Is there a way to automatically set selected nodes to use a specific vector input?

E.g. If you have a larger node setup with a lot of texture nodes, it can be a pain to go back through and connect each texture node's vector input to a texture coordinate node individually.

Is there a way to automate this process?

Add a Reroute node with the desired value and select it. Then, you can use this script.

# First, define some stuff
# mat: the material; tree: the node tree; nodes: the node list
mat = bpy.data.materials['Material Name'] # or index
tree = mat.node_tree
nodes = tree.nodes

# We'll find the source node and store it in src
src_socket = None
if nodes.active:
  if len(nodes.active.outputs) == 1:
    src_socket = nodes.active.outputs[0]

if src_socket is not None:                       # only work if node found
  for node in nodes:                             # check each node
    if node.type.startswith('TEX'):              # only operate on textures
      for input in node.inputs:                  # check each input
        if input.type == 'VECTOR':               # only operate on vectors
          tree.links.new(src_socket, input)      # set up the link
          break                                  # only do the first vector
else:                                            # fail if no valid select
  print('No single-output node selected')

Tested on Blender v2.69 r60995.

  • $\begingroup$ Instead of that first loop to assign src to the node, could you instead use src = nodes['CopyVector']? (using a try/except incase it doesn't exist) $\endgroup$ – Greg Zaal Nov 12 '13 at 5:54
  • $\begingroup$ @GregZaal Good point, thanks - but see my edit; this is easier anyway. $\endgroup$ – wchargin Nov 12 '13 at 5:54
  • $\begingroup$ Well there's always a better solution isn't there ;) $\endgroup$ – Greg Zaal Nov 12 '13 at 5:55
  • $\begingroup$ There is a reference to an undefined variable src on line 13. I changed it to src_socket and it worked beautifully. Also, if anyone copy/pastes this they won't import bpy, you might want to add that. Thanks :) $\endgroup$ – gandalf3 Nov 13 '13 at 8:07
  • $\begingroup$ @gandalf3 fix'd. $\endgroup$ – wchargin Nov 16 '13 at 1:00
