Looks like a clipping plane problem or like the camera in the scene capture cuts the ground on the Z-axis (I presume its a top down view o f the world.)
Play around with the clipping plane settings. They can be extended in the scene capture component.
Second - Attach the scene capture component to something
Either you attach a scene capture actor or you can add a scene capture component to you pawn/game-camera. This way will allow you to always have a constant height from the ground. This will only work if your character/pawn can’t fly.
Or you can let the scene capture component in runtime place it self X number of units above the Landscape or floor.
I hope I gave you some ideas how to crack this, good luck
