I am going to take your suggestion about the polygon count Jim and I am going to rebuild the prop. I was fooling around last night and found out that the third and middle cylinder really did not make that much difference to the over all visual out come - after making few adjustments to the trans map - no difference at all, but an improvment - all ready one third less polys. By the way they are really not cylinders they act as such visually, but more a less look like triangular fish sticks one inside of each other. With each ones end and corner edges with a clear trans material and mapped only in the middle planes. Thank you for your time and input, you have been most helpful Dale MacMullin
