Epic Terrain Compatible

by wonderful_Ai_Chen

Epic Terrain Compatible rewrites vanilla terrain generation through a datapack, adding eroded surfaces, alpine peaks, rivers and new coastlines to worlds that players explore.

What it does

The mod changes how the world surface is shaped. Its terrain is smoother and resembles eroded land, with cliffs along the sea and tall alpine peaks in mountainous areas. Terrain can also be generated in the manner of continental plates, so landmasses form broader structures than the default generator produces.

Rivers come in small and large sizes and wind through several biomes, and underground rivers are included. Underground terrain can contain magma rivers. Coastlines take several forms, from carved bays to narrow channels and offshore landforms.

Because the terrain follows a realistic scale, worlds can be very large, and the author recommends a separate preview mod for inspecting maps before exploring them. The mod is distributed as a datapack for Fabric, Forge, NeoForge and Quilt, covering game versions 1.19 – 1.21.11. It requires Cloth Config API and WorldgenFeatureFix, and Abundant Vegetation is optional. Server owners install it, and players can join with or without it. The code is under All rights reserved, so it is not open source.

Key features

  1. Eroded terrain surfaces

    Terrain is smoother and shaped like eroded land, replacing the flatter default surface.

  2. Alpine peaks and cliffs

    Mountain areas gain tall alpine peaks, and cliffs appear along the coast where land meets the sea.

  3. Rivers across biomes

    Small and large rivers wind through several biomes, and underground rivers run beneath the surface.

  4. Varied coastlines

    Erosion and indentation coasts, straits, islands, peninsulas and Mediterranean seas are generated.

  5. Underground magma rivers

    Underground terrain is added, and it includes rivers of magma below the surface.

What the author says

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. Now, this datapack can do just that, as it rewrites the terrain for the game. You can now see the mountains in the game!
