Vray Beta 2 build crashing consistently on Distributed rendering on farm

[vlado]

Well, it seems to crash after the frames are rendered and saved, so you should be able to render the thing even with the crashing, no?

I can but it stalls out and tries to rerender the frame after reporting that the crash was an error which causes the frame to immediately start over until a non crashed version of the frame goes through.
The other issue is that sometimes the frame doesn't complete entirely on the vrimg write and one or two of the channels (usually the multimattes) come out partially corrupted.

Just tried another setup..stripping all of the Shave and a Haircut data out of the scene and limiting all the textures...I was hoping that maybe the error was on the shave side of things causing the crash...looks like that's not the case.

The only other thing I think that may be crashing the render is the light cache.
I'm going to send off a job where it is disabled, see what happens.

Does the fact that each of the render nodes are dual 12 core hyperthreaded xeons have any potential issue (the idea being that the light cache threads may screw up past 16?)

For continuity sake I've attached the error from the shave free attempt

I THINK that its been figured out.
Metzger and I went through things piece by piece and I managed to get a consistent render out of the box.
It looks like a bug with the scene referencing.

By creating the scene from scratch and redoing all referencing things seemed to render.

I won't really know until tomorrow when the farm parses the scene but here's hoping that maybe it will get through.

[BadRobotProductions]

Well..looks like the crashing is still occurring.

[vlado]

Yep, I don't think there is much to be done on your end to fix it. I think I should have a fix for this a bit later today.

Best regards,
Vlado

[BadRobotProductions]

Thanks..Here's hoping for soon!

[beatmanb]

Is there a fix planned soon? When I DR Render with my farm, Maya is hanging at the end...VRay Frame Buffer hanging...need to restart Maya...
Works without the VFB, but I want to use it for the render elements...

all the best,
beatmanb

[vlado]

Is this on Windows with Maya 2012?

Best regards,

[beatmanb]

Yes, it is Windows with Maya 2012...
Is that a known bug that will be fixed soon?

All the best,
beatmanb

[vlado]

It's fixed in the nightly builds since some time now. If you want to get these, please email us to vraymaya@chaosgroup.com
