Summary
I am experiencing an issue with the Day Sequence Device in UEFN where the configured time of day does not appear to apply correctly when testing my island in a session or using a private island code. I have two Day Sequence Devices: one configured for nighttime in the main gameplay area and another configured for sunset in the lobby. In both cases, the sun remains at approximately 12:00 PM instead of changing to the configured time. However, the fog and other lighting settings appear to work correctly. I have already adjusted the device priorities, but the issue persists.

Devices
Steps to Reproduce
- Open a UEFN project, then add a Day Sequence Device
- Configure the main gameplay area’s Day Sequence Device to use nighttime
- (Optional) Configure another Day Sequence Device to sunset, and set the priority correctly for the lobby.
- Launch a UEFN session and observe the sun’s position and time of day.
- (Optinal) Run a private island test code to see if it is still broken
- Compare the results with the lighting and time-of-day settings in UEFN.
Expected Result
The main gameplay area should display nighttime, with the sun and sky reflecting the configured time of day. The lobby should display sunset, with configured settings consistent in the UEFN session and private island playtest.
Observed Result
In both the UEFN session editor and the private island code session, the sun remains at approximately 12:00 PM. I expected the same when the game is released to the public.The main gameplay area remains in daytime instead of nighttime, and the lobby remains in daytime instead of sunset. The Fog and other lighting settings appear to apply correctly. Adjusting the device priorities has not resolved the issue.

Additional Notes
I don’t have a video of it, but kind of. I posted a gameplay teaser of the game, and you can see that it is daytime in the main area. Then the images that I have: the top one is in UE; the bottom image is what it looks like in-game around the same spot. You can see it is sunset in UEFN, but in the session editor it is not.
