Davi Stein demonstrates a technique that she picked up while working on one of the Narnia films, showing how to create a heat distortion coming off a smoke plume in Nuke.
how to add distortion and heat haze in Nuke
Using Nuke’s roto / paint node and the noise node, for the composited heat distortion effect, Davi also adds some crepuscular rays as an added visual element, and provides a few techniques in this that can be used on their own in other projects.
