This might not be the most efficient, but we have this in place as part of
a larger archive script, happy to share:
import nuke
import os
import sys
def recursiveDependencies(n):
'''Given a node, find all upstream nodes. This works, but for moderately
complex nuke graphs it can take a long long time, eg 516 nodes found in
1418 seconds'''
thisDependencies = set(n.dependencies())
if not thisDependencies:
return set()
dependencyDependencies = set()
for nn in thisDependencies:
dependencyDependencies.update(recursiveDependencies(nn))
return thisDependencies.union(dependencyDependencies)
def findOutputs():
result = []
for n in nuke.allNodes():
if n.Class() in ["Write"]:
result.append(n)
return result
def findInputsFromOutputs():
result = set()
for n in findOutputs():
dependencies = recursiveDependencies(n)
for dependent in dependencies:
if dependent.Class() in ['Read','ReadGeo']:
result.add(os.path.dirname(nuke.filename(dependent)))
return list(result)
def printInputsFromOutputs():
print '\n'.join(findInputsFromOutputs())
def findInputs():
result = set()
for n in nuke.allNodes():
if n.Class() in ["Read", "ReadGeo"]:
result.add(os.path.dirname(nuke.filename(n)))
result = list(result)
result.sort()
return result
def printInputs():
print '\n'.join(findInputs())
