Mesh Terrain: Converting to Static Mesh results in flat geometry

Hi, I’m using Unreal Engine 5.8 and trying out the new experimental Mesh Terrain / MeshPartition system. I have a Mesh Terrain with mountains, and it looks correct in the viewport.

I’m trying to export the actual terrain geometry to FBX so I can edit it in Blender. I tried using Modeling Mode → Convert to convert the MeshPartition into a Static Mesh.

However, the resulting Static Mesh is almost completely flat. The mountains/height information are missing. The original Mesh Terrain looks like this

After using Modeling Mode → Convert, the resulting Static Mesh looks like this:

My questions are:

1. Why does Modeling Mode → Convert produce a flat Static Mesh?

2. Is there a correct way to convert/export the actual Mesh Terrain geometry, including the mountain height, to a Static Mesh?

3. What is the recommended workflow to export Mesh Terrain to FBX and then use it in Blender?

Basically, I want to do: Mesh Terrain →

Actual terrain geometry with mountains → Static Mesh → FBX → Blender Thanks!
