Cinematic Sequence Object Movement Not Persisting or Visible Under Specific Conditions (Tabbing Out and Teleportation Scenarios)

General Issues and Bug Reporting
, , , , ,
1

Summary

  • Issue 1: When playing a sequence set to “Instigator Only” and “Force Keep State” to move an object, if the player tabs out of Fortnite for the duration of the sequence with the “tab out freezes screen” setting enabled and then returns, the object movement from the sequence is not visible.
  • Issue 2: When the player’s camera is teleported far away (via cinematic sequence device or by teleporting the player’s character) from an object moved by the cinematic sequence device and then teleported back, the movement from the cinematic sequence gets undone.

These issues appear related to how cinematic sequences handle object movement persistence during loss of visibility or focus.

Steps to Reproduce

For Issue 1:

  1. Create or load a UEFN project with a cinematic sequence device set to “Instigator Only” and “Force Keep State” that moves an object.
  2. Ensure the Fortnite setting for freezing the screen on tab out is enabled.
  3. Launch a session and set the sequence to start playing on PlayerAddedEvent.
  4. Tab out of Fortnite before the sequence starts.
  5. Tab back into Fortnite once the sequence is over.

For Issue 2:

  1. Create or load a UEFN project with a cinematic sequence device set to “Instigator Only” and “Force Keep State” that moves an object.
  2. Include mechanisms to teleport the player’s camera or character far away from the object and not facing the object (e.g., using another cinematic sequence or teleporter device) and then back.
  3. Launch a session and trigger the initial sequence to start the object movement.
  4. When the object moving sequence is finished, teleport the camera/character far away from the object.
  5. Teleport the camera/character back to view the object.

Expected Result

  • For both issues: The object movement from the cinematic sequence should persist, remain visible, and not revert upon returning to the game window or teleporting the player’s camera back to the object’s location.

Observed Result

  • Issue 1: The object movement is not visible; the object appears static or in its initial position, as if the sequence did not progress or update visually.
  • Issue 2: The object movement is undone; the object reverts to its initial position or state upon teleporting back.

Platform(s)
