Animation Node Reference

Descriptions of the various animation nodes available for use in Animation Blueprints.

An Animation Blueprint (AnimBP) is a special class of Blueprint that specifically controls an object's animations behaviors. AnimBPs are divided into two graphs, the EventGraph, for controlling the animation logic and interaction behaviors, and the AnimGraph, which controls the animation pose output for the object. Each graph within an AnimBP uses nodes to perform operations. These nodes can be classified into a few distinct types based on their function in an AnimBP.

Animation Node Structure

AnimBP nodes on the AnimGraph and EventGraph can have input and output pins in which information can be passed.

input and output pins

AnimBP nodes can also have property pins, such as data values or variables that can be modified with linked functions in the AnimBP AnimGraph and EventGraph.

property pins

AnimBP node properties can also be accessed in the node's Details panel after selecting the node in the AnimBP.

EventGraph Nodes

Event graph nodes are used to process incoming data that in turn is used to drive the pose data in the Anim Graph, such as triggering playback, activating or disabling animations functions, and updating animation data.

With the Animation Events documentation, you can reference the function and properties of EventGraph AnimBP nodes.

AnimGraph Nodes

Using data from the EventGraph, AnimGraph nodes determine the actual frame-by-frame pose to use for the animating object.

Animation Node Pose Watching

When working in an AnimBP, you can toggle Pose Watching on specific AnimBP nodes to see a color coded debug drawing of the pose that it is generating in the Viewport.

To toggle an AnimBP node to pose watch, right-click on a node that contains pose data and select Toggle Pose Watch from the context menu.

You can also have multiple nodes toggled to Pose Watch at once, allowing you to compare poses at different points in the AnimBP to find the exact point in which any errors in your current pose are introduced.


By clicking the icon in the upper left corner of the node You can hide the node's watched pose. To change a node's watched pose color, open the Pose Watch Manager by navigating in the Menu Bar to Window > Pose Watch Manager and select the color option next to the desired pose.

You can disable a Pose Watch from the color picker window or by reselecting Toggle Pose Watch on the Animation Node.
