C4DtoA - Team Render Server fails to Render AOVs - C4D R21.115 - C4DtoA 2.6.1.5

Hi,


I'm having an issue with AOV passes failing to render on a 28 node Team Render Server controlled Farm.

The project is submitted with display driver present and multiple active AOVs in the Arnold Renderer settings (ref image attached).

When the project is run locally the AOVs along with the Beauty pass as epexted.


But when run on the Team Render Server farm - only produces the main beauty and alpha are returned. It appears to ignore all AOV requests.


Is this a know issue with Team Render? Is there a possible fix/workaround?


We've only recently updated our Render Farm to support Arnold - but this AOV problem has affected all Arnold projects submitted to it.


Our local machines and the render nodes are running:


C4D R21.115


C4DtoA 2.6.1.5 [a79361bf]


Arnold core 5.4.0.2


Any help with the above would be greatly appreciated!

Thanks for your time!

I could reproduce both issues:

  • AOVs are not saved when running team render job via the web interface.
  • Failed to send data errors in the client log (seems to be unrelated to the first issue)

Working on the fix.

This is now fixed in C4DtoA 3.0.3.1

You might need to add an exr driver for outputting as right now you only have a display driver... see screenshots below, that's my typical output settings and it works over team render

I always bypass C4D's output settings and set the Format to "Arnold drivers only" then set the driver's file path to the path I set in C4D's Mutli-pass settings in the Save section

Thanks so much for the response Eden!

I'll give that a try - much appreciated!

Saving from C4D's output settings should work as well. I made a couple of tests and I don't see any problems. Not sure what's going on.

You're trying to render single frame, right? Does rendering animation any diffrerent?

Can you check the Arnold log? Set log level to Debug in Render Settings > Diagnostics and it should print out the log in the Team Render Client console.

Hi Peter - thanks for the response!

I've run a simple animation test with AOVs saving out through C4D's output settings (not using an Arnold Output Driver) and the AOVs are writing correctly from the farm.

Running that same job as a Single Frame (with all other settings the same) produces the issue of no AOVs being written (just a Beauty file and an alpha file).

I tested Eden's suggestion of an Arnold Output driver (both Tiff and EXR tested) on the original job - but I'm afraid it failed to write the AOVs.

Afraid I'm struggling to get hold of the C4DtoA log - as once submitted to Team Render Server all I am returned is Team Render's log *attached* which looks like it doesn't contain any useful C4DtoA info.

I tried specifying a file path for the Debug log to be written to - but looks like this hasn't worked, might be a write issue our IT side - currently investigating.

Have also tried running the project with the Multipass set to a layered EXR - but this still fails to produce the AOVs while running on the farm.
