You probably know from some science fiction films that if a space ship or some kind of jet airplain flys by, engine flicker of flimmer can be seen, which dissorts the back of the space ship.
This effect can also be seen on roads ( on very hot days), where hot air moves up and creates a flimmery dissortion of the road.
I want to create a simmilar effect in Blender, where the hot gases from the space ships engines, dissort the back of it and create this flimmer or flicker.
It would be very helpful, if somebody would make suggestions on how it might be achieved.
Thanks in advance!
