Perfect, thank you!
About the Turbine texture set, mine looks much rougher than the original that is shinny bright.
I don't know wich one is better.
Perhaps something like this:
newmtl turbine_hull
Ka 0.05 0.05 0.05
Kd 0.375 0.375 0.375
Ks 0.375 0.375 0.375
#Ka 0.205 0.205 0.205
#Kd 0.975 0.975 0.975
#Ks 1 1 1
#map_Kd turbine_hull_color.png
map_bump turbine_hull_bump.png

BTW, just look at the "turbine_hull" alone to see the AO i have done (that was another great enhancement).
