Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

cores and threads
In Maya MentalRay I am using a MacPro 2 x 2.26 Quad-Core (a dual quad core), with 16MB RAM, running OS10.6.8. My image is a single frame 2D for print. The image size is 2592 x 750 ( I have rendered much larger) and the scene is fairly intense with lots of image maps, etc. As I said I have rendered much larger and equally complex but this render is cutting out at 30% or so.
I switched to Batch Render and set my threads to 16 and it worked.
So my first question is, is 16 the right number of threads?
My second question is why the render is quitting in the first place?
No other programs running.
Thanks for any responses.

It's odd since 2010 most render issues are with batch render not render view. If I had to make a stab in the dark, and that is all it is, I would say it's a render cache issue. You might want to bring up the performance monitor (if you are running windows) and look at the memory use as it renders.
As for threads in both batch and render view options there is a section parallelism and in that section you can uncheck automatic and try typing in the number of threads manually (In your case 16). Keep in mind, unless they have changed it, if you do not have the stand alone mental ray renderer you are limited to 8 threads. It used to say that in the output window when the mr plugin loaded but now I do not see it, but I think there is still a limit unless you purchase the stand alone MR renderer.
Also, under memory you can uncheck auto memory limit and you can type in your own value. Their is a calculate button but that sometimes produces a value that is too large and so you also crash.
Finally, if you have mental-ray satellite running make sure it's configured properly or turn off render to network machines.
Best of luck,

As for the render window, it is still not playing nice (stopping at about 10%). In the little rendering progress window (just below the MEL scripting line) something like "MentalRay memory low. Aborting", appeared for just a few seconds and then the rendering stopped—but NO error message in the log. I decided to go for the settings listed above erring on the side of caution I went with 7000GB and hit the "redo previous render" button. No go.
Now I move over to the logs at /username/Library/Logs/Maya/mayaRender.log and there's nothing there. The last piece of log info is from yesterday. Now I'm really stumped.

To your second question, I don't know, what is the verbosity level in your batch options message settings?

Thanks for all the feedback. Sometimes it can be difficult to get replies back to Mac questions.
