Why datasmith is not importing materials?

Im importing a Rhino file using datasmith and it imports the model and materials but the materials are empty. The materials I used in vray are there but It display a gray checkerboard. It worked the first time I used datasmith but not anymore.
What I can do to make it work?

Thank you.

That link is broken.

and I have the same situation. Coming from 3D MAX (2018) using Datasmith ( for UE 4.22)… materials in UE don’t show up… folder isn’t even created
