I've received a lot of requests asking for copies of my gizmos and some tips on how to use them. I decided the best solution was to put together a demo script showing everything in action so you can have a play in your own time.
Download the Nuke script here.
The script is a simple composite of some swirling embers (seen in the clip above), have fun moving sliders to see what makes everything tick!

The spectralize setup doesn't work with the latest version of nuke?
