Static mesh imported from Blender has two materials in UE4, although just one material is defined in Blender

I’ve modeled a static mesh in Blender, created one material and assigned all the vertices to it:

I’ve exported the selected mesh in Blender to fbx.
In UE4, the imported mesh has two materials:

How do I get rid of the second material in Blender? I want the mesh just to have one material.

If you import the model back in to blender from the export you made does it have 2 materials?

no, just one

I can only think you are exporting more then one mesh?

I have used blender for all my importing and always have the right number of materials.

I think by default blender exports your whole scene. I have it setup in the FBX exporter to only export selected objects. Try this?

I’ve solved it. I’ve exported the mesh from Blender to fbx, then imported the fbx again to blender. Then I exported this mesh again to fbx. When I import this mesh to UE4, it just has one material.
I don’t know why, but it worked.
