I love helicopters and this one is one of i prefer, because it's a big one and complicated too.
I found a picture of side and another perspective view of the helicopter and i started to modeling with polygons mothed. I used mental ray render with phisical sky and render passes like, cor, occ, dof and i don't no how the name of "motor hot", sorry. I really love this job and i hope to make more helicopters.
i hope you like it
Thanks
