Imported OBJ always renders as black

Hi, I recently started with Blender and now have come across a problem which googling didn’t fix so far. I have imported an OBJ file in my scene. To be more specific, it’s thisone.

I have a sun shining on my scene but whatever I do, the object remains black in the render preview window. I’ve deleted the existing UV mapping, deleted the materials, applied new UV mapping and materials but still. I am using the Cycles renderer. Do you have any idea what I can do?

Whenever an imported object looks wonky, this is your first point to check.

Yes, that did it. Thanks a lot! :slight_smile:
