And why a merge node block the concatenation like that :
set cut_paste_input [stack 0]
version 6.3 v4
CheckerBoard2 {
inputs 0
name CheckerBoard1
selected true
xpos -525
ypos -17
}
Transform {
scale 0.1
center {960 540}
name Transform1
selected true
xpos -525
ypos 77
}
Constant {
inputs 0
channels rgb
name Constant1
selected true
xpos -403
ypos -27
}
Merge2 {
inputs 2
name Merge1
selected true
xpos -403
ypos 77
}
Transform {
scale 10
center {960 540}
name Transform2
selected true
xpos -403
ypos 130
}
I think if I remember well in Fusion this setup works.
It would be great if you include this in Nuke.
