Windows Security Updates = Broken DR

[Bruce Hart]

If this helps anybody - We've found that a recent security update has broken distributed rendering on our network. We have Windows 10 workstations and Win 7 render farm machines running Max 2017 and Vray 3.04.02
The specific updates are KB3177725 (Windows 7) and KB3172729 (Windows 10). As a side note - the same patches stopped Revit workstations being able to print.

Cheers

Thanks for sharing this info. Hope the next Windows update will fix the damages caused by this one.

Hi Tashko,

i have DR Problem too. After install Vray 3.40.2, DR will not work anymore. i am using win 10-64bit version1607 on the client and Win10-64bit version 1511 on the Renderserver.
Could be this the problem? But Before updating to 3.40.2 DR worked well, even with that different win10 version.
here is the Log from the Render Server:
is there any Solution now or Workaround? Thank you!

best regards

Hi,

I'm not sure what is the issue here and it would be a good idea to test with one very basic scene first to see if the same issue will occur. Then we will see how to proceed further.

[ptjie]

Hi Tashko,

i am using already very basic scene. my problem is: the render server can in fact load the scene, and it starts frame 0, but i dont see any bucket of this server in the vray frame buffer. i see only the main clients buckets. sorry if i dont describe my problem well.

best regards

i did update both all machines to windows 10 build 1607. 64 bit, vray newest 3.40.03 and 3dsmax 2016 sp3. firewall is already set to open vrayspawner. vrayspawner run as service with account permission. but DR still wont work

what does it mean? [2016/Aug/30|20:17:55] [DR] frame data is NULL, aborting

could anyone help please? thank you in advance

Hi,

That message means that the render slave is not able to load or receive the required parameters for the current rendering process. Unfortunately it is very difficult to say what exactly is the problem here without logging to this machine. So what I can recommend in this situations is to contact us via our support mail (support@chaosgroup.com) in order to arrange a remote session. You can also add a link to this forum thread.

[tashko.zashev]

If this helps anybody - We've found that a recent security update has broken distributed rendering on our network. We have Windows 10 workstations and Win 7 render farm machines running Max 2017 and Vray 3.04.02

Cheers

By the way, I just did quick test to see if there are any problems with the windows 10 update KB3172729, but DR seems to work fine here.

Edit: tested on Max 2016, I will try that on 2017 as well.

[ptjie]

Hi Tashko,

thank you for your offering. i sent an email to support. i hope they conntact me for remote session

Thank you. We just received your mail and will reply shortly.

Hi Tashko
Thanks - that's interesting. Perhaps in my case the problem is to do with that security patch on a Win 10 machine trying to send DR to Win 7 machines. Maybe if we had Win 10 all round things would be OK. All I know is, once we deleted the Win 10 security patch - we could distribute render once again.

Sorry I forgot to update this thread since the communication went via email.
Actually we managed to replicate the DR problem here on one workstations but we are not able to figure out what is going on yet. Machines with similar software (Windows anniversary update, which most probably includes KB3172729 patch) and hardware configurations works fine in DR renderings with build 3.4 but that one has this problem. We can't confirm at this point that there is any connection to the Windows updates.

[infunctievan]

Hi, is there any update concering this problem ?
We are also have this issue here with DR...
Restarting the spawner service on the machine fixes it but it's very annoying.

Thanks !
