Does the same 'blackness' happen in P4/PPP and P6..?

I had the same problem with lots of my props... they would render fine in P4/PPP but go black in P6 (fine in preview but black when rendered).

It was because some areas were single sided polys.. I had to remodel them to add a little thickness and then they all worked fine.
