Hasta La Motion!

Im having a problem that seems like its got a straight answer but I couldnt find it.

Im sending nuke external information, like [argv 0] which is a filename and a path and put it into a variable ( file = str(‘[argv 0]’) ) but when ever I refer to it it gives back argv 0 and not the content of the string itself.

The read node im passing it to displays [argv 0 ] (and shows the correct picture ) but when I print the node’s property the ‘file’ attribute displays the full path and filename. I need to grab that data.

My leet haxxor python/nuke scripting skills are lacking, I hope there is a quick way to fix it. Any ideas?

THanks!

I’m writing an expression that will eventually be a button on the tools shelf in Nuke. This is what I have so far:

def VectorBlurToggle():
for node in nuke.allNodes(‘vectorBlurGizmo’):
if node.knob(‘disable’).value() :
node.knob(‘disable’).setValue(0)
else:
node.knob(‘disable’).setValue(1)

But what I want to do is instead of disabling the node entirely, I want to ad the expression $gui so that even if the node is disabled – the node will still render (using the studios rendering software).

Would be awesome if anyone could help me out with this.

There is always a thin transparent line in the alpha that reveals the background. Normaly the 2 images are premultiplied and I just put a merge in "over". Each image got its own alpha too.

how to solve it?
