Animating a Property
RealityHub’s approach to animating is unique and is 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:
ENGINE CONTROL node’s DISPLAY input pin to CAMERA node’s OUTPUT pin
CAMERA 0 node’s TRACK input pin to USERTRACK 1 node’s TRACK pin
Your RGRaph should look like the image above.
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 1 node from the Nodegraph, go to the Properties panel, find the USERTRANSFORM property under the Input
Left-click on USERTRANSFORM property’s menu circle, select the Timeline
Go to the first frame by moving the Timeline Slider handle
Go to 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.
