Utilizing Initial Keyframe

info

This section uses the MainLevel map of the RealityExamples template, compatible with Reality Engine version 4.27. It is the default project that comes with a fresh installation. After launching the Reality Editor, you can create the same project through the Virtual Studio template. For more details, visit Reality Examples Project

To utilize the Initial Keyframe:

Example Node Tree and APM

Launch the MainLevel map of the RealityExamples template
Create the node tree as shown above and activate the APM

UserTransform Property of UserTrack Node

Select the UserTrack node, expand its Input property group, and change the UserTransform property values as shown above

Keygrame Type

Create a new Action, add the UserTrack node to the Action Timeline
Right-click on the Property Circle of UserTransform, select the Add Keyframe
Scrub Playhead to second 2, add another keyframe
Select the first keyframe, and change the keyframe type to Initial, as demonstrated in the above image

Interpolation

Select the second keyframe, change its interpolation to EaseInOut

Playing animation in this state will not render anything.

To see the effect:

Select the UserTransform node, activate the GamePad button
Hover your mouse over the GamePad, change the Camera view
Click on the Play button

Now, pressing the Action Timeline Play button takes your camera's latest position and animates it with EaseInOut interpolation within 2 seconds of your Initial Keyframe's location.
