Re: [Nuke-users] Extract CMY Color id
Yes that would create a semi magenta edge and would be extracted as such I
thought the mattes were cmy though?
I'll try it in a bit and check but it returns the colours split as described
along with overlap issues as you describe because they are in the image.

I've never quite seen how anything that crosses channels, if there's any

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...

splits into

secondary (cmy outside of rgb, bnw)

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.

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. 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.

[Nuke-users] ERROR: cannot set mapsize to 0 columns, 1 rows

[Nuke-users] Re: [ Nuke-users ] ERROR: cannot set mapsize to 0 columns, 1 rows
It means that the knob value got corrupted with an array instead of a single
value while saving.
I don't know how and why this happens, it is not restricted to user knobs only.
The only way to fix it is to open the script with a text editor search for the
knob and replace the { } with a correct value or delete the whole line.
Best regards,
Michael

good to know! but, wow that's weird. I'm not setting a mapsize knob anywhere -
what the heck is it for, anyway?
in fact, I deleted the mapsize line that was created with the gizmo and i think
that's when the error showed up.
great - 8 hours later and now I can't reproduce the error with or without that
line...
cheers!
