Convert Landscape to Static Mesh While Retaining Height Map Material

I’m trying to convert the landscape in to a static mesh, but using UE’s “Convert “Landscape” to static mesh” just end up with this weird chunk of grass. I tried exporting and reimporting the landscape as both a .fbx and an .obj, but both doesn’t export the material along with the landscape.

Is there anyway to convert the landscape to a static mesh while retaining the height map material that was painted on to the landscape?

I have the same problem
