Network rendering via Backburner not saving render elements in .vrimg file?

[Richard7666]

All I get is the beauty and alpha elements in my .vrimg
When I render locally, I get all my elements in the file

I am rendering using the 'progressive' sampler, if that's relevant.

Any ideas?
Thanks

Does this happen if you render with BB locally on the machine? Does it happen with a specific scene only? Also can you send us BB log?

Aha! Was nothing to do with backburner as the issue was local as well.

Seems I need to enable 'V-ray raw image file' in the Frame Buffer section of the V-ray tab, and pick a save location for my .vrimg file in there.
I had been setting the save location for my .vrimg in the Common tab instead, which was only saving the beauty and alpha.

That's correct, the output from Common tab only writes RGB and Alpha channels.
In order to export render elements it's necessary to output the image from V-Ray Frame Buffer rollout.
