Sorry for posting this model again here, I hope it is ok.
Finally I found some time to do a final rendering which really fits to the idea I had in my head for a long time: Warming up the engines with a lot of dust and heatwaves

All is done with 3ds max 9 (modeling was done in 8) and finalrender Stage-1. I used raytraced depth of field, 3D motion blur for the rotors + particles and micro-triangle-displacement for the ground.

Here´s a highres version of the rendering:



Maybe an animation of this shot follows but first I have to dig through TP2.5 again (and hopefully have the time).

I hope you like it
Cheers
