Epic Terrain

by wonderful_Ai_Chen

Epic Terrain is a server-side world generation datapack that replaces vanilla terrain with eroded surfaces, alpine peaks, new coastlines and a river system.

FabricForgeNeoForgeQuiltServer required, client optionalMIT LicenseOpen source1.19 – 1.21.4

What it does

The datapack reworks how terrain is generated: surfaces are smoother and resemble eroded land, high alpine peaks rise in mountain areas, and terrain can form in continent-like shapes. Coastlines are reshaped into inlets, seas, straits, islands and peninsulas, and a new river network adds rivers of two sizes, with a drop function and a defined source.

Because the map is built from a realistic scale reference, the ocean can span around 10,000 tiles, so the author suggests using a separate map preview tool before exploring. Epic Terrain is described as an experimental technical project, and compatibility with other mods is not considered. Biome distribution has been reset, so it is nearly incompatible with mods that add biomes, while mods that change the original game can still be used.

Epic Terrain runs on the server; players join without installing it, though they may add it. Files target 1.19 – 1.21.4 across Fabric, Forge, NeoForge and Quilt, with a data pack build as well. The code is under the MIT License and is open source. Arboria: Biome Enhancement is an optional dependency.

Key features

  1. Eroded surface shapes

    Terrain surfaces are smoothed and shaped to resemble eroded landscapes rather than the flat patterns of vanilla generation.

  2. Alpine peaks

    High mountain peaks generate in mountain regions, adding tall alpine terrain to the world.

  3. Continent-like terrain

    Land masses can generate in shapes similar to continental plates, giving broader landform patterns.

  4. Reshaped coastlines

    Coasts take on eroded inlets, open seas, narrow passages, islands and peninsulas instead of vanilla shorelines.

  5. River network

    Large and small rivers join a new river system with a drop function and a defined source.

Use cases

Realistic exploration worlds

Who it’s for: Server owners and players who want a datapack with eroded terrain, mountains and new river systems, and who accept that the project is experimental and not tested for compatibility.

Questions

Does Epic Terrain need to be installed on the client?

No. Only the server needs the datapack, and players can join a server running it without installing anything.

Which loaders does Epic Terrain support?

Files are published for Fabric, Forge, NeoForge and Quilt, and a data pack build is also available.

Is Epic Terrain compatible with biome mods?

Biome distribution has been reset, so the datapack is nearly incompatible with mods that add biomes. Mods that alter the original game can still be used.

Why does the map need a preview tool?

The ocean can span about 10,000 tiles, so the author suggests a separate map preview tool to see the layout first.

What the author says

This pack is a test item for me to practice datapack. Because I was tired of the vanilla terrain and I always wanted an efficient realistic terrain, I started refactoring the vanilla terrain. Epic Terrain is an experimental product for technical experimentation, so compatibility is not considered.
