Open up any Control Rig.
Rig graphs, explained.
Solve graphs get dense fast - IK chains, space switches, constraints stacked deep. Open yours in GraphDeck and ask the AI you already use how it works: lessons drawn on the rig itself, with animated sketches of what each chain is really doing, labelled with your own bone and control names.
Solve graphs with full pin trees
Solve events in Unreal's red, rig units in steel blue, pure math in green - the exact tints the Control Rig editor uses, execute chain and all.
From a rig in Unreal to a solve you can follow
One click in the Unreal editor (free Connector plugin) sends a Control Rig to GraphDeck - the Forwards, Backwards, and Construction solve graphs and your function graphs each arrive on their own tab.
Rig units with full pin trees you can expand item by item, solve events in Unreal's red, mutable units in steel blue, pure math in green - the same role tints the Control Rig editor uses, with the execute chain drawn through them.
Lessons can draw the classic blackboard machines, animated: a two-bone leg reaching its goal, a chain crawling to a target, a knee following its pole vector, a bone snapping between parent spaces, a jiggle spring overshooting and settling - each labelled with your rig's own bone and control names.
Save the rig graph as a .gdeck file, lessons included. Open it in any project later and replay the explanation - each replay revalidates against the current graph.
Use AI to understand Unreal rather than avoid understanding it
Control Rig graphs are dense by nature: hundreds of units, execute chains that fork per solve, pin trees four levels deep. GraphDeck's Explain & Ask lessons - powered by the AI you connect, not an AI of GraphDeck's own - teach on the canvas: stepped walkthroughs across solve and function tabs, notes anchored to the actual units, and animated mechanism sketches that show what an IK chain or a space switch is really doing, using your bone names.
Every mark is validated against the live graph before it draws, and validation cross-checks bone and control names against the rig's own hierarchy - so the lesson can never drift from the rig.
Built for the rigs you already have
The full Control Rig node library
Hierarchy, transforms, IK, constraints, simulation, splines - the rig units resolve against a library built from the real editor, with full pin trees.
Solve graphs as tabs
Forwards, Backwards, and Construction solves plus function graphs, each on its own tab - and a single lesson can walk across them.
Validation that knows rigs
Bone and control names are cross-checked against the rig hierarchy with nearest-name suggestions, and a rig that compiles in Unreal stays green in GraphDeck.
Mechanism sketches
Piston cranks, two-bone legs, pole-vector knees, parent-space switches, jiggle springs - animated chalk machines that explain the concept on your actual rig.
Common questions
Can I open a Control Rig outside Unreal?
Yes. With the free Connector plugin, one click in the Unreal editor sends a Control Rig to GraphDeck - the Forwards, Backwards, and Construction solve graphs and function graphs arrive as their own tabs.
Can AI explain my Control Rig?
Yes. GraphDeck turns the AI you already use into a teacher on the canvas: stepped lessons across solve tabs, notes anchored to your actual units, and animated mechanism sketches - a two-bone leg, a pole-vector knee, a space switch - labelled with your rig's own bone and control names. GraphDeck has no AI of its own - it works with the AI you connect.
Can AI generate Control Rigs?
AI generation for Control Rig is coming in a later update. Today's tools cover receiving, reading, editing, validating, and understanding the rigs you already have.
Does it change my rig?
No. Receiving is read-only: the plugin sends a copy of the graph to GraphDeck, and your Unreal asset is never touched. Edits happen on GraphDeck's canvas and stay in your .gdeck files.
Is this in the free edition?
Yes. Receiving, editing, validation, and Explain & Ask lessons all ship in Free. Free keeps 5 saved graphs in each tool; buying GraphDeck removes the caps.
