This package was written by me through the datapack exercise. Because I was tired of vanilla terrain and I always wanted a realistic terrain that was efficient, I set out to refactor vanilla terrain.
📖What's this datapack?
In the original, although the terrain of the higher version has been overhauled, it is still not spectacular enough, and it does not feel like it is surrounded by mountains.
Now, this datapack can do just that, as it rewrites the terrain for the game. You can now see the mountains in the game!
The support issue for 1.21.8 has been resolved.
This datapack adds real plains, real alpine peaks to Minecraft.
💡Features:
- Smooth surface.
- Resembles eroded terrain.
- Spectacular alpine peaks.
- Terrain can now generate like continental plates.
- There are cliffs by the sea.
- Added small and large rivers that shuttle through various biomes.
- Added the function of underground rivers.
- New coastlines: can form erosion and indentation coasts, Mediterranean Seas, straits, islands, peninsulas.
- Added underground terrain and spawned magma rivers.
Because with reality as a reference, the map size is too large, and the ocean can have 10,000 tiles. It is recommended to use the World Preview mod for map preview.

Note
- This is a https://modrinth.com/mod/terrablendermod biome-compatible version.
- The module version of the data pack is not compatible with Terralith. If needed, please use the Epic Terrain data pack along with the Terralith data pack, and place the Epic Terrain data pack at the top.
- If there is a problem with the river, please pin Epic Terrain at the top.
This data package supports custom functions.
- The modified document has been placed in the zip data package, you can open and edit it yourself (I'm sorry it's only in Chinese, I don't speak much English, so please translate it yourself).
