Benutzerdefinierte Items und Inventar erreichen die Beta für veröffentlichbare Inseln

Epic’s 40.20 Fortnite ecosystem update, published on April 16, 2026, moves Custom Items and Inventory into Beta. Epic says creators can now publish islands with the feature enabled, giving UEFN teams more control over player inventory systems and custom gameplay loops. Epic’s release notes describe use cases that include custom items, inventory-driven gameplay, in-game economies, and crafting mechanics.

What changed in practice

• Creators can publish with Custom Items and Inventory switched on.
• The system is no longer limited to private experimentation only.
• Epic says the feature can support fully custom gameplay and economy designs.

The update also says Epic removed `@experimental` from all Custom Items and Inventory classes, signaling that the workflow is ready for wider creator use. For studios building progression-heavy islands, that is a meaningful step because inventory rules often shape combat pacing, reward loops, and monetization design. Source

Why this is important now

This is one of the clearest recent signs that Epic wants island creators to build more complete game systems inside Fortnite, not just level layouts and minigames. With publishing enabled, the feature has real production impact rather than being a sandbox-only test. Epic documentation
