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

here's
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
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.
set cut_paste_input [stack 0]
version 6.2 v2
here's a solution based on colour expressions which pipes
(pure)secondary colors like magenta into the alpha. have look at the
expressions (the '-r*g*b' bit is only to hold out the white in my
example)
not the most elegant solution tho' having secondary colours as IDs
set cut_paste_input
Merci Julien,
I'll try this at home in few minutes.
Maybe my 3d gay, sorry i mean guy like pink ;)

Try this...
set cut_paste_input [stack 0]
version 6.2 v2
Constant {
inputs 0
channels rgb
color {1 1 0 0}
name yellow
selected true
xpos 543
ypos -945
}
Roto {
output alpha

should do...
splits into
primary (rgb outside of cmy bnw)
secondary (cmy outside of rgb, bnw)
tertiary (bw (split into bnw) outside of rgb, cmy)
