Vray-RT Failing

[corestudio]

Hi. I can't get the Vray RT (or distributed rendering) to work. I get a message about the network server not starting up. See below. Odd thing is that I think it was working earlier. This is on multiple machines. Thanks.

Is it possible that you have another Vray started in the background listening to the same port ( 48 ) ?

[corestudio]

possible since we have both 2015 and 2016. How would I check?

[savage309]

You can check the built in Activity Monitor in OS X. In the CPU tab just sort by name and search for vray. If it is there, stop it using the X button in the top left. If you don't find it there you might run the terminal command "ps aux | grep vray" - if there is vray running, you will see the path to the executable listed (should be something like /Applications/Autodesk/etc). Optionally you can try "sudo pkill -9 vray" - if there is vray running, this will kill it.

Thanks for the help. So it seems there is only one process running

gfx01:~ gfx01$ ps aux | grep vray
root 152 0.0 0.1 2596372 40016 ?? S 1:50PM 0:00.37 /Applications/Autodesk/maya2016/vray/bin/vray.bin -server -portNumber=20207 -display=0
gfx01 494 0.0 0.0 2432772 672 s000 S+ 1:54PM 0:00.00 grep vray
gfx01:~ gfx01$

I've tried killing it and even re-booting. Here is quick output from the Script Editor when I tried a quick Vray RT:

setToolTo CreatePolyCylinderCtx;
polyCylinder -ch on -o on -r 3.676594 -h 5.199489 -sc 1 -cuv 3 ;
// pCylinder1 polyCylinder1 //
select -af polyCylinder1 ;

// Warning: line 1: Render host gfx01.corestudio.x (127.0.0.1:20207) is not responding //

that last warning is the issue, correct? I've tried manually starting bin/vrayslave but that doesn't work and anyway I still get:

[2015/May/8|13:58:08] Failed to start network server: Failed to open listening port (4

any ideas?

[savage309]

If you have killed it and it starts up again, it means that most likely you have started in some kind of service-like mode (this is strange however, pkill command should've worked). I can't help with that, since I am not familiar with it, but some of the support guys will help you.

[vlado]

Yeah, that means there's already a copy of the render server running on that port. Perhaps it would help to unregister the render server from the Mac OS X services and let V-Ray for Maya run it manually.

Best regards,
Vlado

Thanks Vlado. I ended up running unregisterVRaySlaveDaemon for all copies of vray (could maybe an option for new installs?) and then re-ran registerVRaySlaveDaemon for 2016. Seems to be working. We're actually using it in production. (Rolling the dice! But seems good so far)
