Add Nodes Inside A Group With Python

As I only have Nuke NC at home I can’t export a gizmo that I can share with other people, so I decided I had to try and create the whole node programmatically, by building it with my Python script. To do that I have to be able to create a group and then create nodes inside the group. To do that you have to open the group with .begin(), then create any nodes that you want inside the group, and then close it with .end().

Here is an example where I create a group, then add an input node, then a corner pin, a crop and finally an output node before I close the group.

Thanks to Ben McEwan again for this one.

g = nuke.createNode('Group')
