How do I save an object after changing material in play mode?

Tried again a couple of times, couldn’t work it out. The following screenshots are all I have as ill try to start over starting with these nodes. So I have no variables and nothing related to the saving stuff. What do I do? All I have is my save object setup, and my materials changed in-game. So hopefully you can see what I got, and maybe this time it will be easier to work it out.

So if you could please tell me what to do from here, that would be awesome! So after I finish this, I could study it myself :slight_smile:
