Fortnite: Creative Dev Tracker

We are aware of an issue where new installations of UEFN will not open and will close immediately. We are investigating and will let you know when we have more information.

Our March “Ask Epic” is almost upon us, and this time our team of experts will be answering your questions about Verse. A lot of news came out of the State of Unreal at GDC 2024, and we’ll be taking your questions about Verse Persistence, Scene Graph (which will enable you to dynamically manipulate almost every object in your game, alongside a new prefab system), and more.

We're aware of an issue with the NPC Spawner failing to spawn an NPC if they have been published before 29.01 is released. We are investigating the problem and working on a fix, but in the meantime, you can use this workaround.

1. Select all NPC Character Definition assets in the content browser (you can use the filter to do this easily).
2. Right click on the assets
3. Choose Save to force resave all the assets
4. Re-publish your UEFN project.

After that the NPC Spawner device should now work properly and spawn the NPCs in your published experience.

Known Issue:

LEGO Elements and other LEGO brand assets are now available in Fortnite Creative and UEFN.

If you’re a member of the Island Creator Program, and sign the additional terms and conditions, you can now start building your own LEGO Islands with LEGO Elements such as brand templates, props, consumables, items, and more. You’ll also find a choice of four template islands to help you get up and running — three featuring prebuilt biomes, and one blank canvas that lets you start from scratch.

Did we mention your island’s players will be in the LEGO Style of Fortnite Outfits? It’s a Minifigure party!

You can now import your MetaHuman into UEFN to use on your islands as an NPC using the NPC Spawner device. Facial animation created using MetaHuman Animator can also be applied to any MetaHuman or any Fortnite character in UEFN.

MetaHuman Creator enables you to produce realistic digital humans that are fully rigged and ready to use in UEFN. MetaHuman Animator will turn footage captured from an iPhone or stereo head-mounted camera into facial animation for your MetaHuman.

With Verse Persistence, you can give your players the ability to save their progress and pick up later where they left off. You can define custom data in UEFN that can be saved and persisted for players across multiple play sessions. Best of all, Verse Persistence won’t count towards your island memory limits.

Verse Persistence is built into Verse as a native language feature. This is the first step towards creating a metaverse where players interact and play in worlds that persist.

Could you post this as a bug report on our forums so it can be tracked? https://forums.unrealengine.com/tags/c/general/issues-and-bug-reporting/172/fortnite

We’re aware that some device options of the HUD Controller Device were added Fortnite Creative and UEFN early. Since these options are unfinished and could cause issues, they will be removed until further notice. We’ll keep you posted.

We have identified a bug associated with Island Persistence that can cause users to fail to write persistent data.

Islands containing very high numbers of persistent creative devices can experience write failures to the underlying save data backend services. These errors can also be triggered by adding Verse Persistent data to such islands.

We have identified a fix for this issue and it will be included in the 29.10 release. In the meantime, we recommend that you playtest any island changes that involve adding new persistent creative devices or changes to Verse persistent data. If you encounter connectivity issues in playtests you should not publish those changes publicly.

If you experience data write errors or connectivity issues in your island after adding Verse Persistent data or increasing the number of persistent devices in your island, please report the bug here.

We will start experimenting with Square Thumbnails in Discover soon, so don’t forget to add a square thumbnail in addition to your existing tile in the Creator Portal.

We’re aware that player data (eliminations, scores, item grants, etc.) was reset for some islands after they were reverted by creators to a previous version following the release of v29.00.
We are offering a one-time player data restoration service for islands that were reverted.

You can find more info and apply here:

If you open a UEFN project that has Verse code that previously compiled successfully but currently has Verse code that will not compile in the current version of the compiler, you may run into a case where you will encounter errors unrelated to your code. This may also persist across opening different projects until you restart the editor.

This will be fixed in an upcoming UEFN release. However, to workaround the issue for now, please delete the snapshot data for your project and restart UEFN. This folder should be located at: %localappdata%\UnrealEditorFortnite\Saved\VerseSnapshot\

You can also fix this by making sure that your Verse code compiles without any errors, before attempting to open it in UEFN.
