EditorBuildSettings.asset used to be text, so if you wanted to mass select/unselect all scenes it was trivial to do, even in notepad.
Between Unity 4.2 and 4.3 this file changed to a nontext format, now I have to manually click on 80+ scenes in my project, one at a time.
Does anyone have any tricks to mass select/unselect all scenes?
Is there a way to revert these asset files as text?
If you enable version control in unity and force text, then all teh .asset files in ProjectSettings will be YAML… plain text.
Edit → Project Settings → Editor
Enable Meta Files for Version Control and for Serialization, force text.
wow, thanks for that nugget of info as I was finally able to open the EditorBuildSettings.asset.
however, it doesn’t solve my problem as I see all my levels are listed and I still get that error
