FTB Sky Adventures modpack Minecraft server

FTB Sky Adventures is a large skyblock pack for Minecraft 1.12.2 on Forge, mixing tech and magic around the FTB Quests questing system. Its page says multiplayer support is built into the server files, with each team on its own island. The Modpacks tab installs the server from Feed The Beast's own source.

Checked against FTB Sky Adventures 1.5.1 on Forge 14.23.5.2860 and Minecraft 1.12.2, October 2026.

What the pack needs

• Minecraft 1.12.2, Forge 14.23.5.2860 and Java 8. These are the targets Feed The Beast lists for 1.5.1, the newest release. The panel picks Java 8 for any Minecraft version below 1.17.
• 4 GB of RAM. The pack's page lists 4 GB as both the minimum and the recommended amount. Compare that with your plan using how much RAM a Minecraft server needs and the Minecraft plans.
• The same version for players. They install FTB Sky Adventures 1.5.1 from the FTB App, Feed The Beast's launcher.

Install from the Feed The Beast source

On the Modpacks tab, press the Feed The Beast chip and search for Sky Adventures. Searches need at least three letters. If there is no Feed The Beast button, that source is not available on your account yet, and this route does not apply until it is. Press Install on FTB Sky Adventures. The version dropdown lists 1.5.1, 1.5.0 and 1.4.0; leave it on Newest that fits your server. For a fresh start leave Keep my world, settings and player lists unticked. If the window shows a note about your world in place of that tickbox, your world was saved by a newer Minecraft than this pack can open, so it is not kept, and your current world goes into the backup. You hold Install and reinstall for three seconds. The install takes under a minute, and the console ends it with "Pack installed. Launch: -jar forge-1.12.2-14.23.5.2860.jar nogui". The rest of the window is in Install an FTB modpack. Then press Start on the Console and wait for For help, type.

CurseForge's newest Sky Adventures file, 1.5.0, has no server pack attached. This guide uses the Feed The Beast source, which provides a server installer.

How teams and islands work

The pack's page says players join an FTB Utilities team, or create their own, and are teleported to a new island with their spawn point set. Joining an existing team puts you on that team's island. The page adds that quest progress and inventory belong to the island and team, and when a player starts a new island or joins another team, their quest progress is reset and their inventory is deleted. The page also says there is no limit on team or island creation by default. Tell your players this before they switch teams.

For admins, the page says each island is centered in one region file, which makes troubleshooting and deleting old islands easy. Take a backup before you delete anything in File Manager.

Common problems

• A player cannot join. Check they run FTB Sky Adventures 1.5.1 on Minecraft 1.12.2. Join a modded server from your launcher has the steps.
• A player lost their inventory. The pack's page says it deletes the inventory when someone starts a new island or changes team. Restore from Backups if it was a mistake: Create and restore backups.
• The server crashes at boot. Find and read a crash report shows how to name the mod at fault.
