Control houdini from maya RPC

[graff]

Hi. I use rpc to create nodes in houdini from maya.

I dont undeerstand why this code work in houdini:

hObj = hou.node('/obj').createNode('geo', 'v')
hObj.moveToGoodPosition()
hObj.node('file1').destroy()
hImportFromMaya = hObj.createNode('file','importFromMaya')
hExportToMaya= hObj.createNode('file','exportToMaya')
hImportFromMaya.moveToGoodPosition()
hExportToMaya.moveToGoodPosition()
hExportToMaya.setFirstInput(hImportFromMaya)

and not work in maya. Maya code:

import houxmlrpc
hou = houxmlrpc.ServerProxy( 'http://localhost:8888' ).hou
 
hObj = hou.node('/obj').createNode('geo', 'v')
hObj.moveToGoodPosition()
hObj.node('file1').destroy()
hImportFromMaya = hObj.createNode('file','importFromMaya')
hExportToMaya= hObj.createNode('file','exportToMaya')
hImportFromMaya.moveToGoodPosition()
hExportToMaya.moveToGoodPosition()
hExportToMaya.setFirstInput(hImportFromMaya)
