Shadows Missing - where did they go ??

here is a picture of a FBX model i am trying to import (the orange one). As you can see, it has no shadows, whereas the meshes in the background have shadows. It is a procedural OBJ file, with UV map added and then converted with FXB converter.

What is italt text missing?

Thanks!

The model looks as if it is lacking any normals as its totally flat.
Check if it has normals and if you are unsure, use the Generate possibility in the mesh import settings
