You somehow have duplicate material names in your Sketchup model. I don't know how this is even possible. I deleted all duplicate materials and it exported and rendered fine.
Do you know how the duplicate material names got in there?

Thanks a lot. It's a way I didn't think to explore. Material duplication... I even didn't think I made that. One more point I have to take care. It's a project I'm working on since a long time and without a real regularity. So I think the duplicated materials come from the inserted components.

Thanks again.
