Hello everyone, I'm new to Unity and trying to implement a persistent scene that adds/removes scenes additively. My first issue is I'm not clear how to handle this scene not having a camera since it gives an error. Can I ignore that and just use the ones that are in my scenes that I load? Or is more common to have them all placed in the initial scene and toggle them/on or off?
The second thing I'm struggling with is I want to have a progress bar load between scenes. My first attempt at this was to have a "Loading" scene which I bring in. However I then found out that my SceneManager script can't have references from another scene. So, I'm not exactly sure how to control the loading bar progress (for example).
I've watched literally dozens of videos/tutorials on loading bars and scene managers and I'm having a lot of trouble because a lot of the approaches are more complicated than I need and everyone is doing it different. I would appreciate any thoughts/comments/help.
