Cipher: My AI That's Actually Building Unreal Blueprints For Me

I’m tired of staring at the same Blueprint nodes for the third hour straight. So I built Cipher — an AI agent that plans gameplay systems in Unreal Engine and spits out commands to make them real. Cipher isn’t some fancy wrapper. It’s an agent that thinks through what needs to happen, then fires structured JSON commands over a Python bridge straight into Unreal. It duplicates Blueprints, adds cameras, spring arms, components, you name it. And it’s already doing more than I expected. Why the hell am I doing this? Unreal is powerful but the workflow can be soul-crushing. Want a new camera rig? Duplicate, tweak variables, hook up events, pray nothing breaks. Same crap every time you prototype. I got fed up repeating myself and decided to teach an AI to handle the boring bits so I could focus on the fun ones. How Cipher actually works I give it a high-level goal. Cipher’s planner figures out the steps, then outputs clean command JSON. A Python listener running inside Unreal picks it up and
