Are scenes in the assets folder the same as scenes in the build index?

I’m asking this question because I have a special case for my application (too much to explain)

  • What I’m doing: I’m downloading a scene as an asset bundle at runtime and putting it into the Assets/Scenes folder so I can load it by index.

  • How this relates to my question: I need to know if the scenes in the assets folder will line up the same way as in the editor (Scene 1 = index[0], etc…)

The Scenes you put in your Project Window or Assets Folder can be in any order. That does not mean that a Scene named Scene 1 will come up as Index 0 in your Build Settings. And you can change the order of your scenes in your Build Settings by dragging it to the appropriate position.
I hope you will get your answer after visiting the following Unity Forum
