Hi John,
No error message?
Someting callbacks need arguments like:
def getCameraCallback(*arg)
Just try this... :(
Hope this help
Regards,
Dorian

Hey there -
I'm trying to do something simple, but I'm getting a difference in
results when using a python button vs a callback.
Here's a simplified example:
def loadCamera():
n = nuke.thisNode()
n['read_from_file'].setValue(True)
n['file'].setValue('/path/to/fbxCamera.fbx')
n['fbx_take_name'].setValue('Take 001')
n['read_from_file'].setValue(False)
nuke.tprint('------Camera Loaded--------')
def getCameraCallback():
k = nuke.thisKnob()
n = nuke.thisNode()
if k and k.name <http://k.name>() == 'getCamera':
nuke.tprint('######## Loading Camera via callback ########')
loadCamera()
nuke.addKnobChanged(getCameraCallback)
camera = nuke.nodes.Camera2()
kgetCamera = nuke.PyScript_Knob('GetCamera', "Import Shot's Camera",
"loadCamera()")
camera.addKnob(kgetCamera)
kGetWithCallback= nuke.Boolean_Knob('getCamera', 'Get Camera')
camera.addKnob(kGetWithCallback)
Using the python button in the camera node after it's created always
pops up a dialog asking if I want to load the camera.
Good.
When I use the callback by checking the getCamera checkbox, I don't
get the dialog and the camera is not loaded.
Bad.
Even without an fbx to test with, just running the above code will
error the node with the button (since it tries to load a bad path),
but while the checkbox sets the file knob, it doesn't load the file. I
want to checkbox to reload the camera, as it's actually being used to
grab a different camera within the fbx file.
Is there a way around this?
Or is there a better way of writing the callback? Or is it a bug?
Cheers
