Re: [Nuke-users] Extract CMY Color id
Keyer is pretty much it. There are gizmos which just automate doing id channels on nukepedia and creativecrash but underneath they are all just keyers. For future though, get your cg guys to render multiple mattes to a single exr instead of using id's which just suck, especially pink that it likes to throw in there.

I just did this gizmo, you can pick any color choose if you want extract a
matte or apply the alpha on your picture with a premult if you want. Of
course I agree with Deke this way suck, an exr with matte is better but I
prefer several RGB matte pass.

Re: [Nuke-users] Extract CMY Color id
here's a solution based on colour expressions which pipes
(pure)secondary colors like magenta into the alpha. have look at the

not the most elegant solution tho' having secondary colours as IDs

in that case btw the red matte would be separate to the magenta, any overlap

Hi

my secondary colour node on nukepedia/creative crash - splits any image into

The output will show you any set of above ie rgb, cmy, bnw mapped into the
rgb channels.
So plug in your image choose cmy (as rgb) and in the rgb channels you will
have cyan magenta and yellow mapped to rgb respectively, so as long as its
pure cmy you get perfect mattes instantly

I just did this gizmo, you can pick any color choose if you want extract a

course I agree with Deke this way suck, an exr with matte is better but I
prefer several RGB matte pass.

it likes to throw in there. There are mel scripts for Mental Ray and
Vray which automate doing this.

Hi everyone,
I have a question maybe already ask (i checked before)
i'd like to know what is the best way to extract CMY to make a object
matte,
i guess that their is a better way than use keying nodes.
May someone can light me ?
i put in attachement an example.
Thanks.

Re: [Nuke-users] Extract CMY Color id
I've never quite seen how anything that crosses channels, if there's any
anti-aliasing involved, can not have issues...
If a red and a blue matte meet, and there is anti-aliasing along the edges,
causing a pixel to be (0.5, 0.0, 0.5), how is that different to a similar pixel
along an antialiased edge where a magenta matte meets black...

in that case btw the red matte would be separate to the magenta, any overlap
would be black in the respective channels.

This pulls perfect mattes even when you have a magenta and red matte
on top of each other or any other primary/secondary overlapping?

Hi
Shameless plug
my secondary colour node on nukepedia/creative crash - splits any image into
rgb, cmy and bnw (black neutral whites).
The output will show you any set of above ie rgb, cmy, bnw mapped into the
rgb channels.
So plug in your image choose cmy (as rgb) and in the rgb channels you will
have cyan magenta and yellow mapped to rgb respectively, so as long as its
pure cmy you get perfect mattes instantly

I just did this gizmo, you can pick any color choose if you want extract a
matte or apply the alpha on your picture with a premult if you want. Of
course I agree with Deke this way suck, an exr with matte is better but I
prefer several RGB matte pass.
