What is it?
What is the Biomes O Plenty Mod?
Biomes O' Plenty is a long-running biome mod for Minecraft: Java Edition. It adds a large set of new biomes with a vanilla-like style, so they sit naturally beside the game's own terrain.
The new biomes arrive with the things that make them recognisable: new trees and wood types, flowers, plants and building blocks. On Minecraft 1.18 and newer the mod uses the TerraBlender library to blend its biomes into normal world generation, so no special world type is required.

Features
What changes in your world
Five areas you will notice as soon as you explore a freshly generated chunk.
New trees and wood
Biome-specific trees add logs and planks in colours vanilla does not offer.
Plants and flowers
Ground cover and flowers make every biome recognisable at a glance, from pastures to bogs.
Nether and End additions
New biomes also generate in the Nether and the End, so late-game travel gets fresh scenery too. They appear in newly generated chunks of each dimension.
Designed to share a world with other biome mods
Modern versions rely on TerraBlender, a library made so several biome mods can add content to the same world. Pack makers can adjust behaviour through the config/biomesoplenty folder.
How it works
From files to new biomes in four connected steps
Each node depends on the one before it. If the chain is complete, new chunks generate with the mod's biomes.
-
1Input
Choose version and loader
One Minecraft version, and a loader it supports: Forge, NeoForge or Fabric.
-
2Dependencies
Add the libraries
TerraBlender on 1.18+, GlitchCore where required, Fabric API on Fabric.
-
3Load
Start the loader profile
The loader reads the mods folder and registers the new biomes and blocks.
-
4Output
Generate new chunks
Create a world or explore unvisited land to see the biomes appear.
Use cases
Who it is for
Different players install the same mod for quite different reasons.
-
Survival explorers
When vanilla terrain feels familiar, new biomes give long journeys a purpose again. Every direction can lead somewhere you have not seen.
-
Builders
Extra wood types and plants widen the block palette for houses, gardens and landscaping.
-
Modpack makers
A widely used biome mod that works alongside other TerraBlender-based mods, with a config folder for tuning.
-
Server owners
From 1.18 onward, no server.properties change is needed. Install the same files on server and clients.
-
Screenshot creators
Distinct landscapes and colour palettes make cinematic worlds easier to compose.
-
Nether and End travellers
New biomes in other dimensions make late-game trips less repetitive.

Installation
Setting up Biomes O' Plenty
The same sequence works for Forge, NeoForge and Fabric. Only the files you pick change.
Need more detail? The full installation walkthrough covers each step, including third-party launchers.
-
Install the loader
Run the Forge, NeoForge or Fabric installer for your Minecraft version and launch its profile once.
-
Collect matching files
The mod jar plus TerraBlender (1.18+), GlitchCore (1.20.4+, or 1.20.1 from 19.0.0.91) and Fabric API on Fabric.
-
Copy the jars into mods
Place them directly in the mods folder, not in sub-folders and not still zipped.
-
Launch and create a world
On 1.18+ any new world works. On 1.17 and older, choose the Biomes O' Plenty world type.

