what is the correct way of exporting meshes from blender to unreal?

](filedata/fetch?id=1812454&d=1600337668) Hi, i just saw a really nice asset pack and I downloaded but it was a blend file so I opened it in blender and exported it from there(with the pipeline add on that sends meshes directly to unreal)
but the problem is the materials are not applied correctly and they are all pure white.
the second problem is that meshes are exported separately and not in 1 piece how do I fix this? I haven’t really worked with blender that much

As far as I know Material transfer between Blender and Unreal is not supported. So you have to manually import the textures and set up the material in UE.
And to import the meshes as 1 connected mesh you have to select a checkbox during import.
