Yes, I don't think the problem is not MoI, and I am sure Something is happening with the export from Maya (2009). I will have to investigate further over at the Octane forum (as I said before, it renders fine in mental ray). Octane is just very picky about things. I was looking at the section where they have screenshots of all the different 3d apps export settings, but no Maya (am I an odd-ball using Maya? How dare I?). Anyway, off to continue my hunt for an answer/solution. Nice renders PHILBO!
