pull the rgb edges of an image outwards based on it's a control channel.
6.0, 6.1, 6.2, 6.3 or later
Linux, Mac, Windows

The edge colour is achieved by repeatedly unpremultiplying and blurring the image which helps get some sort of colour information into motion blurred keys for example:



The control matte os typically an eroded version of the alpha channel

This is an awesome gizmo!
Gives much cleaner result than any 3D renderer I've tried.

great tool, Frank! Did you see the Pixel Spread tool on Flame? Could you make something like that?

I ran into some problems getting this gizmo to work with 6.3v5. The parameters were getting confused when the script was saved, Nuke exited, and the script re-opened. Also, when I would try to copy to a group, I was getting the Gizmo constructor errors. I also couldn't copy and paste the Gizmo within the same script. I went ahead and re-built the gizmo so that it works with 6.3v5. If anyone else is having these issues besides me, I'd be happy to upload the new version.

Ned! I'm getting the same problem, please upload

Have you tried Nuke 6.3v6? Works fine for me in that version, maybe 6.3v5 had a bug? It's a very simple gizmo, no magic at all, so it'd be strange if the gizmo was to blame. What exactly does the error message say?

Hi Frank, how you been?

The show I am currently on is locked to 6.3v4. Bringing in gizmos are frowned upon, so I'm trying to bring them in as a group. When I open the gizmo in Nuke, then click on copy to group, I get this pop-up error:

Constructor for Gizmo Failed

Traceback (most recent call last):
File "", line 1, in
RuntimeError: Constructor for Gizmo failed

Nevermind, got it to work, thanks!

Hi Frank,

I got the same error. I'm on 6.3v5 on Linux. Vinh - did you use the one I emailed you, or did you get this one to work?
0 # Frank Rueter 2012-01-26 16:00
that's bizarre. can you guys please send this to the foundry support? sounds like a bug to me
0 # Vinh Nguyen 2012-01-27 10:37
I opened it through a text editor, changed the top line from gizmo to group, then copied and pasted all the text into the DAG. I was able to use Frank's version and it worked. Thanks guys.

This is such a useful gizmo, I have a small suggestion for an update, if you separated the slices into width and height so you could choose to only extend horizontally or vertically it would be handy, I've done this a few times by diving into the gizmo
0 # Frank Rueter 2017-01-08 21:06
Hi Andrew, do you mean just the blur controls or the actual slices as well?
0 # Andrew Rea 2017-01-12 18:44
I guess changing it to slice width and height is what I had done before
0 # Frank Rueter 2017-01-12 19:08
Ok. So you doubled the amount of built-in slices to drive horizontal and vertical independently I guess. I will have a look when i get time. If you already have a working solution feel free to email me and I can update the gizmo with it
