Understand and Create
Your Unreal Engine Node Graphs

Blueprints. Describe what you need and get a fully wired Blueprint from the AI you already use - pins, execution flow and variables all correct. Or open one you didn't write and ask how it works: the explanation is drawn on the nodes. Review it on canvas, then paste it into Unreal or deploy it in one click.

Download for Windows See how it works ↓

Use AI to understand Unreal rather than avoid understanding it.

01Not just generation

Learn how any graph works.

The same AI tools work on any graph you load: ones you generated, ones you pulled in from Unreal, ones you inherited from someone else. GraphDeck turns visual scripting you didn't write into something you actually understand.

Why does the door glide open instead of teleporting? Start at the trigger.
Only the player passes - everything else fails the Cast and stops here.
Update fires every frame while the Timeline runs - that's the animation clock.
Each tick adds delta × 2 - Door Alpha climbs 0 to 1 in half a second.
Alpha drives position, not speed - pause the clock and the door freezes mid-slide.
Every frame the mesh is placed at the eased position - motion is emergent.
Finished fires once, when the slide lands - the creak plays at the door.
Overlap → gate → clock → alpha → blend → move - six links, one glide.

Why does the lava crawl on its own with no timeline anywhere?
Panner offsets the UVs a little every frame - scrolling is free on the GPU.
The noise is the mask - dark crust where it's low, molten where it's high.
Emissive is light, not colour - the ×20 strength is what makes bloom bite.
Only pins wired into the Result exist in the compiled shader.
UVs scroll → noise masks → Lerp colours → Emissive glows. Four stages, no code.

Same tree, same look - so why is there no Tick anywhere in this widget?
Heal is an event, not a poll - this chain runs only on the click.
Set Percent writes the bar directly - no binding, no per-frame cost.
The preview is live - this exact tree is what deploys to Unreal.
Tree defines look - events define behaviour - nothing runs per frame.

The base pose comes out of a full state machine living in here.
Idle blends in by Alpha - two pose streams become one.
IK bends the arm after animation - order is the whole trick.
State machine → blend → IK → output. One pose, four stages.

Every frame starts here - the execute chain is the solve.
Basic IK bends the chain so the hand reaches its target.
Damp smooths the weight - the control lands softly, never snapping.
Event → solve the chain → write the control. That is the frame.

Explain

Ask for an explanation and the AI teaches it like a lesson at a whiteboard.

  • The camera glides through the graph while rings, arrows, and notes land on the exact nodes it's talking about, and you page through at your own pace.
  • Lessons follow the logic across EventGraph, functions, and Construction Script, and can be saved and replayed.
?

Ask

Ask questions about what's on your canvas:

"What happens when the player presses E?" "Could anything go wrong with this?" "How could I optimise this material?"
  • Answers arrive drawn on the graph itself, anchored to the actual nodes, not as a wall of chat text.
  • When a lesson calls for it, the AI can even sketch a suggested addition in chalk - nothing changes unless you accept it.

03How it works

Generate a Blueprint from a description.Generate a Material from a description.Generate a Widget from a description.Send it over from Unreal. One click.

1

Describe what you needSend it from Unreal

Type what you're trying to do, or pick from the built-in prompt patterns.One click on the Connector's Send button - or copy nodes in the Anim Blueprint or MetaSound editor and paste them straight in.

2

Get a working graphIt lands as Unreal drew it

Not a list of nodes. A fully wired graph with correct connections, pin types, and execution flow. Auto-laid-out and ready to read through before you commit.Tabs, state machines, pin trees, knobs, and wire colors arrive exactly as the editor shows them - validated against the real node library on arrival.

3

Send it to UnrealUnderstand it, edit it, keep it

Export copies native Unreal clipboard data. Paste straight into the Blueprint or Material editor. Want to skip the clipboard? The free Connector plugin deploys directly into your project.Ask the AI you already use to explain it on the canvas, tweak it, save it to your library - and copy supported graphs straight back into Unreal.

Not a mockup - every node, pin, and wire is from a real generated graph, validated in GraphDeck.

Extend

Select nodes and ask the AI to build from them. "Add sprint with stamina that drains and recharges." It reads what's already there, wires into your existing graph, and adds only what's needed.

Round-trip: native Unreal clipboard data works in both directions.

05Generate a Blueprint. One click. It's in Unreal Engine.

The Connector plugin. Download the beta.

GraphDeck works perfectly with just the clipboard. The Connector plugin takes it further: deploy Blueprints and Materials straight from GraphDeck with a single button. Free, in open beta.

Free plugin. Drop it in, enable it, GraphDeck finds it automatically.
Two-way. Deploy from GraphDeck or pull assets back in for reference, editing, or AI explain.
Localhost only. No cloud, no telemetry, no internet required.
Download the Connector ▾
Unreal Engine 5.8 Unreal Engine 5.7 Unreal Engine 5.6 Unreal Engine 5.5 Unreal Engine 5.4
Read more about the Connector →

Direct download for UE 5.4 - 5.8. The Fab listing comes later. It's beta software - stable in our testing, and nothing touches your project until you hit Deploy - but keep your project under source control and use it at your own discretion.

Let your AI assistant use GraphDeck Best way

MCP server, built in

Connect an assistant like Claude and it drives the whole workflow: it builds graphs live on your canvas, looks things up in your library, and checks its own work against GraphDeck's validation. With the Connector plugin it reaches into Unreal too - pull Blueprints and Materials in, deploy back, compile and verify. You approve anything that touches your library or your project, and Ctrl+Z undoes any build.

Copy-prompt workflow

No API key needed

GraphDeck builds a detailed prompt for you. Copy it, paste into whatever AI you already use (ChatGPT, Claude, Gemini), and paste the response back - GraphDeck turns it into a wired, validated graph.

Works with any AI · Requires a free account with the AI provider

GraphDeck Gems

No API key needed

Pre-built Gemini Gems: custom AIs that already know every node, pin type, and syntax rule for each mode. Copy a short prompt, paste it in, copy the response back. Same clipboard flow, better results.

Requires a free Google account · Powered by Gemini
Blueprints Gem →Materials Gem →

Direct API key

Optional

Plug in your own API key from Anthropic or OpenAI and generate directly inside GraphDeck. Faster if you're doing a lot of generation, and the cost per graph is fractions of a penny.

Your key · Your account · Stored locally · Pay per use
Studio-safe by design

You choose what leaves your machine.

Standalone by default

Works without a plugin, without project access, without the engine running.

Local only

Clipboard or plugin, nothing leaves your machine. AI calls use your own keys.

Counts, never content

Telemetry is anonymous feature-use counts from a fixed public list. Never your graphs, prompts, or project data.

The AI never sees your project

It only receives node names, pin data, and what you type. Never your files, assets, or source code.

No lock-in

Everything GraphDeck creates is a standard Unreal Engine asset. Uninstall anytime. Nothing breaks.
