MPPM - Disable CloneSceneChangedHandler

Unity Engine
1

Hello!
Trying out MPPM. I often use EditorSceneManager.playModeStartScene to first load an initialisation/ entry scene before loading into the desired scene. Something like this usually:

[InitializeOnLoad]
public static class BootLoader
{
    static BootLoader()
    {
        EditorApplication.playModeStateChanged += OnPlayModeChanged;
    }
   
    private static void OnPlayModeChanged(PlayModeStateChange obj)
    {
        if (obj == PlayModeStateChange.ExitingEditMode)
        {
            EditorSceneManager.playModeStartScene = AssetDatabase.LoadAssetAtPath<SceneAsset>("Assets/Boot.unity");
        }
    }
}

This seems to confuse MPPM since it tries to sync the boot scene, I get this error:

ArgumentException: Scene file not found: 'Boot'.

Is it possible to just disable the CloneSceneChangedHandler?

Hi @MylesLambert , I redirected your question to the MPPM team and I’ll write here again once I have an answer to it!

Hey @MylesLambert , unfortunately currently there isn’t any workaround to that.

The team is aware of the issue and they’re going to figure out how to fix it in future relases of MPPM
