Deadline rendering-error: Bad parent found (parent is not a network)

[vanished]

Hi,

I'm trying to get Houdini 18 + Vray to work with network rendering through Deadline.
My setup is one workstation and 4 rendernodes.

A simple test-scene is successfully network-rendering on 2 of 4 rendernodes. the 2 other nodes and my workstation are failing and giving this error:

=======================================================
Error
=======================================================
Error:       Bad parent found (parent is not a network): mat/Pig/vrayOutput.init.
   at Deadline.Plugins.PluginWrapper.RenderTasks(String taskId, Int32 startFrame, Int32 endFrame, String& outMessage, AbortLevel& abortLevel)

=======================================================
Type
=======================================================
RenderPluginException

=======================================================
Stack Trace
=======================================================
   at Deadline.Plugins.SandboxedPlugin.d(DeadlineMessage bbf)
   at Deadline.Plugins.SandboxedPlugin.RenderTask(String taskId, Int32 startFrame, Int32 endFrame)
   at Deadline.Slaves.SlaveRenderThread.c(TaskLogWriter aer)

I've included the complete Errorlog and the hip-file in attachment.

The same nodes did manage to render a simple houdini 18 scene with mantra, so It's probably not a deadline or houdini license issue.

Any ideas or suggestions?

Cheers,
Tim

Have you checked this? https://docs.chaosgroup.com/display/...line+and+V-Ray

Hi Andrei,

Thanks for the link, I did as instructed. But strangely enough, the machines that didn't render before, render fine now and vice-versa.

I get a new error on those machines, which would let me to believe there's a double instance of vray now or something. (log in attachment)

Could it be this is because I also installed Vray for Houdini on all the nodes with the installer to the installer's default local location?

In your first post you mentioned 2 of the 4 nodes sucessfully render, without setting up the environment variables (I'm guessing here - I did not see them in the log from your first post). This means somehow V-Ray is being loaded for those 2 nodes.

In your second post you mention the 2 nodes that previously did *not* render are now running fine. This leads me to believe you're loading V-Ray twice on 2 of your 4 render nodes - either through the houdini.env file, environment variables on your machine or there are V-Ray json package files present in the Houdini_Install_folder/packages.

Can you please check if that is the case ?

edit: I did not see this part:

The installer simply adds a json file to the Houdini install folder/packages. Can you please try removing those files and running a Deadline job (with the environment variables set up) again ?

Hope that helps!

Yes! That's it! The other machines weirdly didn't have those although I all installed them the same way. I removed the vray_for_houdini.json and now all machines are rendering as it should. Thanks for your help!
