I think John specifically wanted to make this work in a terminal session.
And for the knobs to be populated correctly in a terminal session, you'll
need to use .forceValidate(), I believe.
John, can you post an example of what's not working for you?
The technique I mentioned before seems to work for me in a nuke -t session.
Ex:
>>> cam = nuke.createNode('Camera2', 'file /path/to/cam.fbx read_from_file
True')
# If you need to populate the fbx node names, then call cam.forceValidate()
here
# If you already know what they should be, then just set the values
>>> cam['fbx_take_name'].setValue('Take 001')
>>> cam['fbx_node_name'].setValue('camera1')
# At this point, the knobs won't be filled in, and will have the default
values as you described
>>> cam['focal'].value(), cam['transform'].value()
(50.0, {1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1}) # camera defafults
# But if you call cam.forceValidate(), it should populate them
>>> cam.forceValidate()
>>> cam['focal'].value(), cam['transform'].value()
(21.354494094848633, {1, 0, 0, 0, 0, 0.970598, -0.240708, 0, 0, 0.240708,
0.970598, 0, 0, 71.3, 287.5, 1})
Is the above not working for you? Maybe make sure you're asking for the
knob values on the right frame. Keep in mind that, on a terminal session,
you start on frame 0.
Hope that helps.
Cheers,
Ivan
