	<brief_description>
		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:
		[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 GodotObject _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);
					}
				}
			}
		}
