createNode is not working.

Running the python code as OTL (geometry operator type with python)

 

Its getting this error --> 

Traceback (most recent call last):

OperationFailed: The attempted operation failed.

This node cannot contain other nodes

 

 

Here is the code..

# This code is called when instances of this SOP cook.
node = hou.pwd()
geo = node.geometry()

# create a temporary ROP node 
fbx_rop = hou.node('/obj/pyro_import1/OUT').createNode('filmboxfbx') 


# set the output path to whereever you want the file to go 
fbx_rop.parm('sopoutput').set("$TEMP/out.fbx") 


# Path to object hierarchy you want to export 
obj_path = hou.node('/obj/pyro_import1/OUT').path() 
fbx_rop.parm('startnode').set(obj_path) 


# Now just run the "render" method on the node, and delete the ROP 
fbx_rop.render() 
fbx_rop.destroy()

Isn't that /obj/pyro_import/OUT a Null SOP, which in fact can't contain nodes?  At least I would assume that since 'OUT' as usually reserved for Nulls...

@symek

 

Actually, it is not, it has all the point attributes and geo that I want to export..

Understood, but it still might be a Null SOP, albeit: 

hou.node('/obj/pyro_import1/OUT').createNode('filmboxfbx')

above line attempts to create a filmboxfbx ROP inside .../OUT node, which doesn't make sense, unless OUT it's a ropnet node. Is it? (your error output suggests it is not).

 

Assuming filmboxfbx is a ROP type (can't check now, no Houdini around, sorry), you would like to do something like:

geometry_to_export = hou.node("/obj/pyro_import/OUT")
parent = geoemtry_to_export.parent()
ropnet = parent.createNode("ropnet")
ropnet.createNode("filmboxfbx") ...

more or less...
