Describe the behavior
Tell the AI what you want — a door that opens on overlap, a damage system, a vehicle controller. Plain English is enough.
AI Blueprint Generator for Unreal Engine
Generate Unreal Blueprints from a sentence
Describe what you want. Blueprint Stack creates the Blueprint, drops in the nodes, wires the pins, and saves the asset — directly in Unreal Engine 5.4+.
Built on top of Claude Code or OpenAI Codex through MCP. The AI does not just suggest code; it actually authors the Blueprint graph, connects execution and data pins, and leaves you with a working asset.

Workflow
How AI Blueprint generation works
Three steps from prompt to functioning Blueprint asset.
AI authors the graph
The AI calls Blueprint Stack tools to create the asset, add nodes, set defaults, and wire execution and data pins.
Iterate live
Inspect the graph, ask for tweaks, attach example screenshots, or attach existing nodes as context for refinement.
Prompts to working Blueprint
Real prompts you can use today, and what comes out the other side.
Prompt / 01
"Make a pickup that gives 25 health when the player overlaps it."
Result
A Pickup Blueprint with a sphere collider, OnComponentBeginOverlap event, health-add call, and Destroy Actor on use.
Prompt / 02
"Build a door Blueprint that opens with a timeline when interacted with."
Result
A Door Blueprint with a timeline driving rotation, an Interact interface, sound cues on open/close, and a closed-state bool.
Prompt / 03
"Add a damage system: a component that any actor can attach."
Result
A Health component Blueprint with current/max float, ApplyDamage and Heal functions, OnDeath event, and a clean public interface.
Prompt / 04
"Generate an inventory Blueprint backed by a struct array."
Result
An Inventory component, an Item struct, AddItem/RemoveItem/HasItem functions, and a UI-ready GetItems output.
FAQ
Frequently asked questions
Does this actually author Blueprint graphs, or just generate text?+
It authors graphs. Blueprint Stack exposes editor tools for creating Blueprints, adding nodes, connecting pins, and saving assets. The AI calls those tools live.
Which AI models can I use?+
Anything that speaks MCP. Claude Code and OpenAI Codex CLI are the most common choices. You bring your own model — the plugin does not bill LLM tokens.
Can I edit Blueprints the AI created?+
Yes. Generated Blueprints are normal UE assets. You can edit them by hand, version-control them, and ship them. The AI can also iterate on them on request.
Will it generate Blueprints I do not understand?+
You can ask for a walkthrough. The AI explains the graph it created, justifies node choices, and offers simpler alternatives if you ask.
Does it handle materials and Niagara VFX too?+
Yes. The same workflow extends to materials, Niagara systems, data tables, structs, and level building. 48 tools across 11 categories.
