MItDependencyGraph doesn't give all the nodes

[dav...@image-engine.com]

Hi Guys,

I run into an issue. The MItDependencyGraph doesn't give all the nodes.
I want the same result as using cmds.listHistory().
I tried many different settings, and flags but it didn't work.
Any idea?


import maya.api.OpenMaya as om2

cmds.polySphere()
cmds.polySphere()
cmds.blendShape('pSphere2', 'pSphere1')

sel = om2.MSelectionList()
sel.add('pSphereShape1')
mobj = sel.getDependNode(0)
it = om2.MItDependencyGraph(mobj, om2.MFn.kInvalid)
it.traversingOverWorldSpaceDependents = True
it.pruningOnFilter = False
fnNode = om2.MFnDependencyNode()

while not it.isDone():
currItem = it.currentNode()
fnNode.setObject(currItem)
print fnNode.name()
it.next()

# Result:
# pSphereShape1
# initialShadingGroup
# blendShape1Set
# tweakSet1
# Where is the blendshape, origin, etc node??
