How can I have my character move between levels?

I currently have two different levels that I have designed. My goal was to set a trigger in each level so that I could move back and forth between them. I tried using the “Open Level” function and it would open the new level but I could not move or see any of my objects. Is there another way to go about using this feature or is there an entirely different way that works better? Any help would be great. Thanks

Try using Level Streaming.

The Open Level basically restarts the game and you lose everything you had.

Trying to establish the same thing, i have been able to go to and from levels but on the return i want my character position to update to outside the door it entered, so far it resets to the original player start. Trying to establish a save system that updates player position before entering the door, but to no avail yet.
