Top down Camera

Hello,
So I have made a top down camera, using a pawn that is hidden in game and has the camera attached to it.
The problem I am having is that when I move the pawn it goes through the landscape, so if I make a tall hill I can’t get the camera to go up there.

This is how I move the pawn, so how can I make the pawn go up any hill no matter the incline instead of just passing through the landscape?
