The 3.1 update looks great except for an issue I’m having with vRay RT. A normal bucket or progressive render works just fine, its only when I try to do realtime rendering where I’m having problems.
I’ve captured a quick video:
It seems to do a quick first pass then stop. I was sure that I was missing a check box or something but I have everything on default settings and you can see that the test scene I create in the video is not complex a tall.
Have I missed something really obvious? could it be a firewall blocking RT server perhaps?
Thanks

Can you show the log from the vray.exe RT process?
Sure can you tell me where that would be saved on my computer?
I’ve noticed that I don’t get the command prompt window anymore when I do an RT render session so I’ve been using the Maya output window instead. Is this normal behavior?
Sorry probably should have just googled it in the first place.

You can post the log from the output window as a start.
It will tell us if the vray.exe has crashed.
The log can also be found in the %TEMP% folder. It should be called vray4maya_log.txt.
Hm, interesting. Can you check if there is vray.exe running in the task manager?
Can’t see vray.exe in the processes tab.
What happens if you start “vray.exe -server” manually from the start menu or in a command line prompt and then you try to use RT?
Not sure if I’m doing something wrong but I’m not having any success unfortunately.
Shall I try reinstalling? I have RT working in 2015 also the RT window inside the Hypershade seems to work just fine.

You must first stop the VRayMayaSpawner201x service from TaskManager → Services. Then run vray.exe -server
Okay I’ll give that a try. I will get back to you when I can get IT to enable admin control on my workstation.
I have found a spawner service running for Maya2015. It would make sense that this could be cancelling out my 2016 when I try to rt render.
IT have been learning how to setup Deadline so maybe they have made it so 2015 spawner is always running which is now conflicting with 2016.
Will let you know what happens when I can stop the service.
Yep, I guess this is the problem. You are starting the RT of Maya 2015 and rendering with 2016. The V-Ray versions don’t match and you get a crash after RT update. You must start the 2016 spawner, or use different port for each Maya version.
Stopping the background service fixed the issue. Thankyou very much for your help Ivaylo.
