Epic’s asset store Fab got two changes on 15 October. You can now buy several assets at once as a bundle. And Fortnite creators can license editable “UEFN source assets”: complete systems such as AI, vehicles and menus that open straight in Unreal Editor for Fortnite. Both are useful, and both come with rules that are easy to miss, whether you’re buying or selling.

Bundles

A bundle is a set of products put together by one publisher, sold in a single purchase. Each item lands in your Fab library as a separate product, and the bundle itself doesn’t appear there. Fab’s announcement says bundle items use the same Fab Standard Licence as individual purchases.

Fab’s seller documentation sets out the rules:

  • A bundle holds 2 to 50 listings, and every listing has to belong to the publisher.
  • Each listing can appear in up to three live bundles.
  • Bundles can’t contain other bundles, and a live bundle’s contents can’t change. To add something, the publisher makes a new bundle.
  • Creative Commons listings can’t go in a bundle.
  • Sellers can’t put savings claims such as “50% off” in a bundle’s title, thumbnail or description. Fab shows the price comparison itself.

The catches for buyers

Bundles don’t have to be cheaper. Fab doesn’t require the bundle price to be lower than the items bought separately. It shows you the difference automatically, and a negative difference shows in red. Look at that number before you assume you’re saving money.

You pay full price even if you own some items. Fab doesn’t take off the price of anything already in your library. You’ll see a notice, but the bundle price stays the same. If you already own half the bundle, buy the other items one by one instead.

Refunds are all or nothing. You can only refund a bundle as a whole, not one item from it. You also can’t have a bundle and one of its items in the same cart.

Sales change the maths. A sale on an individual item doesn’t change the bundle’s price, but it does change the comparison. During Fab’s sales, the separate items can end up cheaper than the bundle.

Pick the right licence tier. Fab’s Standard Licence has two tiers. Personal is for buyers with gross revenue of US$100,000 or less over the past 12 months. Professional is for anyone above that. Bundles are priced separately for each tier, so check you’re buying the one that matches your studio.

UEFN source assets

Until now, Fortnite creators could buy assets with a “UEFN Reference Only” version. That gives you an asset to use through its Verse path, but no project files. A UEFN source licence is different. You get the publisher’s project files to download and edit. It falls under the Standard Licence, and there’s no Reference Only version.

Epic’s Fortnite announcement describes them as complete systems: AI and NPC behaviours, vehicles, weapons, interfaces and environments. Many are built with Verse, Fortnite’s scripting language, and Scene Graph, its entity system. Launch examples include:

  • Verse UI Kit from Epic, which is free. It has buttons, sliders, tabs, dialogs, settings panels and example screens you can restyle.
  • Pathfinder from TrickTyger, an animated arrow trail that moves to the next target when the player arrives.
  • Environment packs from Dexsoft Games: an office, a bowling alley and a sci-fi control room.

You license them on Fab or from the Fab window inside UEFN. Epic says the asset lands in your Fab library and stays there, and you add it to a project through that Fab window. Epic also says each listing is checked against UEFN technical standards before it goes live. Fab’s seller upload guide adds that Fab doesn’t open your project or check it works, so testing is the seller’s job.

Can you use them outside Fortnite?

We couldn’t confirm it either way. Epic’s announcements, forum posts and Fab’s licence docs only talk about UEFN. The closest thing to an answer is the plain-language summary on Fab’s EULA page, which says you can use assets with any compatible tools, not only Unreal Engine. That summary isn’t the binding licence text, and it doesn’t mention UEFN content.

So if you’re hoping to buy a Fortnite AI system and drop it into a standalone Unreal game, don’t assume you can. Individual listings also carry their own restrictions. Read the licence details on each listing, and keep a copy with your project records.

For sellers

If you build Fortnite systems, this is a new market. Fab’s publisher announcement says sellers keep 88% of net revenue on each sale. Uploads opened on 21 September. You need to be a Fab publisher, and your source assets should be built with Verse and Scene Graph. Free source assets are allowed too.

Bundles are also worth a look if you sell asset packs. They let you sell a themed set at one price without making a new combined listing. Keep the three-bundle limit per listing in mind, and remember that you can’t change a bundle once it’s live.

Should you care?

You are Our verdict
Buying assets on Fab for any engine Bundles can save money, but check the price comparison and what you already own first.
Making Fortnite islands Start with Epic’s free Verse UI Kit. It’s a low-risk way to see how source assets fit into your project.
Hoping to reuse UEFN systems in your own Unreal game Don’t assume you can. Check each listing’s licence.
Selling on Fab Bundles are an easy win for existing packs. UEFN source assets are worth it if you already build in Verse.
Not using Fab or Unreal Nothing changes for you.
