Keeping GroundZero up to date

Fortnite updates every few weeks. Usually nothing changes for you. Sometimes an update changes something GroundZero uses, and then your project needs a new version of the Quest SDK.

Your saved island and your published island aren't at risk from any of this. Players keep playing the version you published.

What you'll see​

  • Nothing: this Fortnite version is tested and everything works.
  • "Fortnite 43.10 is new": we're still checking it. Carry on as normal.
  • "Update" on the Quest SDK line: a newer SDK is ready. Press Update, and the panel installs it and rebuilds your Verse.
  • "Fortnite 43.10 changed something GroundZero uses": we know, and a fix is on its way. It will show in the panel.

The panel checks for updates when your project opens. The check sends nothing about you or your island, and if you're offline the panel carries on as normal.

The easiest update: GroundZero Updater​

If we tell you an update is ready, run this before you open your island, and it opens with no errors at all:

  1. Close UEFN.
  2. In your GroundZero download, open the Updater folder and double-click Run GroundZero Updater.
  3. Open your island as usual.

The updater finds every island with GroundZero on your PC, backs up its SDK to Documents\GroundZero\Backups, and updates it. If an island is already up to date, or its add-on is newer than the update, it leaves it alone.

The updater script is signed by ChaosGround Holdings LTD (right-click GroundZero Updater.ps1 > Properties > Digital Signatures to see it). Windows may still ask you to confirm before it runs, and may name an "unknown publisher": that's the small Run GroundZero Updater file that starts it, which Windows can't show a publisher for. Coming: a signed installer that Windows shows as ChaosGround's.

If you open your island first​

You'll see UEFN's Verse errors, and that's fine. Follow the steps in Troubleshooting: don't save, don't delete anything, press Update SDK in the panel, then reopen without saving.

Giving players the update​

Updating changes your project, not your live island. Players get it when you publish your island again, which goes through Fortnite's usual review. Before you publish, run Check setup, and turn off Debug Log on the season device.
