Definition

public sealed class PostProcessSceneAttribute : CallbackOrderAttribute

Remarks

A method with this attribute will also get called when entering Playmode, when SceneManager.LoadScene is called.
PostProcessSceneAttribute
has an option to provide an order index in the callback, starting at 0. This is useful if you have more than one OnPostprocessScene callback, and you would like them to be called in a certain order. Callbacks are called in order, starting at zero.
Note: If there are no new changes to the scene since the previous Player build, Unity doesn't rebuild the scene but uses cached Player data instead. In this case the 
PostProcessSceneAttribute
callback is not called. To ensure an unchanged scene rebuilds, you can either modify the scene or clear the build cache with BuildOptions.CleanBuildCache. Using EditorSceneManager.MarkSceneDirty alone is not sufficient to trigger the callback.
