Glad you like it guys, I have put quite some time into it so it's good to hear some good words

otakar: Yes, I hope so!
Kadri: Actually, the mountain is quite a bit larger than real-world mountains, nice catch!
Bjur: Basically, we were looking for an appropriate background where we were able to show two planes and then ended up using this image. We usually show only one airplane, this time we needed to show two of them.
Oshyan: This is something I wanted to test to have an idea of how the plane would look with proper lighting in Terragen, but I haven't done so. If time allows, I'll import some of the fuselage into Terragen to see how it looks up there. Still, the ability to render HDR spherical environments in Terragen does help a lot (hint: it would be awesome to have this in Terragen out of the box

).
TheBadger: Brazil is a renderer plugin for 3dsmax, comparable to Vray. It's not available anymore and its development has been stopped quite some time ago, unfortunately.
