You are getting an error because you are trying to set off the proxy
render in the main thread while the main render is still running in it.
So you need to launch the proxy render in a background thread BUT -
WARNING!!!!"
As the proxy render finishes it will again execute the afterFrame
callback, toggling back to full res mode and rendering that again, and
os forth. If you do this in a background thread every time you will
spawn background nuke renders till the cows come home.
So you need to make sure that when the callback is run and nuke is
already in proxy mode, just return out of it to avoid an infinite render
loop.
Since you need to run a background thread, you also need to make sure
that your callback is picked up by the init.py so it's available for the
command line render.
Here is an example - (not thoroughly tested!):

I'm trying to render both a full-res and a proxy-res file in one go by
flipping from full res mode to proxy mode during a render. However,
I'm having two problems: 1) it seems like Nuke doesn't want to stay in
proxy mode if it's switched on while a render is taking place. And 2)
I'm getting a RuntimeError when trying to execute the write node from
the afterFrameRender callback.
It's this code:
def toggleProxyAndRender(node):
proxy = nuke.root().knob('proxy').value()
print proxy
nuke.root().knob('proxy').setValue(not proxy)
proxy = nuke.root().knob('proxy').value()
print proxy
nuke.execute(node, 1, 1)
With this setup:
set cut_paste_input [stack 0]
version 7.0 v2
CheckerBoard2 {
inputs 0
name CheckerBoard1
selected true
xpos -260
ypos -249
}
Write {
file /tmp/imageFull.jpg
proxy /tmp/imageProxy.jpg
file_type jpeg
checkHashOnRead false
version 30
afterFrameRender toggleProxyAndRender(nuke.thisNode())
name Write1
selected true
xpos -260
ypos -136
}
I get this behavior in 6.3v6 and 7.0v2.
Am I going about this the wrong way?
