Star Technology modpack Minecraft server

Star Technology is a GregTech CEu Modern skyblock modpack for Minecraft 1.20.1 on Forge. Its CurseForge page calls it a work in progress and "not a beginner-friendly modpack", with a quest book that is updated with every release. You install the server from the Modpacks tab, using the pack's own server files.

Checked against Star Technology 1.20.1 THETA 2 HOTFIX 4 (the latest file, marked beta on CurseForge, with server files dated 6 October 2026) on Forge 47.4.20 and Minecraft 1.20.1, October 2026.

What the pack needs

• Minecraft 1.20.1 with Forge 47.4.20. The server files carry that Forge build in their libraries folder. The panel runs 1.20.1 on Java 17 and picks it for you.
• Memory. The pack's page gives 4 GB as the minimum and 6 GB or more as the recommendation. Your plan sets the RAM, so read how much RAM a Minecraft server needs and check the Minecraft plans before you install.
• Disk space. The server files are a download of about 495 MB and unpack to about 576 MB. The download sits on your plan's disk while it unpacks, so you need room for both.
• The same pack version for players. Players should install Star Technology 1.20.1 THETA 2 HOTFIX 4 from the CurseForge app.

Install the server

Above the search box, press the CurseForge chip and search for Star Technology. Press Install on Star Technology by trulyno. The search also lists separate packs with similar names, such as Star Technology - Hardmode, so check the author. The window should name Forge and Minecraft 1.20.1. If it names another version, press Cancel. The backup, the EULA tick and the hold button are covered in Install a CurseForge modpack.

Once the install finishes, press Start on the Console and wait for For help, type.

The pack's own run.sh asks for a 4 GB heap through user_jvm_args.txt. The panel writes its own start script instead and sizes the heap from your plan's RAM at every start.

First start

The pack's server.properties sets level-type=skyblockbuilder:skyblock, difficulty=peaceful and enable-command-block=false, so the world is a skyblock with hostile mobs off. Open the Config Editor to change Difficulty or Command blocks under Gameplay, save and restart. Leave World type alone: its menu lists only the vanilla types, and the Config Editor writes only the settings you change.

Common problems

• A player cannot join. Check they run the same Star Technology version on Minecraft 1.20.1 with Forge, then compare their mod list with the server's mods folder.
• The server crashes at boot. Find and read a crash report shows how to name the mod at fault. The pack takes bug reports on its GitHub issue tracker.
