Help with view distance.

Hi I recently made a scene for college and while im in Unreal Engine and moving around the scene the trees load but the distance view is very little basically i cant see all the trees only some that are near. Here is a video that shows my problem. I was wondering if there is anyway to change it so that I can see all the trees all the time.

note: The trees I used were from the open world demo collection.
