Maya hard crash when Max render threads set higher than the workstation has?

[jasonhuang1115]

Hi,

I have experienced this several times where I saved a scene with Max render threads set to 32 on box A (that has 40 HT threads, Xeon CPUs), and later on opened the scene on box B that only has 8 HT threads (i7 CPU). Hit render and then Maya crashed. As soon as I set the Max render threads to "0" or a value lower than 8, the scene renders just fine.

Can Vray automatically set the thread value back to ex. "0" in this situation to avoid a Maya crash?

Thanks,
Jason

It's a known issue which unfortunately we didn't manage to fix for the last update.

Yes, this can be a possible fix for this issue Will keep you posted for any news.

Thanks Tashko. Yes, I think it wouldn't be too bad to reset that value to "0" automatically in this situation. At least it's renderable and when user "realize" less responsive UI, they can always check the thread number setting again.

Actually that's exactly what we did, but we accidentally broke it a few days ago. It should be fixed in tomorrow's nightly build. Thanks for reporting!
