“Tool Menus” are what Unreal calls most of the menus in the editor. These are almost all extensible via code.

How to find the UToolMenu name

To add custom entries to a menu (such as for Customizing the New Asset menu with Slate), you need to know the name of the menu.

  • Run the console command ToolMenus.Edit
  • This adds an entry into each menu where you can either immediately see the name of the menu, or you can click an edit icon to see the name of the menu.
