Hi all.
I’m working on a shot setup/update script that essentially creates a noOp node with some knobs, including a maya render dir path, version, first frame, last frame, frame offset etc.
I got it all pretty much working, but the last thing I need to do is to hook all the selected read nodes to the noOp node via expressions controlling their filename (base path), first frame, last frame and frame offset.
Code:
def setup()
sn = nuke.selectedNodes()
rn = nuke.selectedNodes('Read')
first = 1
last = XXX
offset = XXX
...
...
...
for n in sn:
n.knob("selected").setValue(False) #deselect all nodes so the noOp gets created as a standalone node, not connected to anything
sourceNode = nuke.createNode("NoOp", "name asdf", inpanel = True)
#and then add knobs and assign values from input
#I have all my variables and the noOp node gets created with its knobs and values.
#All I need is to do THIS (badly described with pseudo code:
for n in rn:
n.['first].setValue(nuke.expression("sourceNode.first"))
n.['last].setValue(nuke.expression("sourceNode.last"))
n['frame_mode'].setValue(2) #This sets Read node's frame mode to 'Offset'
n['frame'].setValue(offset) #This assigns the value from user input
