How do I set up a PhysX Lab .apb file to cast shadows?

Hello,

I just imported a destructible mesh into UE4 which I fractured in PhysX Lab, everything works the way I want it to work however, it is not casting (and I believe receiving) any shadows. Is this a known “bug” or did I just forget something to turn on/off for the mesh?

Hope anyone can help me.

Cheers.
