Adding Biomes O' Plenty to Your Minecraft Server

Vanilla Minecraft already ships with a respectable variety of biomes, which is part of why no two worlds ever feel exactly the same. Even so, there comes a point where you've seen enough birch forests for one lifetime. Biomes O' Plenty steps in with dozens of fresh landscapes for both the Overworld and the Nether, complete with new trees, plants, blocks, and ambient touches that make exploration feel new again.

This guide walks through downloading the mod, installing it on your client, and getting it running on a server.

What Biomes O' Plenty Actually Does

Biomes O' Plenty rewrites a significant chunk of world generation. Created by Forstride and TheAdubbz, with mascot art by GlitchfiendMods, the mod injects more than fifty unique biomes into your save. Because it touches generation so heavily, expect higher CPU and memory usage than a vanilla world, especially during chunk loading. Low end machines may struggle, and on a server you'll likely want to tweak a few performance settings.

With well over 50 million downloads, it sits among the most popular world generation mods in modded Minecraft. Once you load a fresh save with it active, the reputation makes sense.

Step 1: Install Forge

Biomes O' Plenty is a Forge mod, so Forge has to be in place before anything else.

1. Download the Forge installer that matches the Minecraft version you plan to play.
2. Run the jar file and pick Install Client when the installer pops up.
3. Launch (or relaunch) the Minecraft launcher and switch the installation profile to Forge if it doesn't change on its own.

Step 2: Download the Mod

With Forge ready, grab the mod itself from CurseForge.

1. Open the Biomes O' Plenty page on CurseForge and click the Files tab.
2. Find the release that matches your Minecraft and Forge version.
3. Hit Download and save the .jar somewhere easy to find.
4. If you're on Minecraft 1.18 or newer, also download TerraBlender. Biomes O' Plenty depends on it from that version onward, and the server will refuse to start without it.

Step 3: Install the Mod on the Client

Time to drop the file where Minecraft can find it.

1. Press the Windows key and type `%appdata%` into the search bar.
2. Open the .minecraft folder, then open mods.
3. Drop the Biomes O' Plenty .jar (and TerraBlender, if you grabbed it) into the mods folder.
4. Close everything and relaunch Minecraft with the Forge profile.

Step 4: Install the Mod on the Server

For multiplayer, the same .jar has to live on the server side.

1. Log in to your HolyHosting control panel.
2. Stop the server. Mods should never be added on a running instance.
3. Once the server shows as offline, open your FTP client and sign in.
4. Navigate to the mods directory.
5. Use the upload option and drop in the Biomes O' Plenty .jar (plus TerraBlender for 1.18+).

When the upload reports 100% 1/1 files, head back to the panel and start the server.

Step 5: Switch the World Type

Versions 1.18 and above pick up the mod's biomes automatically, so no extra configuration is needed there. Older versions need a manual switch.

For Minecraft 1.15 through 1.17:

1. Stop the server.
2. Open the configuration files section of your panel.
3. Open the server.properties file.
4. Set `level-type` to `biomesoplenty`.

For Minecraft 1.12.2 and below:

1. Stop the server.
2. Open the configuration files section of your panel.
3. Open the server.properties file.
4. Set `level-type` to `BIOMESOP`.

Remember to delete or rename the existing world folder if you want the new generation to take effect. Existing chunks stay vanilla, so only freshly generated terrain will pull from the mod.

A Quick Look at the Scenery

Gameplay does not change in any noticeable way. You still mine, craft, build, and occasionally lose your kit to a creeper. The difference is what's on the horizon. The new wood types end up being a personal highlight, since they slot into vanilla builds without feeling out of place.

Common Issues

Server crashes on startup. Usually a duplicate mod, a missing dependency, or a version mismatch. Biomes O' Plenty itself has no dependencies on pre-1.18 versions, but TerraBlender is required from 1.18 onward.

Server stuck loading. When the mod list changes, Forge sometimes wants a manual confirmation. Watch the console for a Missing Mod IDs message and type `/fml confirm` to push past it.

Duplicate mods. The console prints a clear Duplicate Mods warning with the offender named. Open FTP, navigate to the mods folder, and delete the extra copy.

Missing dependency. Errors like `The mod NEI requires mod [JEI] to be available` tell you exactly what is missing. Download the named dependency and place it in the mods folder.

Wrong mod version. Forge logs a clear notice if a jar targets a different version, for example `File jei_1.12.2-4.15.0.268.jar is for an older version of Forge and cannot be loaded`. Replace it with a build that matches the Forge release you're running.

Wrapping Up

That's the whole setup. Biomes O' Plenty is not a complex mod to install, but the amount of content it brings is huge. Pair it with a couple of light visual mods and you have a solid excuse to start a brand new save. Have fun exploring.
