Heres what I was putzing around with today. Wanted to make a more robust
context-aware node creation function. I'm no python expert so suggestions
and criticisms are welcome. I would like to find a better detection method
for 3d nodes, since the 'render_mode' knob is not in all 3d nodes, like
Lights.
## context aware node function
def contextAwareCreateNode(node2d=None, node3d=None, nodeDeep=None):
nodes = nuke.selectedNodes()
try:
if nodeDeep and selectedNodesDeep(nodes):
return nuke.createNode(nodeDeep)
elif node3d and selectedNodes3d(nodes):
return nuke.createNode(node3d)
else:
raise ValueError
except:
return nuke.createNode(node2d)
## Returns true if all selected nodes are Deep nodes
def selectedNodesDeep(nodes):
if not nodes:
nodes = nuke.selectedNodes()
for n in nodes:
try:
n.deepSampleCount(0,0)
ret = True
except(ValueError):
ret = False
break
return ret
## Returns true if all selected nodes are 3D nodes
def selectedNodes3d(nodes):
if not nodes:
nodes = nuke.selectedNodes()
for n in nodes:
try:
## Need to find better detection method for 3D nodes, this
method doesnt include Lights
n['render_mode'].getValue()
ret = True
except(ValueError):
ret = False
break
return ret
nuke.menu('Nodes').addCommand('Transform/Transform',
'contextAwareCreateNode(node2d=\'Transform\', node3d=\'TransformGeo\',
nodeDeep=\'DeepTransform\')', 't', icon="2D.png")
nuke.menu('Nodes').addCommand('Merge/Merge','contextAwareCreateNode(node2d=\'Merge\',
node3d=\'Scene\', nodeDeep=\'DeepMerge\')', 'm', icon="Merge.png")
nuke.menu('Nodes').addCommand('Color/ColorCorrect',
'contextAwareCreateNode(node2d=\'ColorCorrect\',
nodeDeep=\'DeepColorCorrect\')', 'c', icon="ColorCorrect.png")
nuke.menu('Nodes').addCommand('Image/Write',
'contextAwareCreateNode(node2d=\'Write\', nodeDeep=\'DeepWrite\')', 'w',
icon="Write.png")
