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.
