thanks
Unfortunately, it's still not working as expected. Nuke is not hanging
anymore, but it only rendering the last frame of the requested range. So
I render 1-10 in the main write, I should be triggering 10 afterFrame
callback, rendering the frame just rendered to jpeg. But it will only
render frame 10.
Any clue why?? Here's my script now. The only difference from yours is
that I create a temp rean so that the jpeg is rendered from the dpx and
not the whole flow.
import threading
def renderAWrite(node, start, end):
nuke.executeInMainThread(nuke.execute, args=(node, start, end),
kwargs={'continueOnError': True})
def render_jpg():
f = nuke.frame()
read = nuke.createNode("Read",inpanel=False)
read['file'].setValue(nuke.thisNode()['file'].value())
read['first'].setValue(f)
read['last'].setValue(f)
w = nuke.createNode('Write', inpanel=False)
w['file'].setValue("path.%04d.jpg")
w.setInput(0, read)
t = threading.Thread(None, renderAWrite, args=(w, f, f))
t.start()
