Hey AJQuick-
Looking at your screenshot it appears that you are attempting to do a trace from an actor/object that is under the landscape, back to the landscape itself. Can you confirm if this is what you mean? If this is the case the behavior you’re seeing is expected as a landscape is a one sided object and does not have collision from below. It does however sound as though you were able to find a solution to work the way you want. If so, feel free to mark your answer as accepted.
