StoneBlock is a modpack series where the world is solid stone. There is no sky and no surface to walk out onto. In the older packs you start in a small room carved out of the stone, and the original does not even give you a tree. StoneBlock 4 starts you in the Garden of Stone, an underground glade where you pick one of five starting islands. From there you mine, craft and work through technology and magic to build your underground base.
How StoneBlock Works
- Stone surrounds you in every direction
- You start with very little and dig out your own space
- Mining provides resources to craft machines
- Technology and magic mods let you generate resources without mining
- Quests guide you through the progression
- The goal is to automate everything from nothing

| Pack | Minecraft | Mod loader | Java |
|---|---|---|---|
| StoneBlock, the original by Sunekaer | 1.12.2 | Forge 14.23.5.2854 | 8 |
| FTB Presents Stoneblock 2 | 1.12.2 | Forge 14.23.5.2860 | 8 |

StoneBlock 4 is the current one, at version 1.22.0 since 22 September 2026. It starts you in the Garden of Stone with a choice of five starting islands. Resource gathering begins with a brush instead of a sieve, and later the Unearther, a villager in a glass cube, refines debris for you. Vaults, Echoes and the World Engine drive the progression. Our FTB StoneBlock 4 server guide covers that pack in detail.
Key Mods
The mod list changes a lot between versions. This is the classic StoneBlock 2 lineup on Minecraft 1.12.2:
| Mod | Purpose |
|---|---|
| Ex Nihilo | Get resources from sifting materials |
| Tinkers' Construct | Custom tools and weapons |
| Thermal Expansion | Machines and automation |
| Applied Energistics 2 | Digital storage |
| Ender IO | Conduits and machines |
| Draconic Evolution | End-game power and tools |
| Mystical Agriculture | Grow any resource as crops |
StoneBlock 3 drops Ex Nihilo, Ender IO, Draconic Evolution and Mystical Agriculture, keeps Tinkers' Construct, Thermal Expansion, Applied Energistics 2 and Mekanism, and brings in Create. StoneBlock 4 builds on Create, Mekanism, Replication, Ars Nouveau, Industrial Foregoing, Occultism and Draconic Evolution, with FTB Quests and FTB Team Bases for progression and co-op.
Server Setup
The FTB packs install the same way:
- Get the server installer for the pack and the exact version your players use. FTB's website has it for Stoneblock 2, 3 and 4. For StoneBlock 4 you can also download the server files from Additional Files on CurseForge: a small zip with a script that fetches FTB's installer for that version.
- Run the installer. It downloads the mods and configs and installs the mod loader: Forge for Stoneblock 2 and 3, NeoForge for StoneBlock 4. It can also download the right Java version for you.
- Use the matching Java: 8 for Stoneblock 2, 17 for StoneBlock 3, 21 for StoneBlock 4.
- Start the server with the run script the installer created and accept the Minecraft EULA.
- For StoneBlock 4, make sure server.properties has
enable-command-block=true. FTB says some structures in the world do not work without it.
The original StoneBlock is not an FTB pack and installs differently. Its last server files, for version 1.0.37 from July 2020, are under Additional Files on CurseForge. Run Install.sh (Install.bat on Windows) once to install Forge, set eula=true in eula.txt, and start the server with LaunchServer.sh. The included server.properties already sets level-type=voidworld, the world type the pack page asks for on servers, so keep that line if you replace the file.
Progression
In StoneBlock 2 the path looks like this:
- Start: Mine stone, craft basic tools
- Early game: Sieve gravel and sand for ores
- Mid game: Build machines to automate sieving
- Late game: Mystical Agriculture farms for every resource
- End game: Draconic Evolution armor and tools
Server Tips
- Most of the world is plain stone, so chunk generation is quick
- Players create their own rooms and tunnels
- Set claim protection so players do not mine into each other
- Resource generation is mostly machine-based, so CPU matters more than disk
- Pre-generating matters less than in overworld packs, because most of the world is uniform stone
How Much RAM StoneBlock Needs
FTB publishes a minimum and a recommended memory figure for each pack version, and its server installer uses the recommended figure as the Java heap. Java needs memory on top of that heap, so we size plans at least 2 GB above it. We have no 10 GB plan, so StoneBlock 4 with its 8 GB heap starts on 12 GB.
| Pack | FTB minimum | FTB recommended, used as the heap | Plan to start on |
|---|---|---|---|
| FTB Presents Stoneblock 2 | 4 GB | 6 GB | MC Diamond, 8 GB, EUR 7.20 per month |
| FTB StoneBlock 3 | 4 GB | 6 GB | MC Diamond, 8 GB, EUR 7.20 per month |
| FTB StoneBlock 4 | 6 GB | 8 GB | MC Special 1, 12 GB, EUR 10.80 per month |
FTB gives no player counts. More people online and bigger factories both need more heap, so move up a plan and raise -Xmx when memory runs short.
The original StoneBlock's CurseForge page asks for at least 5 to 6 GB of RAM for the pack and a decent CPU. Its server files ship with MAX_RAM="4096M" in settings.sh, so raise that to 6144M and start on MC Diamond (8 GB, EUR 7.20 per month) as well. The prices are for our Standard plans; the plan selector on our Minecraft hosting page shows Premium and the price in your region.
Machine-heavy gameplay means CPU is the bottleneck, not disk or network.
