Hi,
if I were to request the vector pass from 3d to plug into the kronos'
vector input, would it be a motion vector or velocity 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
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
in that case btw the red matte would be separate to the magenta, any overlap
would be black in the respective channels.

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
I was getting the same effects again today. Anyone have any clues?
