Hi there,
I can call HOM commands from the external python app use houxmlrpc server. For some strange reasons not is impossible to establish connections between nodes.


import houxmlrpc
s = houxmlrpc.ServerProxy('http://localhost:8888 [localhost]')
hou = s.hou

geo = hou.node('/obj').createNode('geo')
for child in geo.children():
child.destroy()
box = geo.createNode('box')
subd = geo.createNode('subdivide')

#subd.setFirstInput(box)


if I uncomment last line, this script will not work,
with this error:

Anyone know how I can fix it?
