Socketed to a mesh another meshes does not appear in Pawn (and in game)

Do you set the mesh of the static mesh component? Otherwise it would show empty.

I’ve added sockets in my main static mesh. And I’ve selected another meshes to be placed on those sockets. I’ve done it right in my mesh (not in pawn, which contains it).

The trouble:
I see attached meshes on my main mesh IN THE MESH
But I don’t see them in the Pawn, where my main mesh is added as StaticMesh component.
(And so in the game my main mesh is also naked).

Please give me advise, how to solve this issue.

Thanks.

I guess, I’ve figured out with this:
Slot in my main static mesh (where I selected another meshes) is named “PREVIEW Static Mesh”. So I think it designed only for preview.
