See inside any Anim Blueprint.
State machines, explained.
See exactly what an Animation Blueprint is doing. Open yours in GraphDeck, ask the AI you already use how it works, and the answer lands on the graph itself - a token walking your state machine, notes pinned to the nodes that decide each blend. Understand it, then edit it with confidence.
Drawn the way Unreal draws it
Pose wires carry travelling beads, state machines and transition rules ride their own tabs, and every pin uses Unreal's exact colors.
From a Blueprint in Unreal to a graph you can read
One click in the Unreal editor (free Connector plugin) sends an Animation Blueprint to GraphDeck - state machines, function graphs, and the event graph all arrive as their own tabs. Or copy nodes in Unreal's AnimBP editor and paste them straight into GraphDeck: pose nodes, state machines, and event-graph nodes land on the right tab automatically.
Animation state machines with travelling pose-wire beads, transition circles that ride their wires, blend and IK and cached-pose nodes in the editor's own colors, and pin and wire colors that match Unreal exactly - all 21 variable types.
Right-click and ask. A lesson can put a token inside the state machine that walks state to state and pops each transition's real rule, or send chalk pulses riding the pose chain in execution order - drawn on your actual nodes by the AI you already use.
Ctrl+C on a received Anim Blueprint tab produces text that pastes cleanly back into the Unreal editor - including your edits.
Use AI to understand Unreal rather than avoid understanding it
Animation Blueprints are where visual scripting gets genuinely hard to read: nested state machines, transition rules hidden behind double-clicks, cached poses used three tabs away. GraphDeck's Explain & Ask lessons - powered by the AI you connect, not an AI of GraphDeck's own - answer on the canvas: handwritten notes anchored to the actual nodes, a walker that steps through your state machine popping each transition's real rule, pulses riding your real pose wires in evaluation order.
Every mark is validated against the live graph before it draws. If the AI names a node that does not exist, the lesson is refused - your graph is always the ground truth.
Built for the Anim Blueprints you already have
The full AnimBP node library
State machines, blends, blend spaces, IK, cached poses, montage slots - with validation that knows Anim Blueprints, like cached-pose checks that match caches by name across tabs.
Received graphs stay green
A graph that compiles in Unreal stays green in GraphDeck - across reopens, revalidations, and AI reads - instead of drowning in false "unknown node" noise.
Variables under your categories
The Variables panel groups under the same collapsible Unreal categories you set up in the editor, with real type chips and the tooltips you wrote in Unreal.
Multi-tab, like the real editor
AnimGraph, each state machine, and the event graph are separate tabs - and a single lesson can walk you across them, framing each idea where it lives.
Common questions
Can I open an Animation Blueprint outside Unreal?
Yes. With the free Connector plugin, one click in the Unreal editor sends an Anim Blueprint to GraphDeck - state machines, function graphs, and the event graph arrive as their own tabs. You can also copy nodes in Unreal's AnimBP editor and paste them straight into GraphDeck.
Can AI explain my Anim Blueprint?
Yes. GraphDeck turns the AI you already use into a teacher on the canvas: stepped lessons with notes anchored to your actual nodes, a token that walks your state machine and pops each transition's real rule, and pulses that ride the pose chain in evaluation order. GraphDeck has no AI of its own - it works with the AI you connect, with or without an API key.
Can AI generate Animation Blueprints?
AI generation for Anim Blueprints is coming in a later update. Today's tools cover the other half of the job: receiving, reading, editing, validating, and understanding the Anim Blueprints you already have.
Can I edit it and send it back?
Yes. Edit on the canvas, then Ctrl+C on a received Anim Blueprint tab produces native paste data that lands cleanly back in the Unreal editor - including your changes.
Is this in the free edition?
Yes. Receiving, pasting, editing, validation, and Explain & Ask lessons all ship in Free. Free keeps 5 saved graphs in each tool; buying GraphDeck removes the caps.
