Quote - Yes, it helps. Have you tried to change the material to Matte and see if it works?

I just got home from work, so haven't done anything 'Dazzy' yet.

The affected surfaces all are some kind of (bog standard) metal, changing that might give kind of a clue.

Perhaps the smartest thing to do at this point is to start all over with a new, empty DAZ Studio project. There just might be some corrupted data lurking in the existing one some way or the other. Again, see what happens.

Cheers!
