|---|---|
| Loaders | Fabric, Forge, NeoForge, Quilt |

Vanilla One Block is a skyblock-style challenge for Java. You start on a single grass block at the bottom of a void world and build everything from there. It ships as a plain data pack and as a mod for Fabric, Forge, NeoForge and Quilt, so the same world generation works with or without a loader. It is required on the server and optional for players who join.
Loaders and versions
- Fabric, Forge and Quilt: Minecraft 1.19.4 to 26.2. The newest build needs no dependencies, optionally Disable Custom Worlds Advice and Sky Void Additions; some builds for 1.19.4 to 1.20.4 require Disable Custom Worlds Advice.
- NeoForge: Minecraft 1.21 to 26.2. The newest build needs no dependencies, optionally Disable Custom Worlds Advice and Sky Void Additions.
Installation
- Mod route: put the mod file for your loader in the mods folder and launch with that loader's profile. The steps are covered in how to install mods on Java.
What the world generates
The grass block sits at Y=-64 in a Snowy Taiga biome, and the world spawn moves to the block's location at Y=0, so mobs can spawn on it. Everything else is void, but the structure bounding boxes that matter in skyblock generate at the same coordinates as a normal world with the same seed. Ancient Cities, Ocean Monuments, Pillager Outposts, Witch Huts, Nether Fortresses and Trial Chambers keep the same bounding boxes. Guardian and witch farms can be built as normal.
Only a few blocks appear outside the starter island: End portals and sculk sensors. Strongholds produce just an entrance portal with some filled eyes, and each portal has a single block of lava beneath it. In the End, the obsidian pillars and exit portal generate as normal, and an end gateway creates a small island.
The initial grind
Until a player obtains an iron shovel, the pack bends the rules to speed up the opening.
- Over 80% of hostile mobs are zombies, and every zombie carries an iron shovel.
- Once the shovel is obtained, it rains continuously until 23 snow blocks are placed.
BPR02's SkyBlock Collection also offers other void presets, including ones where the stronghold generates with a lava pit or the entire portal room beneath the end portal.
Questions about Vanilla One Block.
3 questions
How do I create a vanilla OneBlock world?
The Vanilla One Block data pack generates a void world with a single grass block at the bottom of the world in a Snowy Taiga biome, and the world spawn moves to that block at Y=0. Some seeds fail, because the locator needs a snowy taiga within 2000 blocks.
Does Vanilla One Block work on multiplayer servers?
Yes. The pack is required on the server and optional for players who join, so they do not need to install it. A mod build needs its matching loader, Fabric, Forge, NeoForge or Quilt. The newest release lists no required dependencies.
Which loaders does Vanilla One Block support?
The mod supports Fabric, Forge, NeoForge and Quilt, and a plain data pack covers setups without a loader. The newest release needs no dependencies. Disable Custom Worlds Advice and Sky Void Additions are optional extras.
