UEFN level design: blockouts, routes and devices with AI

UEFN level design: from blockout to playable level

The agent starts from what the player does: the island’s objective, player count, available movement, intended travel time. It then reads the active map, its coordinate system, its units and the assets already in your project.

Then it lays down the smallest useful blockout:

• a main route and an alternate path;
• encounter spaces and cover;
• clear boundaries and safe spawn points;
• visible landmarks to find your way.

It reuses your assets and conventions instead of imposing a new grid or folder structure. Decoration comes later: a routing problem isn’t solved with set dressing.

Place actors and devices, then read back

The Level Designer works through the placement tools the editor exposes, and it stays careful:

1. it inspects one placement before repeating it;
2. it only changes the intended actors and keeps an identifiable group so changes can be undone;
3. it checks it is placing the right device variant, since several can share a name;
4. it reads transforms and settings back after each change, because a write that answers “ok” proves nothing;
5. it moves unused parts out of the way instead of deleting them, and records the offset to restore them.

When a device needs to react to code, the Verse Coder writes the script and wires its references. Custom buildings or a modular kit can come from Blender or Meshy: see 3D models.

What the agent checks in your island

Sightlines

No unintended structural advantage for one team

Spawns

Spawn exposure, getting back to the action after elimination

Flow

Dead ends, clearance to pass, ambiguous jumps

Objectives

Visible and reachable with the movement you enabled

Terrain and collision

Using the tools actually available

If a capture tool is available, it looks at an editor view. It also proposes a test route that works without verbal guidance: find the objective, reach the action, understand a branch, return after an elimination.

Example requests

• “Block out a 3-lane arena with cover.”
• “Place a counter and two upgrade buttons in my tycoon’s shop area.”
• “Check that red team’s spawns can’t be seen from the tower.”
• “Add a zone that lowers gravity above the lake.”

For a request that mixes level, code and enemies, the orchestrator splits the work between the Level Designer, the Verse Coder and the NPC Author: see the AI agent team.

What stays in your hands

Some terrain or placement operations can’t be automated with the current editor: the agent names them instead of working around them. You need a Windows 10 or 11 PC (64-bit) with UEFN and its MCP turned on, plus your AI subscription.

FAQ

Can AI block out a Fortnite map?

Yes. The Level Designer places the base volumes and actors with the editor’s tools, starting from routes, cover and spawns, then reads every placement back.

Can it configure UEFN devices?

Yes, when the editor exposes their settings: it places the device, checks its variant, writes its properties and reads them back. Wiring to Verse code goes through the Verse Coder.

Will it delete parts of my island?

It only changes the intended actors. To make room, it prefers moving unused pieces out of the way and recording the offset rather than deleting them.
