Keep dynamically created GameObject between scenes

[UnityUser1900]

I’m using DontDestroyOnLoad() to keep a GameObject added in the editor persistent between scenes but I’m at a loss as to how to keep a dynamically-created GameObject between scenes.

Here’s what I’m doing:

Scene A: A GameObject (x) added to the scene via the editor with a script that has a GameObject (y) as a variable. The script calls DontDestroyOnLoad() on the it’s parent GameObject (x) and loads mesh data from a file into the variable (y). The script then loads Scene B.

Scene B: x is preserved but the data of y isn’t.

I’ve tried calling DontDestroyOnLoad on y but it doesn’t seem to work. I know the model loading in Scene A works because I can see the data in the debugger (and I’ve tested rendering the result in Scene B without passing it from Scene A) but when I try and use y in Scene B I get this error:

MissingReferenceException: The object of type ‘GameObject’ has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object.

Nevermind, I fixed it. I was putting the call to Object.DontDestroyOnLoad() in the object’s (not GameObject) constructor. I moved the call to a MonoBehaviour event and it worked fine.
