Hi guys,
I'm trying to build a gizmo with a mask input (as most of Nuke standard nodes).
I have two questions:
Is it possible to customise the 'mask' input to be at the side of the node
(just the small triangle instead of the top arrow)? And of course, how?
My other question is how to customise the a pulldown choice knob (channels) to
change dynamically as soon as you connect something into the 'mask' input. For
instance the same behaviour as the 'Grade' node, as soon as you plug the 'mask'
input into a roto node the 'mask' knob is activated and set as 'rgba.alpha' in
the pulldown choice.
I've copy a simple script containing the group, with the inputs and the 'mask'
knob.
Thanks for your help.
Cheers,
Victor
