Every UEFN mapper knows this loop: ask an AI for Verse → paste it → 14 errors → half the devices don't even exist → give up and write it yourself. I spent months killing that loop. Verse Builder. You describe your mode in one sentence. It writes the Verse, compiles it against real UEFN, repairs its own errors, and only hands you the file once it's green. "deathmatch but with killstreaks…" → 0 errors. 21/21 mechanics. 5 devices. Drop it in your project. No hallucinated devices. No invented APIs. And when a mechanic needs setup on the editor side, it tells you instead of pretending it shipped. Coming very soon. 👀 #UEFN #FortniteCreative
