This section will guide you on operating the Actions by navigating and then animating a Property/Function.
Before you begin:
Activate the Nodegraph/Actions module
Click on the Actions button on the bottom-right corner
To create a new action:
Click on the plus icon or New Action button to reach the Actions UI.
Navigating
RealityHub offers various methods to help you quickly navigate inside the Actions:
Adding a Property to Timeline: To add a Property to the Timeline:
Select a node
Go to the Properties panel, and find a property you want to animate/trigger.
Left-click over the Node Property Menu circle and select the Timeline

Animating a Property
RealityHub’s approach to animating is unique and easy to understand. This section will be animating a UserTrack node’s UserTransform property.
Add the following nodes to your Nodegraph View:
Camera node from the UE Camera Node Class
UserTrack node from the Tracking Node Class
Make the following connections:
EngineControl node’s Display input pin to Camera node’s Output pin
Camera node’s Track input pin to UserTrack node’s Track pin
Example Node tree
Your RGRaph should look like the image above.
Now:
Click on the Actions button and open the Action Panel; click on the New Action button.
Go to the Camera node’s Output pin, right-click and assign the Monitor - 1 to Channel A
Select the UserTrack node from the Nodegraph, go to the Properties panel and find the UserTransform property under the Input property group
Left-click on the UserTransform property’s menu circle, select the Timeline
Go to the first frame by moving the Timeline Slider handle
Go to the UserTransform property inside the Action panel, left-click and select Add Keyframe
Go to the 4th second, change the Y (Position) value to 500 and then change the Y (Yaw) value to -50
Add another keyframe to the UserTransform.
While your last keyframe is selected, go to the Keyframe Interpolation, select the EaseOut and click Play.
