unity5.4 Asynchronous loading

To upgrade the project Unity, found in 4.x version with Appliacation.LoadLevelAsync (string) can be loaded into the resource load, replaced by unity5.4, because for the new api, use SceneManager.LoadLevelAsync (string), but the return value It is empty, which big god can help analysis, what is the reason ah?[88938-qq图片20170227172519.png|88938]

If you want to load a scene from an AssetBundle you should be able to use AssetBundle.GetAllScenePaths to get an asset path to the scenes that are inside an AssetBundle. That scene path should work with SceneManager.LoadLevelAsync. Though I haven’t tried it yet.
