No idea what I'm looking at here. What does "Unwrapped with live turned on" mean?
You did not describe with a single word what the actual problem is. There is some strange looking reflection going on on this middle part of the propeller, that much I see. Question is about that? I don't know what this is supposed to look like, so I can't tell you what the problem could be.
Upload the geometry somewhere, I will take a look at it...
