Failed to read library config file

[Anonymous]

It seems like Bifrost cannot load the library config file off a unc network drive on windows.  

  Warning: Bifrost: Failed to read library config file \\Bluearc\..\windows\plugin_config.json  

  Error: Error: Failed to locate Json doc 'bifrost::\\Bluearc\...\windows\plugin_config.json'

Similarly, if I modify my MAYA_MODULE_PATH to use posix slashes I get the same result.

  Warning: Bifrost: Failed to read library config file //Bluearc/../windows/plugin_config.json

  Error: Error: Failed to locate Json doc 'bifrost:://Bluearc/.../windows/plugin_config.json'

Our equivalent linux network folder for Bifrost works fine on linux.

Hi there,

Since you're on windows, the network drive should be mapped as a drive letter using the 'Map Network Drive' feature. Then when you specify the network path via env var, you can use the drive-letter-path, i.e. P:\..\windows\etc

Cheers,

Ryan

Hi Ryan,  Thanks for the suggestion.  Unfortunately mapping network drives is not an option at our studio.  We have dozens of other plugins/modules/renderers(including arnold) that work just fine on UNC paths.  This seems like it would be a very minor patch for the bifrost devs to make it more consistent with industry norms.

\\Bluearc\..\windows

is this the actual path you enter?  what is that ".." doing there instead of the share name?  

[jonah.friedman · Accepted solution]

Ryan has confirmed that this indeed doesn't work in the current releases. I've opened BIFROST-3311 for the issue. I hope to get you an update about this soon. 

Thanks Paul.

The ".." is not in the actual path.  I am suppressing our long/client-sensitive path.

Thanks Jonah!  🙂

Hi, I want to share a similar problem :

// Loading Bifrost version 2.0.2.0 //
// Warning: Bifrost: Failed to read library config file c:\app\autodesk\bifrost\2.0.2.0_maya2018\bifrost\resources\plugin_config.json. //
// Error: Error: Failed to locate Json doc 'bifrost:c:\app\autodesk\bifrost\2.0.2.0_maya2018\bifrost\resources\plugin_config.json'. // 

Here, 

c:\app\autodesk\bifrost

is the network mount point.

No problem on Linux.

Any workaround to share?

Thanks in advance!

[jonah.friedman]

Hi Dorian Fevrier,

This is actively being worked on and should be fixed in an update soon. 

[Narann]

Thanks Jonah! We will wait for it!

Have a good day!

Hi Jonah,

I'm waiting for the fix as well....

Thanks!

I hate to revisit such an old thread, but I'm having a similar issue.  We use Modules in Linux and Maya is installed in a non-standard location.  We have a variety of env variables set to make everything work...  except these:

Warning: Bifrost: Failed to read library config file /usr/autodesk/bifrost/maya2024/2.7.1.0/bifrost/resources/plugin_config.json.
Warning: Bifrost: Failed to read library config file /usr/autodesk/bifrost/maya2024/2.7.1.0/bifrost/packs/packs_plugin_config.json.

Nothing in Bifrost will render and I can't figure out where to override these paths.  The plugin loads fine, Looks great in the viewport even, just won't show in the render.

Here is a single frame of the burning barrel sample rendered at the CLI.

For the record, setting:

Doesn't work. Already tried that.

[syracoj]

what's "the CLI"?

for this
Warning: Bifrost: Failed to read library config file /usr/autodesk/bifrost/maya2024/2.7.1.0/bifrost/resources/plugin_config.json.

you have checked that the plugin_config.json file is in that directory?

what happens if you set 

export MAYA_MODULE_PATH=/usr/autodesk/bifrost/maya2024/2.7.1.0
if that doesn't work you can 
unset MAYA_MODULE_PATH

This assumes Bifrost is installed in /usr/autodesk/ correct?

arnold is installed in usr as well?

you are trying the burning barrel example correct? If so, can you try and get just a create_mesh_sphere plugged into the output node to render with a directional light? In other words, take the burning barrel example out and see if something simpler will render.

[macintosh]

CLI is Command Line Interface.  Our renderfarm is headless.

Nothing is installed in /usr.   They insist that they run as modules, and I lode the module and it (normally) works.  In this instance though, the Bifrost objects are not rendering.

I confirmed that the error only means that it can't find Bifrost at it's nortmal location. The Env variables are working and Bifriost is loading afterward.  I can enable -X X11 forwarding  and see the fire in the viewport. Bifrost *is* there.  It just doesn't render.

So we're going to reinstall Arnold in hopes that it solves the issue.   This has worked before, so I'm unsure what's not working in this instance.

[syracoj]

Please let us know what happens.
