Layers ( world generation )
by bonsai.rio99
Layers changes how Minecraft's terrain is generated, reshaping mountains and valleys and adding fallen trees and rocks to the world.
What it does
The basic world generation of mountains, valleys and similar terrain is replaced by the mod's own generation tool, which adds new structures such as fallen trees and rocks. Because the mod alters the base terrain, it can produce very large mountains that place more strain on some machines, so the author asks players to consider their hardware before starting a world with it.
New updates keep arriving and the author plans to add more biomes and generation features over time. Layers is a server-side only mod released under All rights reserved, so it is not open source. The current files target 1.20.1 for Forge, with the 1.0.0 build dated 2025-06-18 as the only release so far.
Key features
Reshaped terrain
The generation of mountains and valleys is changed, so new worlds differ noticeably from vanilla terrain.
Fallen trees and rocks
New structures such as fallen trees and rocks are added to the landscape during world generation.
Larger mountains
Terrain can form very large mountains, which increases the load on weaker machines and may cause lag.
Ongoing updates
The author has said that new biomes and generation features will be added in future updates.

Use cases
Fresh survival worlds
A new world created with the mod gets the altered terrain and structures from the first chunk onward.
Who it’s for: Players and server owners who want a different terrain style on a Forge server running Minecraft 1.20.1, and who have hardware able to handle the larger mountains the mod can generate.
How it compares
No Stronghold is a Fabric, Forge and Quilt mod for 1.20 – 1.20.1 that is server required with the client optional, and it is released under the MIT License. Realistic Oceans is server-side only, under All rights reserved, and works on Fabric, Forge and NeoForge for 1.20.1 – 1.21.11, so it covers a wider version span than Layers.
