Just to point it out; this is at least the third tool which I’ve seen do this sort of thing and possibly not the friendliest solution. If you are looking at it, do compare it to Hugh McDonald’s external control module – it answers more or less the same problem.

Sorry about all these comments, but I just figured out a round-about way to do this and wanted to share it in case anybody wanted the feature (its extremely round-about though). If you create a script using Francois’ code, then cat the getScript() to somefile.py, you will need to write an extra line at the end of somefile.py:
nuke.scriptSaveAs(‘path.nk’).

Then if you run:
/Applications/nuke/Nuke6.2v4.app/Nuke6.2v4 -nukex -V -t /PathTo/somefile.py

You get the automated .nk script, which you can create from shotgun, which will have all of your read/write nodes already in it!

I am both too busy and too new to both Nuke and Python to do this in a simpler/better fashion, but I wanted to contribute what I could. Again thanks soo much Francois for writing/sharing that amazing script!

Yes, I guess it could be modified to output a .nk file. It would be just a matter to add a function that tells Nuke to save. I don’t have time now to do it and I don’t know when I will have some time, but anyone with some python and Nuke knowledge could do it.

Awesome script! Thanks for putting this together Francois!!! There isn’t any way to make the script save out a .nk file is there?! Was hoping to use this to automate creation of .nk files with read/write nodes already prepared for artists.

How exactly do you set this up with python? I am on a mac running python 2.5.

Hi Francois,

Then i make comment this print line. i receive other error while run it again:

Traceback (most recent call last):
File “testNuke.py”, line 1, in
from nukeprocess import NukeProcess
File “D:\users\daniel\setting\Downloads\nuke\nukeprocess.py”, line 195
raise TypeError, “Unrecognized knob variable type: %s\n%s: %s” % (type(dKwar
gs[sKey], sKey, str(dKwargs[sKey])))
^
SyntaxError: invalid syntax

Any suggestion ? thanks you

Yeah, Nuke isn’t too helpful when frames are corrupted. The problem is that nukeprocess runs outside of Nuke, not inside it. So once Nuke is launched, my script can’t change it’s behavior. I should check if anything changed in 6.2, it seems to handle problem frames better. But that won’t happen anytime soon, I don’t even have time to install the latest version at the office.
Cheers.

Hi
I wan’t to use your script to check for corrupted frames from renderfarm – so I build a simple comp reading a frame and trying to save it as JPG.
For non-corrupted input frames it works OK, but with damaged one, script fails with following error, and, what more importand, freezes:

Nuke 6.1v1, 64 bit, built Jul 28 2010.

Any hints? Thanks
