Tell me, how many times do you switch between the Nuke and Tractor windows every day?

If you are lazy like me and you want to check your renders immediately inside the Nuke UI, just use this Python script.

Go here to have more info and go deeper with this topic:


This is just an example of the interface. You can check the Active Jobs and Ready to start with the relative percentage. 



If any job is on pause, you can unpause it directly from the interface.




And last, but not least, Jobs with Error with the button to retry them. Really Handy!



And you will see the renders completed in the last hour



1. Unzip the archive

2. Drag and drop the folder in your .nuke folder

 #in your .nuke folder, path would be something like this:

 #Linux: /home/login name/.nuke
 #Mac OS X: /Users/login name/.nuke
 #Windows: drive letter:\Users\user name\.nuke


3. Add this code to your file and of course modify the Tractor_path (do not change the file in the folder Tractor)

 Tractor_path = '/Users/yourPath/.nuke/Tractor'


4. Open the file and find this code:

     SIMTRACKER = {'user': 'insert_here_your_username', 'password': 'insert_here_your_password!'}

Insert your username and password that you use to log into Tractor and save the file. In this case, remember to delete this line if you want to send the files to your colleagues :)


5. Run Nuke


You can have problem to find the Tractor path. In case, please copy and paste this code to the

tractor_location = '/opt/pixar/Tractor-2.2'

sys_paths = ['lib/', 'lib/python2.7', 'lib/python2.7/plat-linux2',

'lib/python2.7/lib-tk', 'lib/python2.7/lib-old', 'lib/python2.7/lib-dynload',


for p in sys_paths:

   path = os.path.join(tractor_location, p)

if path not in sys_paths:



Thanks to Attila Gasparetz and his Pipe department for the advice!
