What is FTB StoneBlock 4?
FTB StoneBlock 4 keeps the underground premise and adds generated dungeons and a guided progression. It is the modern StoneBlock, on 1.21.1 and NeoForge.
Skyblock packs start from an empty world and end up as floating factories: light at first, as heavy as a kitchen-sink by the endgame.
Installing FTB StoneBlock 4 on your server
Two sides to prepare: the server, from the panel, and your own game, which needs the same pack in the same version.
Server side
- 1Order a 12 GB Minecraft plan: delivery is instant.
- 2In NexusPanel, open the modpack installer and search for “FTB StoneBlock 4”.
- 3Start the install: the panel fetches the pack and NeoForge for Minecraft 1.21.1, then restarts the server on it.
Player side
Install FTB StoneBlock 4 from the CurseForge app, Prism Launcher or the Modrinth app: they download the pack and NeoForge for you. Then add your server address, shown in NexusPanel.
Versions must match exactly between server and client: a single modpack version apart is enough for the connection to be refused.
How much RAM for a FTB StoneBlock 4 server?
We recommend the 12 GB tier for FTB StoneBlock 4, and it is the one priced above. A modpack uses memory per loaded mod before it uses any per player: the pack sets the tier, the number of connected players only fine-tunes it.
You can change tier at any time from your client area, prorated and without losing your progress.
Configure a 12 GB serverFrequently asked questions
How much RAM does a FTB StoneBlock 4 server need?
The 12 GB tier is the one we recommend for FTB StoneBlock 4. Below it the server still boots, but world loading times and TPS degrade as soon as several players explore at the same time.
Which Minecraft version and which mod loader?
FTB StoneBlock 4 runs on NeoForge for Minecraft 1.21.1. The panel installs both together: no server jar to upload, no NeoForge to configure.
How do I install FTB StoneBlock 4 on my server?
From NexusPanel: open the modpack installer, search for “FTB StoneBlock 4”, pick the version and start. The server restarts on the pack. No FTP access is needed, although it stays available.
How many players on a FTB StoneBlock 4 server?
Our Minecraft plans are sold by RAM, not by slot count: memory is what sets the practical limit. The 12 GB tier suits a group of friends; beyond about ten players exploring at the same time, move up one tier.
Can I switch modpacks later?
Yes, as often as you like: the panel's installer offers more than 10,000 CurseForge modpacks and 9 distributions (Paper, Forge, NeoForge, Fabric, Mohist…). Back up your world before switching packs — a world is not compatible from one modpack to another.