Troubleshooting
Common issues and their fixes
Most problems are version mismatches, not bugs. More detail in the crash fixes guide.
Error names TerraBlender or GlitchCore
A required library is missing or for the wrong version. Download it for the same Minecraft version and loader.
Mod ignored or marked incompatible
The jar targets another loader or Minecraft version. Replace it with the file tagged for your exact setup.
Game loads, but no new biomes
You are in chunks generated before the mod was added. Explore far away or make a new world; on 1.17 and older use the Biomes O' Plenty world type.
"Unsupported class file version"
Wrong Java runtime. 1.12.2 uses Java 8, 1.18 to 1.20.4 use Java 17, and 1.20.5+ need Java 21 or newer.
The downloaded ZIP does nothing in mods
The GitHub archive is source code. Use a built release jar from the developers, or build the project yourself with Gradle.
FAQ
Biomes O Plenty Mod questions
Twenty answers in two categories. Arrow keys move between questions.
Downloading and installing
10 questionsBiomes O' Plenty is a Minecraft: Java Edition mod developed by Glitchfiend. It adds a large set of new biomes to the Overworld, Nether and End, along with new plants, flowers, trees and building blocks.
Yes. The Java Edition mod is distributed by its developers without charge on their project pages. The separate Bedrock Add-On is sold through the Minecraft Marketplace, where pricing is set by the Marketplace.
It downloads a ZIP archive of the 26.3 branch of the Glitchfiend/BiomesOPlenty repository on GitHub. That archive contains source code, not a ready-to-play jar. To play, most people use a built release file for their Minecraft version and loader.
It depends on your Minecraft version. Recent versions are published for Forge, NeoForge and Fabric, while legacy lines such as 1.12.2 use Forge. Always pick the file whose loader tag matches the loader you installed.
TerraBlender is required for Minecraft 1.18 and newer. GlitchCore is required for 1.20.4 and newer, and for 1.20.1 from mod version 19.0.0.91. The Fabric version also needs Fabric API.
On Windows it is %appdata%\.minecraft\mods, on macOS ~/Library/Application Support/minecraft/mods and on Linux ~/.minecraft/mods. Launch your loader profile once and the folder is created if it is missing.
On 1.18 and newer, yes, but only chunks generated after installing the mod can contain its biomes. Areas you already explored stay the same. On 1.17 and older you need a new world created with the Biomes O' Plenty world type. Back up your world first.
Put the same mod and library files on the server and on every client. From 1.18 onward no server.properties change is needed. For 1.15 to 1.17 set level-type to biomesoplenty, and for 1.12.2 and older set it to BIOMESOP, then generate a new world.
Yes. The developers publish built releases on mod platforms including Modrinth and CurseForge, with each file tagged by Minecraft version and loader.
Use files uploaded by the developers on their own project pages or the GitHub repository. Avoid sites that hide the file behind redirect pages, offer .exe installers, or ask you to disable antivirus software. A real mod file is a .jar you copy into a folder.
Versions, gameplay and compatibility
10 questionsThe jar mod only works on Java Edition. For Bedrock, the project page points to a separate Bedrock Add-On on the Minecraft Marketplace. Java files cannot be installed on Bedrock, and Bedrock add-ons cannot be installed on Java.
Yes, for recent Minecraft versions the developers publish Fabric builds alongside Forge and NeoForge builds. The Fabric build needs Fabric API, TerraBlender for Fabric and, on newer versions, GlitchCore.
Legacy 1.12.2 builds exist and run on Forge with Java 8. On that version the new biomes appear only in worlds created with the Biomes O' Plenty world type, and servers need level-type=BIOMESOP.
Yes, 1.20.1 is a popular version for the mod. You need TerraBlender for 1.20.1, and GlitchCore as well if your mod build is 19.0.0.91 or newer. Check the release page for the loaders available for the build you choose.
The mod adds biomes to the Overworld, the Nether and the End. Each only appears in newly generated chunks of that dimension.
Alongside the biomes it adds new plants, flowers, trees and building blocks, including new wood types that builders often use for their colour palettes.
With cheats on, use /locate biome biomesoplenty: followed by the biome ID on 1.19 and newer, or /locatebiome on 1.16 to 1.18. Press Tab after the namespace to see every available biome ID.
TerraBlender exists so that several biome mods can add biomes to the same world in a compatible way. Combinations still vary, so add mods one at a time and test in a fresh world before committing to a long-term save.
The Modrinth listing allows it in Modrinth-hosted modpacks if you do not rehost the mod, only use builds uploaded by the developers, do not sell the pack or access to the mod, and follow the license for your version.
Generating brand-new chunks with dense forests takes more work, especially while exploring quickly. Lower render distance, sensible memory allocation and pre-generating chunks on servers keep things smooth.
