VRay standalone has stopped working

V-Ray V-Ray for Maya Issues
1

Since the day I bought , Vray cannot render in RT…sometimes it starts but a few more tweaks on the scene
then …no more RT…“Vray standalone has stopped working”…scene has a cube and light.
I got a brand new Boxx maximus…running Maya 2012.
Should I reinstall Vray? feels like a bug.
Any help?

What version of V-Ray are you using?
Cpu or Gpu version?

3

the latest one 64 bit 2.20.01

I’m rendering in RT open Cl…tesla card and quadro 6000
Please I need a solution for this to use on Robocop film production…

Hi,

So you’re running RT GPU?
Have you tried a nightly build?
What drivers are you using?

Thanks Teodor..I have the latest Nvidia drivers…but I don’t know what a nightly build is…please clue me in…

Also, which OS? Does it matter what is the scene?

Best regards,

Windows 7 professional, the scene is quite simple…it may start running RT but eventually will fail…

9

Do you get an image before that? Can you show me the console output of the RT render server?

Best regards,

Vray is working fine, I did some great set renders yesterday, but could not adjust my shaders and lighting with RT…had to Frame buffer do adjust the scene…I would like to send one of my simple test scenes I’ve been using to
detect the problems but
it fails to upload the file from the office here…might try another way soon…thank you.

Ok, will wait for more info then.

Best regards,

The Rt renders a black scene, that’s when I know Vray standalone crashes…although VRAY still working fine with frame buffer…just the RT crashed in reality

I’ll have to find the console output info later Vlado…

13

Vlado I sent you a simple zipped scene thru your email…

14

Yes, thanks a lot - like I said it will be fixed.

Best regards,

Hi Vlado, I’m still waiting for the nightly builds page..The one sent to me yesterday didn’t work …I sent my username and password to Chaos but no new link has been sent yet…I understand you guys are busy but I’m still stuck here.

I downloaded the nightly builds Vlado and RT is working…Thanks…although the default 512 resolution for textures is not acceptable for my needs and I raise to 2048…that crashes the RT every time.
I guess this Rt is only going to work as a preview render…will have to render always in frame buffer unfortunately.

Well, the next update will have the CUDA engine available, which handles larger textures somewhat better. Also for the moment, all textures are upload to the GPU as full floating-point, which is quite wasteful. Again for the next update, they are uploaded by default as 8-bit (although you can change that), so that 4 times less video RAM is used.

Best regards,
Vlado
