Hi so i am Trying to render in maya a batch esentially via the sendCommans In Tops into python i keep getting a
Error:Node Reported failure for callback ‘onCookTask’

I have read throw https://www.sidefx.com/docs/houdini/tops/processors.html [www.sidefx.com]

And dont completely understand what to do to may code to make it work i have tried using the code they said in that but seems i am doing some thing Wrong asistance will be apreciated

This code is coppied that gives the erorr and if i try add it it still dosent work Please help also still very new to houini

Code :
import maya.cmds as cmds

def reportUserLog(*args):
message =
for arg in args:
message.append(str(arg))
message = ‘ ’.join(message)
mel.eval(r'print": %s\n";' % message)



#Load all the elembic plugins into maya
cmds.loadPlugin( ‘AbcExport.mll’ )
cmds.loadPlugin( ‘AbcImport.mll’ )
cmds.loadPlugin( ‘mtoa.mll’ )


#Find all the TransForms objects in the outliner in the top line of outliner
nodes = cmds.ls(type= ‘transform’)

#Gets the maya file location for us of this file so we can see what we need to export or how we need to use it
fileLoc = cmds.file(q = True, exn = True)
fileLocSplit = fileLoc.split('/')

#This will export what it needs from the lighting scene
if ‘render’ == fileLocSplit:
cmds.setAttr(“defaultRenderGlobals.currentRenderer”, “arnold”, type=“string”)
mel.eval('loadPreferredRenderGlobalsPreset(“arnold”);')
import maya.mel
cmds.workspace(dir = ‘O:/houdinie_pdg_test/work/houdini_test_proj/assets/imageSequence’)
cmds.setAttr('defaultRenderGlobals.imageFilePrefix', “O:/houdinie_pdg_test/work/houdini_test_proj/sh_002/render/maya/images/testingRen”, type = “string” )
mel.eval('mayaBatchRender();')

Is there anything in the Command Send work item log? Right click on work item dot -> Task Info. There may be a “Show Log” at the bottom.

Have you tried copy and pasting your code into the Maya script editor and evaluating it there?

The node it is running on is giving this log : Log not found

The top node that Reports everything back Is giving this :

The thing is I looked and the log i sent really saying eni thing in this matter because the command that is the problem is :mel.eval('mayaBatchRender();')

This command is a render script essentially so i need to tell Houdini to wait before it continues so let it wait for the render essentially

> so i need to tell Houdini to wait before it continues so let it wait for the render essentially

If `mayaBatchRender` is asynchronous you should wait in the python script until it's done if possible. Maybe you can hook up a post-render script in your Maya `renderGlobals` to notify you when it's done somehow (create a file / set some global variable etc).

Okay I Will Give that a Try Thank u for your suggestion haven't thought of that will get back to u if I Have more problems with this idea thank u again have a lovely Time Bye

I tried something like that really fast But node is still Having problems with onCOokTask so is there any documentation i can follow to figure out how the following commands gets implemented and testing them maybe they can work please
Your text to link here… [www.sidefx.com]

Because i Tried jsut taking the example they have there and trying yo tun it in a send command and a python command TOP network but no work so any more assistance will be appreciated and assistance given so far is already appreciated thank u

So to clearify im getting onCookTask error when i run : mel.eval('mayaBatchRender();')


and i Somehow need to tell Houdini this is a rendered inside the top Nodes

If you are using the Maya Command Chain block you should use the “Command Send” node to send a python script to Maya, not Python Processor with onCookTask. An example of this is found in $HFS/houdini/pdg/examples/top_mayapipeline

Can u Maybe send me a link To this sorry for the very long time to replay

Was busy with other parts of the program im trying to create

I am using the send command node its just its returning with :Node reported failure for callback “OnCookTask”

The example is in the Houdini install:
