for frame in range(1, 6):
    print("-" * 80)

批量修改某一类型节点参数

import NodegraphAPI

print(dir(NodegraphAPI))

nodes = NodegraphAPI.GetAllNodesByType("Alembic_In")

for node in nodes:
    print(node)
    parm = node.getParameter("abcAsset")
    oldPath = parm.getValue(0)
    newPath = oldPath.replace("D:/cache/", "Z:/cache/")
    parm.setValue(newPath, 0)

创建节点，自动组装

rootNode = NodegraphAPI.GetRootNode()

print(rootNode)

print(dir(rootNode))

primNode = NodegraphAPI.CreateNode("PrimitiveCreate", rootNode)

print(primNode)

mergeNode = NodegraphAPI.CreateNode("Merge", rootNode)

print(mergeNode)

print(dir(mergeNode))

print(help(mergeNode.addInputPort))

port = mergeNode.addInputPort("i11")

print(port)
print(dir(port))
print(dir(primNode))
port.connect(primNode.getOutputPorts()[0])

node = NodegraphAPI.GetNode("InChar")

print(node)

print(node.getBaseType())
print(node.getParameter("type").getValue(0))

print(mergeNode.getInputPorts())

import NodegraphAPI

node = NodegraphAPI.GetNode("Material_Stack")

print(type(node))
print(dir(node))

node.getChildNodes()

material = NodegraphAPI.CreateNode("Material", NodegraphAPI.GetRootNode())

node.buildChildNode(material)

print(dir(material))

print(dir(NodegraphAPI))

material = NodegraphAPI.CreateNode("Material")
material.setParent(NodegraphAPI.GetRootNode())

print(material)

print(NodegraphAPI.GetAllNodes())
