A more organic glow than Nuke's built-in filter.
6.3 or later
Linux, Mac, Windows
20 Jul 2017

Simple setup of blur nodes with exponentially increasing size, added back to the input successively. expoglow features a pre- and post-grade section, colour shift settings and a mask input that behaves the way it should – masking the input, not the glow itself.

Should work in all versions and across OS, please let me know if it doesn't.

Update 1.1: fixed a bug that would introduce alpha.red / alpha.green channels in some cases.

Update 1.2: took out some internal stuff that wasn't needed. And a viewer, for which I apologize sencerely. Stupid mistake.

Update 1.3: improved internal merge and crop ops for performance and stability. changed the 'crop to' modes to make better sense (I hope). added 'mix luminance' controls to the post-grade section.

Update 1.4: fixed a hickup with the last file. will have to work on my quality assurance...

Perfect, exactly what I was looking for! I love the color shift options. :-) This is so simple you think it would be included in Nuke, but alas it is not. Surprisingly it took me quite a bit of searching to finally find this tool - I was one page away from just making it myself.

Thanks Spencer, glad you like it. :-) (I wish Nukepedia had shot me a mail about your comment, I might have replied a tad earlier. ;-) )

we always do automatically (which is how I just got notified of your post). It might have got stuck in your spam filter, so maybe white list nukepedia as a sender.

This one came through alright. :-) I just did a search through my folders and couldn't find this particular mail, although I did get notified about comments before. Weird. Oh well, never mind, what and wherever the hickup was, it seems fixed now.

it is the best glow for nuke! thank you so much.

but making is not working. Is there way to use the masking?

Hey Sophia, thanks for your nice comment! :-)
Masking should work alright, but I didn't put a callback on the knob, so you'll have to manually activate the check box next to the mask channel dropdown. Let me know if that fixes your problem. Cheers!
