One Block ModPack
A lightweight OneBlock-based modpack that lets you start on a single regenerating block and build your world from nothing. Includes extra performance mods for smoother gameplay and better stability.
Quick answer
Which One Block ModPack release matches Fabric?
One Block ModPack 1.0.0 is a complete pack release for 1.21.10 with Fabric 0.18.1. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 12 mods in this pack file.
Pack setup
How should I set up One Block ModPack for players and a server?
Use One Block ModPack 1.0.0 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.
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.
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 One Block ModPack?
One Block ModPack 1.0.0 on Fabric. The pack contents and setup notes below stay tied to that release.
The selected pack release is One Block ModPack 1.0.0. That file is for Minecraft 1.21.10 with Fabric 0.18.1. It contains 12 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 One Block ModPack?

This modpack delivers a fully enhanced OneBlock experience, combining the depth and progression of the original OneBlock mod with a collection of performance-boosting addons for smooth, stable gameplay. Begin your journey stranded in the void on a tiny floating island, where a single regenerating block becomes your only source of materials. With every block you break, new resources appear — from simple dirt and wood to rare blocks from the Nether and End. As you progress, biome cycles, surprise events, friendly mobs, and evolving monster waves keep the world feeling alive and unpredictable.
Explore more than 40 biomes through the OneBlock’s cycling system, unlock entire new material pools by reaching the Nether and End, and survive increasingly challenging encounters designed to scale with your growth. Whether you're gathering essential early-game materials or facing chaotic late-game waves, every block break shapes your story.
To ensure a smooth experience, this modpack includes a curated set of performance mods, improving FPS, reducing lag spikes, and enhancing overall client and server stability. Even players with low-end PCs can enjoy a seamless adventure thanks to optimizations that work quietly in the background without affecting gameplay.
The modpack supports both singleplayer and multiplayer. In multiplayer mode, each player can generate their own independent OneBlock island, spaced safely apart so everyone can progress at their own pace. Optional datapacks allow you to customize the experience even further — from void dimensions to hardcore no-island starts.
With its blend of survival, randomness, progression, and optimization, this modpack offers a clean, polished, and replayable OneBlock journey for all kinds of players. Build, fight, explore, automate, and expand — your entire world grows from one single block.
