Flamenco render job submission fails

Submitting certain .blend files to the Flamenco manager results in an error, apparently occurring when copying associated assets from the .blend file to the Flamenco render job folder. Trying multiple files, I found that I can generate this error with an audio file in the video sequencer or when I have an external Alembic file referenced absolutely in a Mesh Sequence Cache modifier, even if that file is in an accessible location.

Sample file with WAV sound in the video sequencer and an Alembic file reference.

Which version of the Blender Cloud add-on was used?

Latest version as of yesterday (1.13.4) but with the wheel file you had sent me (attached here)

Please give us files we can use to reproduce the issue. The blend file you uploaded packs just fine, albeit with warnings about missing files.

It would also help to know the layout of your files. What directory is set as the project directory? You're using drive R:, is that a network drive (if so, which protocol?) or a local disk?

Adding a sound file to the sequencer in an empty .blend file was enough to reproduce the error for me, but I am attaching this actual file. This file has the proprietary elements removed, including the WAV file in the sequencer. To get this to submit to Flamenco without error, I have to delete the WAV audio and both the Alembic fluid surface and the Ocean modifier fluid surface.

I have been able to successfully submit to Flamenco a version of the file that has the object with an Ocean modifier, but only when the Cache path for that modifier was empty.

UPDATE: It looks like just changing Cache path helped submit this, as I wasn't able to submit today with an empty value but then changing it to "//" a relative reference to the current folder, it submitted.

It would also help to know the layout of your files. What directory is set as the project directory? You're using drive R:, is that a network drive (if so, which protocol?) or a local disk?

As an addition to these not-yet-answered questions: what have you set as job storage and job output directories? With the Flamenco-Error.blend file you're using the D: drive, what kind of drive is that?

D:/ is a local physical data drive on my main Win 10 workstation.
R:/ is the Flamenco project.
R:/ is a network mapped folder location to D:/Flamenco, so in the case of submitting the job, R:/ points to the same hard drive. R:/ was created using Windows "Map network drive", which I don't believe allows you to specify a protocol.
All Flamenco workers have an R:/ mapped back to my workstation, which is also running Flamenco manager.
Inside R:/ are three folders:

  • JobStorage - Flamenco writes its files to these folders
  • SourceFiles - I save a copy of .blend files to be rendered here, as I have to be in the Flamenco project (R:) to submit.
  • TempImages - Folder for the standard JPEG images being written. This is essentially for display on the Flamenco manager screen last rendered image. I purge this folder a lot, as I use the compositing node editor to generate multi-EXR files.
