Overview


Both the V-Ray render server and distributed rendering spawner service can be set up to run automatically when Windows boots.

 

The V-Ray Standalone version included in the 3ds Max installer is intended for DR use when V-Ray GPU is set to ActiveShade or Production mode. It is not a replacement for the 3ds Max render slave, which is intended for use with the V-Ray renderer.

Register V-Ray DR spawner as service


You can register the V-Ray spawner service so that it runs automatically on Windows boot from the Windows Start > Programs > V-Ray 4.0 for 3ds Max... > Distributed rendering > Register V-Ray spawner service.


In order for the spawner to work properly, you need to run at least one regular network render job with BackBurner on the render slave.

 

When registering the V-Ray DR spawner for 3ds Max 2015 as a service it will always ask for a Username and Password. This means that additional commands need to be added if you want to do that on multiple machines through an unattended install. There are two different approaches:

 Add "-quiet" to the command line - this will install the service from the Local Service Account and won't ask for username/password. Then you will need to set a real user for the VraySpawner2015 service to use it

 

Example: "C:\Program Files\Autodesk\3ds Max 2016\vrayspawner2016.exe" -service -quiet

 

Add params "-username=..." and "-password=..." (without the quotes) to the command line - this will try to use the supplied username/pass to register the service.

 

Note

- if the user name or password contains spaces it must be in quotes. For example: -username="John Smith"
- If the user is part of a domain - it must contain the domain too: -username="DomName\John Smith".
- If the log file for the spawner (located in %temp%) contains messages like:


*** ALERT! Couldn't create service: The account name is invalid or does not exist, or the password is invalid for the account name specified.

and there is no domain you could try adding ".\" to the user name: -username=".\John Smith"

Register V-Ray GPU render server as service


You can register the V-Ray GPU render server as a Windows service so that it runs automatically on Windows boot from the Windows Start > Programs > V-Ray for 3ds Max > Register V-Ray GPU render server as a service.


Normally Windows services do not have access to the graphics cards. It is possible to use V-Ray GPU as a Windows service only with a compute card like an NVIDIA Tesla card with appropriate compute drivers.


Select devices for V-Ray GPU


V-Ray GPU can run on one or more OpenCL/CUDA enabled graphics cards. To specify which cards are to be used, go to Windows Start > Programs > V-Ray for 3ds Max > Select rendering devices for V-Ray GPU 4.0 for 3ds Max and pick
