thanks to the Arnis project: https://arnismc.com

  • Distant Horizons LODs may not perfectly represent some of these new buildings yet.

• Added an option for areas where ESA data shows built-up features such as buildings, roads, and infrastructure to use a Minecraft biome from the Köppen/ESA classification instead of only stone and gravel.

• Villages no longer spawn in the middle of water bodies, such as lakes.

Biomes

• Made biome adjustments for better biome selection based on Köppen climate data.

• Oceans now use NOAA OISST v2.1 as the temperature source for biome classification.

  • Inland biomes still use Köppen/ESA data for classification.

• Added a Random Biomes option with a percentage slider.

  • This is intended for a more Minecraft-like survival experience while still using real-world terrain.
  • This mode still uses Köppen and ESA data, but mixes in random Minecraft biomes.

• Added more Minecraft biomes:

  • warm_ocean
  • lukewarm_ocean
  • cold_ocean
  • frozen_ocean
  • deep_ocean
  • deep_lukewarm_ocean
  • deep_cold_ocean
  • deep_frozen_ocean
  • sunflower_plains
  • flower_forest

• New Sulfur Caves are planned.

UI & Localization

• Added Japanese translation.
  • Translations made with AI, so hopefully the translations are accurate 😅
• The Set Spawnpoint map search box now shows suggestions using Minecraft’s selected language.

Fixes & Backend Improvements

• Fixed some trees showing a gray palette instead of their proper color when using fast LODs.
• Fixed issues across cache handling, terrain preview, and other backend systems.

Known Issues

• Some coastlines may still show broken or unusual terrain elevation.
  • This is mainly caused by resolution differences between inland and ocean terrain.
• Ocean fast LODs may show strange underwater elevation near coastlines.
• Fast LODs may show water elevation inconsistencies compared to full chunks.
