Price

Paid plugin on Fab, or an Indie monthly plan with AI tokens included

Works with

Unreal 5.7–5.8 (Windows)

A Fab plugin (formerly Ultimate Blueprint Generator) that builds Blueprints, C++, UI, VFX and levels, can play-test a level and profile frame rate, and generates models, textures and audio in the editor. Run it on the seller's models, your own API keys, local models through Ollama or LM Studio, or drive it from Claude Code. It asks before editing. Windows only, and the listing states no terms for what it generates.
