Make your breakdowns easier with this tool. Only select one node and press '[ ' (open bracket). This python script will save the frame where you are in the same place of your .nk script. It's auto numerable to keep the sequence easy to follow. And the filename will get the selected node's name. And also will create a Dot to mark the rendered nodes.
To install, just edit your menu.py with this text:
and copy the FrameBreakdown.py to your .nuke folder.
You can find your .nuke folder at:
Linux: /home/login name/.nuke
macOS: /Users/login name/.nuke
Windows: drive letter:\Users\user name\.nuke
