I don’t think so. I’ve tried other things in the past, and the only consistent
method is to avoid evaluating that tree at all.

Subject: [Nuke-users] Set merge node mask channel inside group
Hi,
Is it possible to change the state of a merge node mask input that is inside a
group/gizmo?
If I add an input node to merge mask input inside of group I get an error that
non-existent channel is used for mask.
For now I have a switch node with ![exists parent.input], but is there a more
elegant solution to this problem?
Here is the group I now use
Group {
inputs 3
}
Input {
inputs 0
name Mask
label "\[value number]"
xpos 160
ypos -181
number 2
}
Switch {
which {{"!\[exists parent.input2]" i}}
name Switch1
selected true
xpos 13
ypos -176
}
Input {
inputs 0
name A
label "\[value number]"
xpos -135
ypos -291
}
Input {
inputs 0
name B
label "\[value number]"
xpos 7
ypos -290
number 1
}
Merge2 {
inputs 2+1
operation over
bbox B
name Merge1
xpos -135
ypos -176
}
Output {
name Output1
xpos -135
ypos -91
}
end_group
Thanks for any help
