Blueprints Mode

Blueprints mode is GraphDeck's primary mode: a complete pipeline for generating, viewing, editing, and deploying Unreal Engine Blueprint graphs.

Node Library

Browse and search over 5,000 Blueprint nodes across every major Unreal Engine system. Filter by category, search by name, and drag nodes onto the canvas. The library covers gameplay, AI, animation, physics, UI, networking, and more.

Multi-Graph Tabs

Real Blueprints have multiple graphs: EventGraph, custom functions, Construction Script. GraphDeck supports this with tabbed graphs. Each tab is its own canvas with separate nodes and connections. Variables and components are shared across all tabs.

AI generation can create multiple graphs in a single prompt: an EventGraph, a Construction Script, and custom functions all appear as separate tabs, correctly referencing each other.

Component Validation

A built-in library of 292 Unreal Engine component classes. When your graph references a component, GraphDeck checks it against the library, detecting abstract classes that can't be instantiated and suggesting corrections for unknown class names with "did you mean?" recommendations.

Type Validation

Automatic type-compatibility checking between connected pins. When types don't match directly, GraphDeck suggests auto-converter nodes: int to float, vector to individual floats (Break Vector), rotator to vector, and more.

Cross-Tab AI Explain

Ask the AI to explain an entire Blueprint across all its graphs. The explanation walks through each section with colour-coded groups, automatically switching between tabs as it moves through EventGraph, functions, and Construction Script. Useful for understanding marketplace assets or a colleague's work.

Clipboard Round-Trip

Copy nodes from Unreal Engine's Blueprint editor and paste them into GraphDeck. They render on canvas with the same layout and wiring. Edit or extend them, then export back. The clipboard format is Unreal Engine's native format, so it works both ways.

Blueprint Deploy

With the Connector plugin, one click creates a complete Blueprint in Unreal Engine: variables with correct types, components with full hierarchy, node graphs pasted into EventGraph, Construction Script, and custom functions. Compiled and saved.
