The Viewport is where you assemble the world and gameplay elements for your Fortnite Creative experience. Viewport controls and navigation are largely unchanged from Unreal Engine.

Important Viewport settings for UEFN are displayed in the table below.

Viewport Option	Optimal Setting	Reason
Field of View	90.0	If this setting is too low, your movement inside the viewport becomes restricted. If too high, you will zoom out from your build, and the build will look distorted.
Far View Plane	00.0	Setting this to zero shows an infinite view.
Screen Percentage	100	If the percentage setting is lower than 100, your build looks fuzzy. If the setting is high, the appearance of the build improves, but could use a lot of memory in Fortnite Creative.
Game View	Toggle On	Turns off all device visual properties for a runtime view of your project.
