how to limit number of mr threads on one machine?

[Anonymous]

hello,
how do I limit the number of threads/cores that xsi gui uses on my workstation? I have 8 cores but only want mental ray to use 6 so that I can run other apps while test rendering.
is there an environment variable in the setenv.bat?
thanks in advance,
mike

Use the -threads command line argument.

I tried this:

C:\Softimage\XSI_Client_7.0\Application\bin\XSI.bat -threads 1

to start up xsi but it still hogs all cpus when rendering from gui.

Where do I include the "threads" argument? Or, should I be specifying the number of threads in the .ray3hosts file?

Sorry, it's been a long time since I did this. Can't remember. Thanks.

Oops, I meant -thread, not -threads.

For example:

xsibatch -thread 1 -render "%XSI_HOME%\Data\XSI_SAMPLES\Scenes\red_jaiqua.scn"
