Well. Its been a long time. Lots of trials and turbulations. I got into data layers (don’t load affectively, lags) I got into level streaming (not supported well, yucky). level instancing (nice but didn’t have what I want). I looked into components. Badgered ChatGPT but no dice.
But then when I had given up all hope. No idea what I was going to do.
Then I just randomly stumbled upon a “random” (it seemed to me at least) configuration THAT WORKS.
So once you place the actor (doesn’t have movement component or nothing) you NEED to set that actors location. either attach it to a tick or some other timer. Or if it is stationary at begin event.
Then you might notice if your moving your character/actor it will randomly despawn. But it ain’t. World partition is deleting it. I don’t get it. What you need to do though is just hit the streaming source and your should be good to go. Make sure your streaming source is not spatially loaded. All the other actors need this though.
Anyway hopefully that helps someone. Took me over a month to figure this out.
