UnrealClaude
Claude Code CLI integration for Unreal Engine 5.7 - Get AI coding assistance with built-in UE5.7 documentation context directly in the editor.
You see the problem is, inside Unreal Engine everything is serialized binary data, stored as a .uasset file. So when I fire up Claude Code to have him review my blueprints, he can't. I search all over the internet, scouring in shock and dismay that somehow this is not a well solved problem. How is it even possible there isn't a full solution for this already, that an LLM can understand what's inside a .uasset? Admirable folks had begun putting up the foundations, but the gap was still very real. I started with the UnrealClaude plugin https://github.com/Natfii/UnrealClaude as the base (shoutout to Natfii, he created a lot of the base capabilities I built on top of, could not have done it without him). It has capability to create blueprints, but limited capability to parse existing ones as an exposed operation. So I leverage existing code in the plugin, and extend it so it can read blueprints in Unreal. And after that — aha! One of the boxes in one of the nodes was 1 when it should have been 10, Claude caught it first try once he could see it. Roadblock removed, I am back on track!
