eFibonacciGlow v4.0

  • Quadratic, Fibonacci and Tribonacci fall-off
  • shrink black/white bug fixed
  • mask input added
  • minor bugs fixed

eFibonacciGlow is an exponential glow based upon Leonardo Fibonacci sequence of numbers. 


The exponential sequence is characterized by the fact that every number after the first two is the sum of the two preceding ones.

This is an alternative glow gizmo to Nuke's standard glow node.

Features included:

  • Choose channels
  • Glow size with exponential Faloff
  • Manipulate Input Luminance tolerance
  • Shrink Black/White
  • Effect on your footage / Effect only with possibility to merge over your footage
  • Mix with original

Very nice Gizmo, this Glow is way better than the Nuke standard.
But I think the last line for the menue.py should be:

eMenu.addCommand('eFibonacciGlow', lambda: nuke.createNode ('eFibonacciGlo w'), icon='eFibonacciGlow.png')

The one posted above gave me an error. And since you are not using any Nuke10 only Nodes (I guess), you can create the Gizmo for a lower version, 6 or 7 or something.
And you can take a look at the comp format, because right now the Gizmo forces the one set in the project settings, but it should adapt to the input by default :)

Hey Nikolai!
I'm glad you liked this Gizmo.
Thanks for the heads up! I think the problem was in the line "'nuke.createNo de('\eFibonacci Glow')'". There was an additional slash that shouldn't be there. I've corrected it in the readme.txt and updated a new 1.1 version. Everything works for me now.

The Gizmo is already working for lower version, that was a mistake during uploading! And about the comp format, the Gizmo already adapt to the input by default, there are no forces. Maybe if you are talking about the crop you could un-check "crop to format" to preserve bounding-box.

Thanks and keep compositing! ;)

Thanks for the Gizmo!

I've found it right when I was working on a project that needed a good deal of glow.

Happy compositing ;)

I use this all the time! However in v13 i can't add it to the menu.py, it crashes on boot.

Whats the proper syntax to add it? Thanks
