🔥 Unreal Editor for Fortnite (UEFN) just dropped its most powerful update so far — and it’s a total game-changer for creators.

From smarter tools to real-time AI and official IP integrations, this update isn’t just technical — it’s creative freedom, leveled up.

At Karta, we’ve been building at the cutting edge of UEFN since day one — and here’s what has us most excited:


🪵 Nanite Foliage

Build dense, high-fidelity forests with real geometry — no more flat LOD cards. Every leaf, branch, and pine needle now renders beautifully in-game.

🤖 AI NPCs & Game Logic

Talk to NPCs powered by large language models — and let them drive your game logic. Personality, storytelling, emergent gameplay — now in your hands.

🧱 LEGO Brick Editor (June 17)

Brick-by-brick LEGO building inside Fortnite. 50+ pieces, 42 colors, and full official tooling.

📊 Fortnite Data API (June 9)

Access real performance data for every island. Track plays, trends, and metrics — and grow smarter.

🛠 Epic Developer Assistant

Your new AI sidekick. Write code, fix errors, explain logic — inside your workflow.

🎭 Metahuman Animator (Live Now)

Animate faces using just your webcam. Real-time, realistic facial performance from anywhere.

🎮 Scene Graph (June 7)

Prefab-friendly, modular hierarchy with full Verse access — making complex builds way more efficient.

✨ More Official IP

Squid Game (June 27), Avatar (2025), Star Wars (coming soon) — each with usable tools, assets, and gameplay systems for creators.


UEFN is evolving rapidly — and so are the creative possibilities for branded experiences, custom game modes, and storytelling.

Karta is building right in the middle of it.
