Blueprint Stack Documentation

Blueprint Stack is an Unreal Engine 5.4+ editor plugin that bridges AI coding agents to the Unreal Editor. Connect to Claude Code or Codex, run open models locally with Ollama or LM Studio, or bring your own custom agent — then use 48 editor tools across 11 categories to create Blueprints, manipulate assets, generate materials, and more, all through natural language.
