Datasmith shadows and lightmaps not working

Development Rendering

Good day

I am very new to UE4.
I want to create some renderings of solidworks models I created. But when I import them using datasmith there are no shadows. I have googled and search forums and it seems like the problem is with the UV maps that datasmith creates. But when I try to generate new UV lightmaps the problem doesn’t go away.
If there is anyway at all that I can get datasmith to work please let me know.
Perhaps the issue is with my workflow?

Thanks

Even if someone could suggest a way to import my cad models without datasmith I would do that.
