'Writing Output' to Network is extremely slow

[deneb26]

Hello

maybe some of you also encountered this behaviour while rendering through backburner.
I have a QNAP NAS (newest firmware) with a few network folders and everytime a rendering finishes and outputs the render elements to the NAS, it takes horribly long.
The writing speed is around 100-200kB/s.
What's so annoying is the fact, that this behaviour began 2 weeks ago.
I have a second QNAP NAS (also newest firmware) and there it works like it should. I checked differencies in network folders (r/w rights, contingents, ect.) and there are none.
Copying files/folders from one NAS to the other, or from folder to folder on the same NAS, works like a charm.
Btw. it doesn't matter if I render with vray or corona render. So I assume it has something to do with the NAS or backburner...probably should going to their forums...

cheers
Ale

Are you using the "Separate render channels" option in the V-Ray VFB? If yes, then the saving is done by 3ds Max itself and there isn't much that we can do about it. You could try using the "V-Ray raw image file" option to write a single multi-channel OpenEXR file instead.

Best regards,
Vlado

Hi Vlado

thank you for the fast response!
Yes, I'm rendering to separate render channels through vray VFB. Never used the vray prorietary file-format, but I'll give it a try.
Strange, that it never was a problem before...oh well!

Best regards
Ale

Update: Writing to a Vray Raw-Image EXR did the trick. Thanks again for the tip; will save me a lot of time
