A simple halation script that now uses Jed's OpticalConvolve, which is a faster FFT solution compared to the slow and buggy one I used in previous versions. 

A lite version is also available, which does not require the previous kernel in order to function. Nevertheless one is included this time; incase it's still desired.

I would greatly appreciate feedback, doesn't have to be technical could be about the design of the interface and what to change in order for a smoother workflow.

version 1.2 is on its way. Added more advanced controls for a better result and will be adding new methods aswell.

Its a rly cool solution and clean ui :) thx

Using OCIO and ACES1.1 the color transforms break because they cannot find the default REDlog colorspace. Otherwise a very nicely laid out gizmo! great job!

Thank you! Ah this seems to be a problem because ACES doesn't include some of the color spaces from nuke's default ocio config. I'll try to see what I can do. Thanks for the heads up.

New minor update is out now. Still haven't quite managed to fix this issue but I've made it so the screen method works for now only. Read the update changelog for more information.

Nice gizmo.
Please convert AlphaEdge into the group, so it will work on other machines. At the moment it will show an error if there is no AlphaEdge gizmo install.
+1 # silly calvin 2020-02-07 16:06
Completely forgot about that. I'll update the gizmo to the site very soon.

is just for Nuke 12?
+1 # silly calvin 2020-02-07 18:21
It may work with an earlier version but I'm not sure, you'll have to test for yourself.

This tool gives a nice effect, I like it a lot. But in my opinion it's not good and useful to put grain into this effect. Since many artists will prefer their own way to adding grain this will be useless function which will have his own separate tab called F_ReGrain

Thank you, the grain I added has an OFF and ON button if you wish to not use it and it's OFF by default. I have it as a separate tab for the reason that it won't take up the screen as much as it will be used if that makes sense. The grain will also only affect the halation effect and not the whole comp.

I migrated the Regrain node into my gizmo so it would be easier to match an already comped plate with grain. This is by no means the perfect way of doing it but it will easily solve that issue I believe.

doesnt work with Nuke 11

Have you made sure to read the README.txt file? The nuke11 version of it works fine on my system when I last tried it. (Nuke11.3v6)

Hey! Incredible filter. I love its effect. Unfortunately, the convolution method looks like it doesn't work with proxies? The effect becomes incredibly exaggerated at any proxy scale. I prefer working with proxies since I have other quite heavy nodes in my pipeline, so it would be nice to see a fix. Nuke 12.2v3

Thanks I appreciate it and sorry for the late respond!

Sadly this issue has something to do with the 1st kernel using a heavy flare which somehow gets a little too excited when used in proxy mode like you described.

In the meantime I would suggest using the 2nd kernel, not much is different in 1:1 scale because it's mostly the same but doesn't use a strong flare and on proxy mode the issue is resolved.

I'll try and solve this issue properly someday because the problem was more or less due to how buggy the convolution method is in general so it's hard to find a good balance.

Anways Merry Christmas!

I would like to apply it to ACES "syntheticChart .01.exr", but if I apply it to a linear image, doesn't it look broken in OpticalConvolve ?
