These seem rather old; have you tried newer drivers?
It would also seem that I have lost the ability to see the log (that would pop up when rendering).Do you see vray.exe in the Task Manager (make sure that “Show processes from all users” is enabled)? If yes, you probably registered the V-Ray RT render server to run as a Windows service. In that case you can try unregistering it (from the Start menu), killing vray.exe and trying a new RT render.

Hi! Same problem here: Win 7 XP64, Dual Xeon, Quadro 4000, latest NVidia-drivers. After waiting 1 hour for building the OpenCL trace program, VRay-standalone crashes. Also when rendering with CPUs…
If it crashes on CPU, then it’s a different issue. Does it happen on any scene?

RT working in CPU not GPU (Maya)
Hi All,
I am having the same issue with RT rendering on CPU and not GPU. The issue started after installing Vray for Maya 2.20.01 (just released). Basically the initial OpenCl build hangs - I have tried letting it run for 10 minutes, an hour, two hours…nothing worked. I am not sure if this is related, but I keep getting ‘warning: Scene is empty’ messages popping up on the Maya command line. The test scene isn’t empty, it consists of a very simple sphere, plane, vrayMtl, vrayDomeLight. Initially I had the same issue with the previous stable build of Vray and, as another person posted, it magically fixed itself after a few attempts (although I may have added an environment variable too, can’t remember exactly). No such luck here though - I tried for hours yesterday, very annoying.
One thing I noticed in the log is an undocumented environment variable that Vray says it can’t find called VRAY_OPENCL_PLATFORMS_x64. Can someone shed some light on this? Perhaps setting it would help.
Also, I looked at the environment variables Vray setup on installation (I used the .exe, not the zip file) and under System Variables there is one called VRAY_PATH with no value associated. What should the path be? Is this by design? Not sure if the installer messed up.
See below for the log from the Vray/Maya command window and my system specs.

It doesn’t matter that the variable is not defined. It is set by the ocldeviceselect utility and is useful if you have more than one GPU installed.
Also, I looked at the environment variables Vray setup on installation (I used the .exe, not the zip file) and under System Variables there is one called VRAY_PATH with no value associated. What should the path be? Is this by design? Not sure if the installer messed up.V-Ray does not use this variable (it was added by the previous installers for information purposes).
Which is the driver version by the way (as reported by the NVidia Control panel, should be something like 276.xx or similar, not the cryptic 8.17.12.7642)?
In any case, do you get any processor usage while the OpenCL program is being built? If yes, then it is not hung, just taking its (very long) time. On the not-so-bright side, GeForce cards tend to work much better for this.
Best regards,
Vlado
Isn’t the ‘ocldeviceselect utility’ a 3DSMax tool? I am using Vray for Maya. Setting it couldn’t hurt right? One less error. Would I set it to the device number? (i.e. 0 for my one GPU)
Noted - will delete that entry.
Sorry about that - it is the Quadro 276.42 driver. I have had no issues with it at all and it has been available on the Nvidia site for about 6 weeks.
According to the Windows Task Manager\Processes\vray.exe holds at a steady 4% in the CPU column while trying to build.
I looked in the Maya Script Editor and saw this:
// Warning: [SettingsJPEG] No image writer specified. //
// Warning: [SettingsPNG] No image writer specified. //
// Warning: [SettingsEXR] No image writer specified. //
// Warning: [SettingsTGA] No image writer specified. //
// Warning: [SettingsTIFF] No image writer specified. //
// Warning: [SettingsSGI] No image writer specified. //
// Warning: No scene found; cannot create OpenCL renderer plugin. //
// Warning: Scene is empty. //
What is this ‘Scene not found’ issue? It seems to me that I could let this try to build forever but if it can’t find a scene, whats the use?
Also, when I close the Vray command window while it is trying to build the Maya Script Editor returns: // Warning: Render host bresboxx (127.0.0.1) is not responding //
Could this be some sort of communication error? Just trying to think of everything.
That isn’t what I want to hear… And frankly, at this point, shouldn’t be the case.
Thanks,
-Nick Breslow
No, it’s not just a number unfortunately; it would be best to leave this alone - things will work fine (assuming they work out eventually :))
Sorry about that - it is the Quadro 276.42 driver. I have had no issues with it at all and it has been available on the Nvidia site for about 6 weeks.Ok then; there is a developer driver for CUDA 4.1 that might work better, but I don’t know if it supports Tesla/Quadro cards, but I’m not sure it will work, I have to try it out.
According to the Windows Task Manager\Processes\vray.exe holds at a steady 4% in the CPU column while trying to build.Ok then; here it takes about 1 hour 10 minutes of that to build the code for a Tesla 2075 card.
What is this ‘Scene not found’ issue? It seems to me that I could let this try to build forever but if it can’t find a scene, whats the use?For this particular issue, it doesn’t matter what it says in Maya; the OpenCL runs in the V-Ray Standalone, not in the V-Ray for Maya plugin.
Could this be some sort of communication error?Nope. It’s just slow. Waiting it out is the only way to get it working.

Vlado
Hi Vlado,
First, thanks for the quick and informative replies - very much appreciated.
Ok then; here it takes about 1 hour 10 minutes of that to build the code for a Tesla 2075 card.
Jeez - I literally let it run for 2 hours last night and no luck. Does it confirm the build in the Vray command window when complete? I seem to remember it confirming the build and giving the time. It used to just ‘work’. I guess I am just a bit dumbfounded as to why my machine with the specs listed above (it rips through everything else) could be taking so long.
The compiled binary winds up somewhere, right? I think a Win user temp folder if memory serves. Can I watch there to confirm it is actually building? If so, what folder? And if I do get this going, how can I make sure it doesn’t get deleted - seems like the Temp folder isn’t the best place for this.
Thanks,
-Nick Breslow
Yes, it will be obvious when it is done. > It used to just ‘work’.Our OpenCL code gets more complicated, so I guess the OpenCL compiler needs more time (why it needs it only on Quadro/Tesla cards though is beyond me).> I guess I am just a bit dumbfounded as to why my machine with the specs listed above (it rips through everything else) could be taking so long.I’d love to know that too, but only the guys at nVidia know the answer

And if I do get this going, how can I make sure it doesn’t get deleted - seems like the Temp folder isn’t the best place for this.It is in the temp folder and in fact I just realised that we do have a Quadro 5000 card here and I can just give you the compiled code to dump into your temp folder - I will try to do that tomorrow.

Vlado,

You are a real gentleman and all around great guy - Thanks so much. I will give it another shot also..do you know the path (i.e. is it in a sub-folder or just %USERPROFILE%\AppData\Local\Temp) it ultimately winds up in?
-Nick Breslow
Just type %temp% in Windows explorer and you’ll get there.
Best regards,
Vlado
Got it - will look for your Quadro compile tomorrow and attempt my own. Thanks again,
-Nick Breslow
Vlado!
It finally worked - took 3 hours 20 minutes. I guess I wasn’t patient enough. Thanks for all your help - I guess persistence pays off. Very much appreciated,
-Nick Breslow
Yes, happens on any scene.
Best regards, Tobi
sorry, im having the same problem with radeon hd 7970 on mac pro, cpu renders fine, gpu blue screen, did anyone try this card yet? sorry my native language is spanish.
I just got a 7970 a few days ago, but I haven’t plugged it into my workstation yet; I hope to get there tomorrow and see how it goes.
Best regards,
Vlado
