Set first scene

Hi this must be really simple but I can't find it. I have created my game and now I'm adding a main menu start screen but when I build it always starts on the game screen.

How do I set which scene the first which is loaded on start up?

In the Build Settings, from the File menu, you can reorder your scenes. Make sure startup is at the top of the list.

The Order in Build Settings doesn’t affect the Play Button at all.
It is only for when you actually Build/Export your Game.

It makes no sense at all that it’s still like this…

If you have a NetworkManager, you must move that to the scene you want to be default. The default scene will be set to the scene with the NetworkManager regardless of the build settings.

just reorder it using the mouse drag and drop them in the build settings window
