Grey squares when using Vrayspawner as a Service

V-Ray for 3ds Max V-Ray for 3ds Max :: Issues

Hi,

I’m having problems with DR. If I run Vrayspawner as a Service on the slave machines, their buckets render everything grey. I tried turning off the firewall but that didn’t help. However, if I run Vrayspawner from the exe file, everything is fine. Please check the attached render.

This is most likely because V-Ray Spawner service uses Local System Account which doesn’t have rights to access the project assets.
Make sure that the spawner service uses a windows account which has the necessary rights to access the shared files:

More information on that matter could be found here:

Thanks for the reply. I will try this out and write back with the results.

Svetlozar.. is that windows 95 you are using? :wink:

This is Windows 7 with customized theme :slight_smile:

I now had some free time to try this. Unfortunately I didn’t manage to make it work. I typed “Administrator” in the 1st field and then a password. Then I restarted the service and an error message appeared:
“Windows could not start the VraySpawner 2016 service on Local Computer. Error 1069: The service did not start due to a logon failure.”

What exactly should I type in these 3 fields?

With the computers at my office when I run DR as a service I type in my own login name and pass, so:

This Account: Your User Name
Password: Your Pass for your account
Confirm Password: Type the password again to make sure they match

Thanks a lot for your help, Syclone. However, I don’t think I have a password for my account. When I turn on my PC it starts right off, without log-in screen asking for password. Or maybe I have one but I don’t know what it is? How can I find out if I have a password and what it is?

Do you have password set for your user account (the user must be with admin rights)

This pass should be used for V-Ray spawner Logon settings.

Thanks, Tashko. I don’t think I have a password since Windows has never asked me for one when turning on my PC. Here’s how my User Accounts menu looks like:

Can you let me know what should I do? Thanks a lot for your help. I hope we can get this working. :slight_smile:

In this case you can set password for this user (it must have the necessary rights to access the folders where the texture files are stored) and follow the instructions from our docs :
section > Mapped Drives and UNC Paths for Texture Maps and Other Rendering Assets
Chaos Docs

If you still have any problems to set the render node to work properly with DR, please send us an email to support at chaosgroup.com

Sorry for bringing up this old thread but I think I found why I couldn’t set up VraySpawner as a service! After spending long hours searching on the internet, I found this and this page. From what I read there, it seems that only accounts that are part of a domain network structure can be granted remote access to other files through services (such as the VraySpawner service). Am I right? And since the PCs I was trying to run the VraySpawner service on are on a workgroup instead of domain, VraySpawner service is impossible to be set up. Can someone confirm? Or is there a trick to make workgroup PCs run the service nevertheless? Should I change the networking structure from workgroup to domain and are there benefits in doing so?

Hi,

There is no difference if you are part of domain or Workgroup. You need to set-up V-Ray spawner service to use as Log in account a user that has read/write access of the shared resources over the network. For further information how to setup the Log in account of a user, please refer to our help here:
