Thanks Rich,
so if i create a ContactSheet node and i want to set its xpos to the result of
the nodeList_center()
i can’t seem to figure that part out.
i’m creating the node this way.
def nodeList_center(nodeList=None):
'''Node placement function, from Drew Loveridge...'''
if nodeList == None:
nodeList=nuke.selectedNodes()
nNodes = len(nodeList)
x=0
y=0
for n in nodeList:
x += n.xpos()
for n in nodeList:
y += n.ypos()
try:
return [x/nNodes,y/nNodes]
except ZeroDivisionError:
return [0,0]
def createCS():
cs = nuke.createNode("ContactSheet”)
cs[‘gap’].setValue(20)
cs[‘center’].setValue(True)
cs.knob.(‘xpos’)setValue(nodeList_center) ### this part not working,
my syntax not great.
createCS()
Check out some of my work…
