Get Attribute

def nameToNodePlug( attrName, nodeObject ):
    depNodeFn = OpenMaya.MFnDependencyNode( nodeObject )
    attrObject = depNodeFn.attribute( attrName )
    plug = OpenMaya.MPlug( MObject, attrName )
    return plug

nodeObject = MObject type

MDagPath를 MObject type으로 변환하려면 MDagPath.node() Function을 사용.

dagPath = OpenMaya.MDagPath()
depFn = OpenMaya.MFnDependencyNode()
dagIt = OpenMaya.MItDag(OpenMaya.MItDag.kBreadthFirst, OpenMaya.MFn.kSurface)
while not dagIt.isDone():
    dagIt.getPath(dagPath)
    depFn.setObject(dagPath.node())
    arrtObject = depFn.attribute('intermediateObject')
    plug = OpenMaya.MPlug(dagPath.node(), arrtObject)
    print plug.asInt()
    dagIt.next()

뭐 대충 으런식으로 object shape attribute을 가져온다.
