nuke.render() can’t work!

I made a tool called Make Snapshots which worked pretty well.
And then I wanted to make a panel and put some button and label on it.
But this time I got some problems.The nuke.render() didn’t work.
So to find why I made a simply test and here’s my simplified script:


def startMakingSnaps():
    wt = nuke.selectedNode()
    nuke.render(, 1, 1)
 # create a panel class
 makeSnapsPanel = nukescripts.PythonPanel('Make Snapshots', 'makeSnaps')
 # Create knobs
 qtPathKnob = nuke.String_Knob('qtPath', 'QT Path:')
 snapsPathKnob = nuke.String_Knob('snapsPath', 'Snapshots Path:')
 fsOffsetKnob = nuke.String_Knob('fsOffset', 'Frames Offset:')
 makeSnapsKnob = nuke.PyScript_Knob('makeSnaps', 'Make Snapshots')

 # Add knobs

Then I got a panel and I clicked the button and a message window poped up to me which said that: Nothing is named "Write1".
But the write node’s name is really "Write1".
Then I run this line alone nuke.render(, 1, 1) and it worked.

I don’t know why.
Is there something different when putting function to the panel?

Stereoscopic 3d problem


I am attempting to do a stereoscopic animation and if you will look at the attached you can see the problem. I have lowered the interaxial separation down to 0.150 and you can still see problem and the belt buckle on her back. Please advise how to balance such projects and thank you very much.

Nuke cannot find ocula


I installed nuke and it worked fine. I then installed Ocula (for 3d work) and set the environment path as directed in the when I click on the Ocula icon inside Nuke it states..

"The procedure entry point could not be located in the dynamic link library DDImage.dll..then I close that and it opens to this message:

C:\Program Files\Common Files\Nuke\6.0\plugins\Ocula\2.0/O_Solver2_0.dll: The specified procedure could not be found.

OK Hide Details…
Which is very weird because that is where I placed the environment path and if I go to that area the dll is there.

Please advise and thank you.

.nk value into enumerationPulldown


I would like to display the recentFile name into my pulldown list.

This is what I have now:


enumerationPulldownl = "None nuke.recentFile(1) "

My problem is that is not the name of the comp but "nuke.recentFile(1)" into my pulldown list.

How can I transform this to have the name of the .nk ?

Thx, have a nice we.

Mask faloff bias

Somehow the mask falloff I make in Nuke feels biased very differently to what I am used to (as if masks had a different gamma or something), and frankly I do not like that very much. It seems as if the mask has a much brighter gamma (and a wider falloff). Is there a way to switch the mask colorspace to produce a more uniform edge, or is putting grade nodes inbetween the only option? I am working with log DPX files, default Nuke conversion to lin lite and sRGB viewer.
