VR Level Loading Screens not packaged

Hi all,
I have been trying to get Level-Loading screens in my VR project following these instructions (a.o.) XR Loading Screens | Unreal Engine 4.27 Documentation | Epic Developer Community
These work perfectly in Editor but as soon I create a build, they are not being displayed when switching levels.
I have tried:

  • adding the texture being used in one of the levels to make sure the assets is being packaged
  • calling the SetLoadingScreen (but also AddLoadingScreenSplash) in the Level BP, Pawn and an actor present in the persistent level.

All combinations work fine in PIE but are a no-show when packaged.

What am I missing here?

[Edit] Working with 4.27 for this project
Thanks for your time,
Pascal

is it a movie? like a video that plays while loading because in that case theres a specific area in the settings, i think under ‘package’ where you need to specify any movies to be packaged

Nope, just a regular png/Texture asset.
