Hi everybody,
I am working on a python script that creates more than 25 read nodes with
approximately 30 timeOffset nodes connected to each of them. So I end up with a
script containing something like 1000 nodes. This could be extended later,
depending on the needs.
This is quite compute intensive to run. The main nuke thread/window freezes and
you don’t know how long you have to wait until it’s finished. I am trying to
put this in a separate thread with a status bar. The problem is that the
threaded way is even slower than without putting it in a separate thread. To
make it a bit clear, I wrote some python lines to demonstrate what I am trying
to do:
--------------------------------------------------------------------------------------------
import threading
### option 1: even slower than option 2 ###
def createBlurNodes():
task = nuke.ProgressTask("Create")
task.setMessage("Creating blur nodes")
for i in range(1000):
nuke.executeInMainThreadWithResult(nuke.createNode, args = ('Blur', '',
False))
task.setProgress(i/10)
threading.Thread(None, createBlurNodes).start()
### option 2: slow and I don't have visible feedback about the estimated
calculation time. Plus nuke is freezing for a couple of seconds, depending on
your machine specs. ###
for i in range(1000):
nuke.createNode('Blur', '', False)
--------------------------------------------------------------------------------------------
Maybe it’s slow because nuke.createNode is always running in the main thread?
Is this the correct way, or is there a better way to script this?
Thanks for the help in advance!
