If your camera is only going to be looking one way the entire time this might work. Instead of having world partition streaming being enabled on your character make another actor that has world partition enabled.
Then have it teleporting to the main character on a timer. Get the world location of the main character, add say 8000 (depends on your needs) or something in the appropriate direction and put that new number on the new actor. This is to make sure it stays with the main character.
Make sure though that the new actor you have made isn’t spatially loaded. Or else this won’t work.
Hopefully this helps!
