Apparently custom gizmos have some trouble on our farm. A nice feature would be to use the “Copy Gizmo to Group” Option in nuke to convert all the gizmos to groups before submission. That way it would be a little more resilient a little less dependent on studio wide configurations.
Sounds handy. I’ll add it to our ever-growing wishlist

If you open the .gizmo files and change the line at the top from “Gizmo {” to “Group {” they will work fine through deadline.
This does mean they are open groups in Nuke, but thats never normally a problem for me
