Few days back I helped my friend in connecting the knobs of a gizmo to a panel that has same controls knobs, the only reason for such a requirement is that when the user selects or creates a node is selected, the properties panel gets replaced by the new knob properties, which was annoying for them as they had to modify settings from that particular knob again and again.

Here is a simplest way to check the input connections in nuke node This script will delete all unused read nodes from the comp.
In Nuke you can only move one node up or down using CTRL+ up arrow or down arrow either in up or down the nuke tree , to move multiple nodes selected you can used the the script below: Move the selected nodes up in tree calling the function below. to access these function from within nuke you can add menu to nuke like shown below: Download the whole script here.
So I worked out a solution to find a read node in the group, extract it and paste it outside the group and with still connected to original connection This script will read all the nodes to list that are inside the group "grp". Run this code given below, this will create scene node, scanline Render node, camera node and a constant node connect them together and connect the final output from the scanline Render, node to default viewer. You can add the below function to the init.py file or create a your own py file into which you place this code and then you import that file into init.py so as it can be called when a menu button is clicked from the interface. 1: def setupThreedNodes():2: mainCam = nuke.nodes.Camera(name="mainCamera",xpos=100,ypos=20) 3: scnlnRndr = nuke.nodes.ScanlineRender(name="ScanLineRender",xpos=250,ypos=35) 4: scNode = nuke.nodes.Scene(name = 'Scene',xpos=250,ypos=-100) 5: constNode = nuke.nodes.Constant(name="Temp_Constant",xpos=400,ypos = 10) 6: scnlnRndr.setInput(2, mainCam) 7: scnlnRndr.setInput(1,scNode) 8: scnlnRndr.setInput(0, constNode)9: defViewer = nuke.toNode("Viewer1") 10: defViewer.setInput(0,scnlnRndr)Add it as nuke button by adding the code below to the init.py file located in the .nuke directory. menu = nuke.menu('Nodes')menu.addCommand('3D/Setup 3D Nodes', 'setupThreedNodes()', 'alt + t') Fairly simple way to view an image sequence in Nuke, just execute the following line in command line: >Nuke6.1.exe -v "c:\\test_render_starfield\\starfield_v003_###.jpg" 1 90 This will launch Nuke with just its viewer i.e without node view or properties panel, and you can play the nuke sequence 
A 3d Artist might use fcheck that comes with maya, this is the same thing though some extra features.
Yesterday , I came up with method for assigning a list of items as value for a dictionary keys, so that every key has its own unique list. And all this is generated on the fly when nuke is run in terminal mode. 1: nuke.scriptOpen(target_file)2: allWriteNodes=nuke.allNodes("Write") 3: writeNodes=[] 4: wnodeData={} 5: attributes=[]6: for index,each in enumerate(allWriteNodes): 7: writeNodes.insert(index,each.name())8: for wNode in writeNodes: 9: for eachAttrib in ['first','last','file','file_type','channels','use_limit']: 10: wnodeData.setdefault(wNode,[]).append(nuke.toNode(wNode)[eachAttrib].value()) |
