Vray3 Nightly + Maya2016 + Deadline 6.0 problem

V-Ray V-Ray for Maya V-Ray for Maya :: Issues
1

Hello,

I have a problem and I´m not sure if it´s fully vray related, but at least I get an error message via Deadline quoting that there´s an error in a vray .cpp file.
I´m sending a job from maya2016 (vray3 nightly build from May 12th) to deadline (maybatch)
Tasks start to render, but progress stalls at 96.7% although file is already written out correctly.

In the job report I get the following error message:

0: STDOUT: [2015/May/18|08:02:10] V-Ray: Successfully written image file “S:/Projects/…/filename.exr”
0: STDOUT: [2015/May/18|08:02:10] V-Ray: Total frame time 0h 18m 2.9s (1082.9 s)
0: STDOUT: API error detected in ./VRayNodes/VRayMesh.cpp at line 2804
0: STDOUT: : (kInvalidParameter): value not in valid range

Some other tasks don´t throw an error, but don´t complete either, although file is written.

Log:
0: STDOUT: [2015/May/18|08:03:28] V-Ray: Successfully written image file “S:/Projects…/filename.exr”
0: STDOUT: [2015/May/18|08:03:28] V-Ray: Total frame time 0h 18m 25.5s (1105.5 s)

Any ideas?

Furthermore we have licensing issues with our blades.
We have 40 rendernodes (only 26 blades are active for rendering)
Some frames are set to completed in deadline without generating the file and in the renderlog it says:

0: STDOUT: [2015/May/18|11:46:30] V-Ray: Exporting scene to V-Ray.
0: STDOUT: [2015/May/18|11:46:30] V-Ray: Parsing light links time 0h 0m 0.0s (0.0 s)

0: STDOUT: [2015/May/18|11:46:42] V-Ray error: Could not obtain a license (0).

We didn´t encounter any of those problems with maya2015 and vray3.

“VRayNodes/VRayMesh.cpp at line 2804” means that Maya cannot create a mesh from the given proxy. Without the proxy, I can’t tell you what is wrong.

Looking at the code it seems that a mesh creation function have failed.

Is this error happening only when running through Deadline?
Would it be possible to share the scene with us?

Hi,
thank you for your support!
Actually the API error is not our problem anymore, although we don’t know anything about how it was solved… The license error is solved also.
Our main problem is the task completion with Maya2016 and vray Build 25803 in Deadline 6.0.
The task’s percentage in deadline stops at a random value, mostly at 97 or 100%, sometimes at 50%, although all frames are rendered successfully. some random tasks render fine on the first run, sometimes only on the 5th or 6th try, by random slaves.

We found the following error messages in the reports of the appropriate tasks:

=======================================================
Error
=======================================================
Error in RenderTasks: Monitored managed process “MayaBatch” has exited or been terminated.
bei Deadline.Plugins.ScriptPlugin.RenderTasks(String taskId, Int32 startFrame, Int32 endFrame, String& outMessage, AbortLevel& abortLevel)

<usual render log comes here, nothing curious>

<usually we expect the unloading of Bitmap files , Cleaning up bitmap manager and Render Complete messages here>

<and after some time>

0: WARNING: Monitored managed process MayaBatch is no longer running

Is a relationship to vray possible?

I took a look at the deadline mayabatch.py , where the progress is calculated and the start and endframes are determined, and everything seems to be fine, i think… any changes in vray concerning this?
Btw: Maya2015 works fine with build 25803 and Deadline 6.0

It looks like Maya 2016 crashed at the end of the render. I seem to remember there was a similar issue at some point, will have to check what happened to it.

Best regards,

That would be great! We temporarily switched back to Maya2015, until it’s solved.
