Recently I had to reinstall my system and currently Vray RT works only in CPU mode. When I launch it in GPU mode the active shade window freezes on ‘waiting for image data’ and a windows window pops up with an information that vray stand alone has crashed, trying to find a solution … (something alon…

Ok, thanks I’ll give a try ! cheers

I updated one of my workstations to vray 2.2 today. Looks like I have the same problem with vray-RT hanging on “Building OpenCL trace program …”. It’s been running for 50 minutes now and still no sign of life… The workstation is a dual xeon with 24GB RAM and a quadro 4000. Any recommendations for a…

am having the same problem. Updated from 2 to 2.2 and lost ability to RT on GPU (except in my case it’s a 5700 ATI instead of an nvidia). Tried rolling back vray to 2 again and it would crash each time I ran it. Reinstalled drivers (11.11) and vray 2.2 and still no go as far as running VrayRT for …

[image] Post your Simple Render here. Reinstalled drivers (11.11) 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 fro…

YES now I have my log back. I updated my ATI drivers to latest (11.12) and the GPU Render still is coming out black (except lights) while CPU RT works fine. Here is the log; hope somewhere in there is an answer. Thanks again [VrayRT GPU render.png]

[image] Liquid: a few questions about flow and shape 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…

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 wo…

[image] Multiscatter or Forest Pro? 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. It doesn’t matter that the variable is not defined. It…

[image] Vray 2.1 Seems to be saving the proxy within the max file 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. Isn’t the ‘ocldeviceselect utility’ a 3DSMax tool? I am using Vray for Maya. S…
