VRay Next Update 2 - DR Crashing on Windows 10 Master

[vasquez888]

Hi,

I'm experiencing an issue with DR when one of the newer machines on Windows 10 picks up the job as a master. It will get to the denoising stage and then it'll crash. If an older machine on Windows 7 picks up the job as master, it will denoise and output the image without issue. For a bit of context, the DR job is sent to the network so one of the render nodes can pick up the job and act as master.

What I found when comparing the vraylog on both the machines was that the newer machine couldn't load in the plugins.

I've tried copying the plugins folder from the Windows 7 machine to the Windows 10 machine to no avail. The dlls listed under the Windows 10 machines are not present on both machines.

Any help would be much appreciated

Cheers

Hello,

It seems like the V-Ray installation on the Windows 10 machines somehow got messed up.
The Win10 one has this line

2019/Jul/22|09:21:25] Loading plugins from "./vray_*.dll"

and the Win7 one has the correct path:

[2019/Jul/19|17:43:21] Loading plugins from "C:\Program Files\Chaos Group\V-Ray\3dsmax 2018 for x64/bin/plugins/vray_*.dll"

Can you try reinstalling V-Ray on the Win 10 machine and see if it fixes the problem ?

Best regards,
Yavor

Thanks Yavor.

We'll have a look at reinstalling and will advise on the result.

Hi Yavor,

It doesn't look like it fixed the problem. We have downloaded the latest version of VRay (vray_adv_42001_max2018_x64) and have reinstalled it.

The error still occurs below

I've tried uninstalling VRay manually and reinstalling it but the error still remains.

[yavor.rubenov]

Hm - in that case:

1. It would probably be easiest if you can you drop an email to our support (support at chaosgroup.com) - they can arrange a remote session and see why the installer fails to set the proper paths.
2. Alternatively you can try the following:
   1. Uninstall V-Ray again
   2. After the uninstall - check for any remaining environment variables related to V-Ray for 3ds Max 2018 like this:
      then and then delete those : also if you see any other variable related to V-Ray for 3ds Max 2018 in both fields - delete it. The installer should set them properly the next time.
   3. Install again (using the installer you already downloaded). During the installation check this screen:
      The path for "V-Ray for 3ds Max additional files" should be like the one in the screenshot. If it is not - you can change it by clicking the Customize button.

Hope that helps and sorry for the inconvenience.

Thanks for the reply, Yavor. We'll give your suggestion a go and if the problem persists, I'll contact support as suggested.

Appreciate your help.
