Quick answer

Which Oneblock Ultimate release should I use?

Updated 22 days ago
Latest stable file Oneblock Ultimate 1.2.0
Game version 1.21.1
Loader NeoForge 21.1.241

Oneblock Ultimate 1.2.0 is a complete pack release for 1.21.1 with NeoForge 21.1.241. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. For this loader, use Java 21. 78 mods in this pack file.

Pack setup

How should I set up Oneblock Ultimate for players and a server?

Use Oneblock Ultimate 1.2.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Oneblock Ultimate 1.2.0
Dedicated server setup Match Oneblock Ultimate 1.2.0
Pack loader NeoForge 21.1.241
Java version Java 21

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 78
Client only 28
Server only 6
Not labelled 44

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Oneblock Ultimate?

Oneblock Ultimate 1.2.0. Change the pack release and its contents or setup may change too.

78 mods in this pack file

The selected pack release is Oneblock Ultimate 1.2.0. That file is for Minecraft 1.21.1 with NeoForge 21.1.241. This NeoForge setup needs Java 21. It contains 78 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

About this project

What kind of pack is Oneblock Ultimate?

Oneblock Ultimate

A modern recreation of the classic Oneblock experience — rebuilt for NeoForge 1.21.1.

Oneblock Ultimate is a polished, stable, and flexible Oneblock modpack, recreated entirely from scratch. The original from TL Mods was never republished, so this is a fresh take — redesigned for modern systems and built to run any Oneblock map you want to play.

Getting started

  1. Install the pack with the Modrinth app
  2. On first launch, a FancyMenu prompt offers recommended Oneblock maps — pick one and you're in
  3. Later, swap in any map you like. Classic, modded, themed, or challenge-based — it all works

The pack doesn't bundle maps on purpose: we can't redistribute other people's work
without their consent, and that respect is exactly what sets us apart. Oneblock
Ultimate is the only pack built around that principle — and the in-game helper
makes setting up your map effortless instead of a chore.
