Most of the UE icons are in the engine install dir. Both PNG and SVG files are used. These icons can be used in custom editor modules, you probably should not use them in your game as they are unlikely to get packaged (not 100% sure about this, if you know better let me know)

How to find icon code names

  • Search for icon file name in engine code to find what the FSlateIcon is called
  • Not all icons are hardcoded into engine code - some use actor names. In this case, typical naming pattern is ClassIcon.ClassName, such as ClassIcon.Character.
