“I told Claude to build me a medieval village and it spawned 40 actors, set up materials, and arranged everything in under a minute. With full undo. This is the future of level design.”

“We populated a 16 km² open world in an afternoon. The biome zones and exclusion system meant we barely had to touch anything after the initial scatter.”
Environment Artist
AAA Studio
“We cut our cutscene production time by 70%. The filmback presets and dolly zoom alone are worth the price — our trailer went from 'indie' to 'studio quality' overnight.”
Technical Director
Indie Studio
“We dropped this into our RPG prototype and had health bars, inventory, dialogue, and quests running in a single afternoon. It would have taken us 2-3 months to build all of this from scratch.”
