Render Dependencies

The function GetSortedDependencyList() provides the information needed to obtain the names of any other nodes a Render node depends on. For example, the following script returns the names of a Render node’s dependencies, as a sequence:

def dependencyList(nodeName):
"""
Use GetSortedDependencyList to retrieve the entire dependency tree for a render node.
Each entry is ordered so that render nodes are sorted by number of dependencies, in descending order.
"""
# Get hold of the node and all of its dependencies as a sequence of dictionaries
node = NodegraphAPI.GetNode(nodeName)
info = FarmAPI.GetSortedDependencyList( [ node ] )
# Extract the 'deps' for each entry in the sequence
# to produce a flat list.
allDeps = [ dep for i in info for dep in i["deps"] ]
return allDeps
