HammerHorror, Thanks! David, yes the steam is VERY 2D (and sloppy quick, as I just wanted an effect). The whole thing is rigged (ie treads, guns, turrets), so at some point I will experiment with either emitters or fluid containers (I have emitters for smoke, just haven't had time to play with the settings for leaking steam). As for camera, I do have a few other angles, but just recently figured out a few lens/lighting techniques which I will try. If you can suggest anything specific, I'm all ears...!
