Batch Rendering Issues

[RyDarling]

Quick update...

My batch runs for about 30 min and then stops after 30 min or ten frames. I've had it rendering all night.

A few things to note:
- The frames themselves render as expected averaging 3 minutes per frame. Why this is stopping, not sure.
- I've also noticed the task manager shows that my mayabatch is only using like 4,500KB of memory, hours after the last frame rendered.
- This scene rendered out with no issues last week with higher settings.
- Rendering local on my machine.
- I'm going to try creating a fresh scene.... results TBD.

Some scene spec's
- 5.7mil Faces
- Rendering 300 Frames total

Octane Settings:
- Maya Plug-in: 2.24.2 - 7.24
- PMC
- Samples set to: 600
- Verbose mode: ON
- Change names to Unique: ON
- Out of core: off
- Motion blur: off

Where can I find GPU temperature settings?

Where can I find GPU temperature settings?

You have to use a GPU utility, for example GPU Z:
https://www.techpowerup.com/gpuz/

The temperature issue is very common with multi GPU rig cooled by air,
because each cards send hot air on other cards ...
You may have to monitor the GPUs and define a more appropriate curve for the ratio fan speed/temperature,
sometimes under-clocking is needed.

About PMC, maybe someone else could give better hints because I didn't use it often,
but I seem to remember this kernel was more sensitive to GPU heat/instability.

Hey calus,

Thanks for helping me out with this. I took your advice and downloaded what you suggested. I've attached the results. It doesn't seem to be overheating, as far as I can tell.

- This scene rendered out with no issues last week with higher settings.

Oh sorry I missed that, so it does not seem to be GPU failing after all.

A good practice with unstable scene rendering over the night is to separate the batch script by chunk of frames,
for example your .bat could look like this :

Code: Select all

render -r octane -smp 600 -s 1 -e 10 myscene.mb
render -r octane -smp 600 -s 11 -e 20 myscene.mb
render -r octane -smp 600 -s 21 -e 30 myscene.mb
....
render -r octane -smp 600 -s 291 -e 300 myscene.mb

So if one batch line fail the next one is still run.

batch render was always a pain in the a.. in maya.. not only with octane.. and this for years, the bug is in maya self.
vray don t need it & it s a good thing.

it would be great to find another way to render sequences without activating "batch render".

another thing making the rendering stop, i noticed especially with multiple gpu on board,
is that it stops because of a max number of samples exactly the same as the one set in the render globals,
waiting to switch to the next frame.

Hi, i need HELP !!! am having the same problem, am in the middle of a project, never have this problem in the standalone batch render, cant go back to the standalone, the project its ready in Maya and the plugin doesnt render more than 20 frames.

Please, what can i do.

Thanks.
