Can you tell me which version of V-Ray for Maya? Also, did you install V-Ray for Maya by running the installer, or you are running from a remote location? Looks like it didn't find some of the V-Ray shaders...

Best regards,
Vlado

We had to switch back to Maya 2011 completely because 2012 was just too unstable and always crashed on us. Hopefully Maya 2013 will be better...

[setes]

we use the version vray_adv_21001_maya2012_x64_20494, and was installed by the installer, the dongle is on the same computer where the problem occurs, it happens very often when it rebuilds preview dell'hypershader

[vlado]

Ok then; can you try one of the newer stable builds? Let me know if you don't know how to access these. Also, can you send me the .dmp file from the Maya crash report to vlado@chaosgroup.com ?

Best regards,
Vlado

looks like some issue with rendering thumbnails. As Vlado pointed out, maybe a new build would solve it, also turning off thumbnail update might be a workaround.

I'll like to know how to download and use newer builds..

Thanks

Hello,
You can log in with your account at http://www.chaosgroup.com/en/2/downloads.html, and download the latest V-Ray version according the OS and software you use.
Note that the new installer will remove the old V-Ray version, and probably after installation you may have to start the License Server again.

[obrad1972]

I've download 2.20.01 from 3. feb. 2012.. Is that latest version or there are newer builds (like hot fixes etc) ?

Thank you

[tashko.zashev]

Exactly, this is the latest stable V-Ray build for Maya.
Install it and tell us if the problem persist!
