Hello list,
we do some heavy baking via arnold's render to texture in maya.
Maya had the habit to run out of mem or hang so I'm now batching those bakes by running a new instance of maya each time using subprocess.popen
I've noticed that it's just taking up just one core now though :/ .
Is this a limitation of popen or something else I'm missing here?
Thanks a lot in advance!

It likely won't be caused by Popen. That is just a standard fork and exec for a new process. It will likely be a factor of the command and its options for choosing how to thread.

Thanks!
Mmmh that's sort of worrying. I checked the maya batch options but I didn't see anything there related to threads.Is this something that could be in the actual arnold command? I'll try check with them..

Does anybody have by any chance a version of psutil that works with maya?

It was by the way false alarm .. in my test the baking was going so fast and all I was seeing was (not multithreaded) pre-pro of the scene..
sorry for confusion!
