Objects missing, no VFX upon pressing play in level. Absent in rendering as well.

Hi!

I’m trying to render out a bunch of videos for a project, however I just noticed that when I press play or render them out, the level lacks a bunch of actors, VFX (Niagara Actors), etc. They show properly within the preview, and everything works great, but they’re completely absent within the render and play. I can’t find them within the outliner in play either. None of the objects has physics or anything, the level has no streaming, I have no clue what’s happening with it and have tried looking everywhere for any fixes.

It would be awesome to somehow fix them and make them appear and work properly, however if not, is there some way at all possible where I could just create a level sequence and record through preview and not render it out or something? I would appreciate any help at all. Thank you!!

My Unreal Editor version is 5.5.1

It sounds like they are on a level that is not being loaded. If these things that are missing are indeed on a sublevel you need to specifically load them in sequencer or you need to set the streaming method to Always Loaded.
