		Post-processes scenes after import.
	</brief_description>
	<description>
		Imported scenes can be automatically modified right after import by setting their [b]Custom Script[/b] Import property to a [code]tool[/code] script that inherits from this class.
		The [method _post_import] callback receives the imported scene's root node and returns the modified version of the scene. Usage example:
		[codeblocks]
		[gdscript]
		@tool # Needed so it runs in editor.
		extends EditorScenePostImport
		# This sample changes all node names.
		# Called right after the scene is imported and gets the root node.
		func _post_import(scene):
		    # Change all node names to "modified_[oldnodename]"
		    iterate(scene)
		    return scene # Remember to return the imported scene
		func iterate(node):
		    if node != null:
		        node.name = "modified_" + node.name
		        for child in node.get_children():
		            iterate(child)
		[/gdscript]
		[csharp]
		using Godot;

		// This sample changes all node names.
		// Called right after the scene is imported and gets the root node.
		[Tool]
		public partial class NodeRenamer : EditorScenePostImport
		{
		    public override Object _PostImport(Node scene)
		    {
		        // Change all node names to "modified_[oldnodename]"
		        Iterate(scene);
		        return scene; // Remember to return the imported scene
		    }
		    public void Iterate(Node node)
		    {
		        if (node != null)
		        {
		            node.Name = "modified_" + node.Name;
		            foreach (Node child in node.GetChildren())
		            {
		                Iterate(child);
		            }
		        }
		    }
		}
