Fortnite UEFN Mega-Bot Arena

I want a publish-ready 1v1 training island built in Unreal Editor for Fortnite. Picture a vast, polished floor under a moody neon sky where up to 10,000 AI bots can flood the play space without a hitch. The entire experience has to feel absolutely smooth—no perceptible input lag, stable high FPS, and zero hitches even after ten-hour stress tests.

Scope
• Design and block-out the arena so movement, line-of-sight, and spawn logic encourage fast mechanical practice.
• Script bot spawners and behavior trees so the AI pours in continuously, keeping players engaged yet not crippling performance.
• Handle all optimization passes—Lumen/Nanite settings, instancing, culling, clever NavMesh segmentation—to make the map run cleanly on PC, console, and, if feasible, mobile.
• Light the scene in a rich, dark-neon palette; I’m after that modern esports vibe, not a cartoon glow-fest.
• Package, test for a full ten-hour loop, and supply the island code plus a quick setup/maintenance doc.

Acceptance Criteria
1. 10,000 simultaneous bots spawn and respawn without crashing or dropping FPS below 60 on desktop and current-gen consoles.
2. Player input delay remains under 30 ms in local test.
3. No critical memory leaks or nav errors after ten continuous hours.
4. Final island is approved by Epic and live-publishable; you provide the island share code and source files.

I’ll stay available for quick answers on art direction or gameplay tweaks, but the technical execution is yours. If you’ve already pushed the limits of UEFN performance before, this should feel like home. Let’s build the arena every grinder wants to queue into.
