GameObject.Find() in additively loaded scenes?

I load a scene at runtime additively with LoadLevelAdditiveAsync.
Looks like if - from the level of first scene object - I were unable to access additively loaded scene objects

  • with use of:

    GameObject.FindGameObjectsWithTag();
    GameObject.Find();
    FindObjectOfType(typeof(Type));

and the likes.
Has anyone also experienced this?

Are you sure you wait until the new Scene is loaded? Maybe call yield after you load the level so it waits for the result, and search afterwards.
