Global Blutility Classes and the Blutility Shelf

Describes how to create global Blueprint utility classes, and how to call their functions from the Content Browser or from a customizable shelf.

Global Editor Utilities

The instructions on this page show you how to create and use a Global Editor Utility Blueprint class.

With typical Blueprint classes, you need to drop an instance of the Blueprint class into a Level in order to call its in-Editor functions and custom events, as described on the Scripting the Editor using Blueprints page. However, when you're creating utilities to extend the Editor, your scripts often don't have a dependency on a particular Level. For example, if you create a utility script that manipulates Assets in your Project's Content Browser, dropping an instance of that class into a Level doesn't help it do its job.

When you create a Global Editor Utility Blueprint class, you can call its in-Editor functions and custom events from the Content Browser, or from a new Blutility Shelf panel that you can customize to hold the Global Editor Utility classes you need.



  1. In the Content Browser, right-click the folder where you want to create your new Blueprint utility class, and choose Blueprints > Blutility from the contextual menu.
    Create new Blutility

  2. Choose the GlobalEditorUtilityBase as your parent class, and click Select.

  3. To edit the Blueprint graph for your new class, right-click it and choose Edit Blueprint from the contextual menu.

    Unlike typical Blueprints, double-clicking a Global Editor Utility class doesn't open its graph for editing. Instead, it opens a window that provides access to all functions and custom events in that Blueprint that have been marked with the Call in Editor setting.

  4. Either create a new function for your Blueprint class, or create a new Custom Event node in the Event Graph and enable its Call in Editor setting. From the output port of this function or custom event, create the Blueprint logic that you want your utility to carry out.
    For example, this graph iterates through each Asset in the Project and removes all collision shapes assigned to all Static Mesh Assets:

    Your Custom Event or function can't have any inputs. If it has any inputs, it won't be listed later when you open the Blutility from the Content Browser or from the Blutility Shelf.

  5. Save and Compile your Blueprint class.

End Result

Double-click your Blueprint class in the Content Browser to open a new window that lists all of the functions and Custom Events that have the Call In Editor setting enabled. Click any button to trigger the corresponding Blueprint graph you created in your Blutility class.


Instead of having to navigate to your Blutility classes in the Content Browser in order to launch your utility functions, you can access all of the Blutility classes you've created in the Blutility Shelf panel:

Blutility Shelf

Open this panel by choosing Window > Blutility Shelf from the main menu.
