Technically speaking the keymix has no mask input. It has 3 normal
inputs where the third is called mask. That's why the knob is called
differently. You also don't know how the function works on gizmos that
also have no regular mask input but might have an input called mask
which is used for internal masking.

Hi Everyone,
Ean, just a quick update on your function. After using a part of it for
about a week, I ran into a small issue today while trying to show the
mask input of a keymix.
For some reason that node uses a knob called maskChannel instead of
maskChannelMask, making your function believe this node had no mask input.
It was easily fixed by adding a "or" to my if statement.
I'll let you know if I run into another issue.

Thanks a lot, that will probably work great.

Hey Erwan,
I wrote these functions a few years ago after I posted that to
the list:
https://gist.github.com/anonymous/a802f51391163a2bf0e3
Just call get_mask_input_index(node). I haven't run into any
node which returns a bad index for the mask, but if you do, let
me know. Yeah, I wish Nuke would give us something like
node.maskInput()
Cheers

Hello everybody,
I've been playing around with python and nuke for a little
while now and starting to get more comfortable, but I hit a
roadblock today.
I'm trying to find a way to identify the mask input from
other inputs.
So far I have that very dirty piece of code that works most
of the time, but not always:
node= nuke.selectedNode()
if node.Class() == 'Merge2':
maskInput= 2
else:
maxInputs= node.maxInputs()
if maxInputs> 1:
maskInput= maxInputs-1
else:
maskInput= None
Is there any function like node.mask() or something similar?
The closest I found online was this post from
2011:https://www.mail-archive.com/nuke-python@support.thefoundry.co.uk/msg00508.html
thanks
Erwan
