Yep, threading!
Something like this untested/pseudo-code:
import threading
def callback_render_done(jobid):
"""Function is executed in main thread, so can alter nodes etc
"""
print "Job ID is done!"
for w in nuke.allNodes("Write"):
w['label'].setValue("blah...")
class FarmMonitor(threading.Thread):
def __init__(self, jobid):
"""Initialise thread, then store the jobid for use later
"""
super(FarmMonitor, self).__init__()
self.daemon = True # Don't prevent Nuke from closing
self.jobid = jobid
def run(self):
"""The main thread function. Checks if the job is complete,
then runs the callback when it is done
"""
while True:
if is_render_done(self.jobid):
nuke.executeInMainThread(callback_render_done, self.jobid)
return # Ends thread
else:
time.sleep(1) # wait before checking again
mon = FarmMonitor(1234)
mon.start()
Same idea applies to updating a PythonPanel, or nuke.ProgressTask()
instance - showing farm-render progress via ProgressTask's is something
I've been meaning to play with for a while..
