vray 3.6 using standalone and missing DLL's

[delineator]

Pretty straight forward, but right now this is a killer for us because its holding up our Deadline workflow. Confirmed the same error pops up whether rendering via Deadline OR whether running the standalone vray.exe from the command line:

 error: Error loading plugin library "C:\Program Files\Chaos Group\V-Ray\V-Ray for SketchUp\extension\vrayappsdk\bin\plugins\vray_BRDFSimbiont.dll": LoadLibrary failed (126): The specified module could not be found.

There is a DLL by that name at that location, so not sure what's up.

Additionally, even though the vrscene was saved with hybrid enabled, I'm not sure it saved anywhere in the vrscene file and is not using my GPU when rendered via command line - will vrscene hybrid rendering be a feature in the future?

used -rtengine=5 via command line/standalone and its using cpu and gpu, so that answers that.

You can safely disregard this error message. The missing plugin is not supported and its absence does not affect your render output in any way.

Regarding the Hybrid render mode, there are some specifics when setting up CUDA devices.
If you use the dropdown list of devices from the Asset Editor's Engine setting, you will set them up only for the current session in SketchUp. This selection will be lost upon exiting SketchUp and will not be preserved in the project.
To set up default CUDA device selection used any time you open V-Ray for SketchUp, simply go to the SketchUp menu Extensions > V-Ray > Tools > GPU Device Selection. Alternatively, you can find the tool at the following location:
C:\Program Files\Chaos Group\V-Ray\V-Ray for SketchUp\extension\vrayappsdk\bin\ocldeviceselect. exe

To mark your CPU as CUDA device, select the "C++/CPU" entry.
This tool directly affects the environment variable which V-Ray takes into account.

After setting up your preferred device combination, open V-Ray Standalone and start a CUDA render (using "-rtengine=5"). Look at the progress messages - there will be info printed for each CUDA device used. For example:

Querying for CUDA devices...
Device 0 is C++/CPU.
Device GeForce GTX 750 Ti has compute capability 5.0
(...)
 Using 7 threads for C++/CPU, 4 threads per GPU device
(...)
Number of CUDA devices: 2

There will also be statistics for each device usage near the end of the progress log.

Kind regards,
Peter

Thanks for the variable tip - i'll see about implementing that with Deadline and see what I can get working. However, this error message CAN'T be disregarded because it stops the rendering when done via deadline. As mentioned, the command line rendering continues, however, we render via deadline and this faulty error message is halting our entire workflow

Is there a way to implement a quick hotfix or a file I can edit to ignore/remove this error? I can't deploy 3.6 to our office until this issue is fixed.

For now, disabling "Strict error checking" should resolve your issue. Our dev team will look into removing the Simbiont plugin checkup for v3.60.02. Thank you for letting us know!

Kind regards,

I think thats a maya thing only via deadline:

Unless I'm missing something and there is a variable for vray standalone that I could implement?

Hmm, no, you are correct. There is no "Strict error checking" for V-Ray in Deadline. You can contact Deadline support about it.

As a temporary workaround for your issue, backup and delete vray_BRDFSimbiont.dll which is located in C:\Program Files\Chaos Group\V-Ray\V-Ray for SketchUp\extension\vrayappsdk\bin\plugins .

Kind regards,
