Darren,
Sorry, I should have added a usage hint…
ListOfNodes = nuke.selectedNodes() #Make a list of node objects...
center = nodeList_center(ListOfNodes) #Find the center of the list of nodes…
Returns [x, y]
cs = nuke.createNode("ContactSheet”) #Create your new node...
cs.setXYpos(center[0], center[1]) #Use the setXYpos method and set
the x, y values of your new node to the values you got above…
Does that make sense…?
