Playtesting Your Island in Unreal Editor for Fortnite

As you create your game or experience in UEFN, it's a good idea to routinely playtest your project in Fortnite Creative to make sure the props, materials, and devices behave exactly as you intended when you set them up in the editor.

This is also a necessary step before publishing your project.

Playtesting in Unreal Editor for Fortnite (UEFN) is comparable to the Unreal Engine Play In Editor function, but instead of opening in the editor, your level is uploaded to the content service and run in an instance of the Fortnite game client.

UEFN also provides a way for you to playtest Verse devices and test your project on console.

When you're ready to test, press the Launch Session button.
