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.
