Epic Terrain
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.

Epic Terrain Compatible:https://modrinth.com/datapack/epic-terrain_compatible
Epic Terrain is an experimental product for technical experimentation, so compatibility is not considered.
Currently, there are bugs in MC1.21 and above versions 1.4a~b. I have found the reason; I used minecraft:lake, but it has bugs in 1.21. Fortunately, someone has already attempted to fix it. https://modrinth.com/mod/worldgenfeaturefix
📖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!

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.
- Brand new coastlines: Can form eroded inlets, seas, straits, islands, and peninsulas.
- A new river system with large rivers and small rivers, with a drop function, and a source.
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
- [https://modrinth.com/mod/terrablender cannot be used, as it will disable surface functionality. Such as: rivers]
- Because the biome distribution has been reset, it is almost incompatible with modules that increase biomes, and mods that modify the original version can be used
- Theoretically 1.19 should be supported, but 1.19 doesn't support custom biomes, so I shouldn't update 1.19.
