Hi Nathan,
Thanks for your response.
The function I am calling does contain Nuke-specific code.
It reads in the sequences when they are finished rendering (simple loop with
create read node with some values set)
When I render locally and call it with the 'after render' function, it works
fine.
I tried the nuke.executeInMainThread() but to no avail.
def postRenderRead(writes, readnode, startframe, endframe):
for w in writes:
w['selected'].setValue(False)
read = nuke.createNode('Read')
read['file'].setValue(w['file'].getValue())
read['xpos'].setValue(w['xpos'].getValue())
read['ypos'].setValue(w['ypos'].getValue() + 180)
read['format'].setValue(readnode['format'].value())
read['colorspace'].setValue(w['colorspace'].value())
read['first'].setValue(startframe.value())
read['last'].setValue(endframe.value())
read['origfirst'].setValue(startframe.value())
read['origlast'].setValue(endframe.value())
read['selected'].setValue(True)
Thanks again,
Jack

Are you calling Nuke-specific code when it crashes? If so, you probably need to
call it using nuke.executeInMainThread(). Give that a try, and if it doesn’t
work, can you post an example of the types of calls you’re making when it
crashes?

Subject: [Nuke-python] using threading.Timer() to check if files exist
Hi,
I'm having a problem with the threading.Timer() function.
I've written a little class which runs after I've submitted a job to the farm.
It checks the directory of the write node(s) to see if the file exists / has
been rendered.
I run the timer to check it every 20 seconds until it completes. It check
nicely every 20 seconds and gives me correct feedback.
However, when it does complete, Nuke crashes and I get an error in the terminal
which includes:
"QObject::setParent" Cannot set parent, new parent is in a different thread"
"QObject::startTimer: QTimer can only be used with threads started with QThread
"Cannot queue arguments of type 'Animation_Event'"
"Make sure 'Animation_Event' is registered using qRegisterMetaType()"
These errors and crash only occur when the files have finished rendering and I
try to pass another function. Even if I use a try-except.
Here's a simplified snippet of my code:
class PostRender:
def __init__(self, writenodes, args):
get args
print some feedback
self.completed = []
def exists(self):
for w in writes:
if w in self.completed:
continue
if all(framerange in w exists):
print w + ' node has finished rendering'
self.completed.append(w)
else:
print w + ' node is still rendering'
self.wait()
def wait(self):
if len(writenodes) == len(self.completed):
#Crashes here and produces terminal errors
try:
print "Rendering complete"
do another function()
except:
return
else:
myTimer = threading.Timer(15, self.exists())
myTimer.start()
I'm new-ish to Python and have never used the threading module before.
I would be so grateful for any help / light-shedding on this topic.
Thanks,
Jack
