Dropping Beneath Landscape

,

Unfortunately I have only one landscape and gizmo in the level…and I do not actually walk behind the landscape rather I move into or sink into a bit. is happening I figure because my imported landscape is not holding its detail or the detail is muted. Only by sculpting a bit of the landscape in a quad does the definition come back and I am able to move about normally.

I have uninstalled and reinstalled UE4 and still have the same issues.

Please see my Before and After Landscape pics:

After Landscape Sculpt:

Any help would be great on muting
