                              are displayed. Messages are displayed in the mental ray log file.

                            If  is enabled, Maya automatically calculates the number of threads that should be used to best take advantage of the CPUs (or
                              cores) on your workstation. This option is on by default.

                            Specifies the number of rendering threads to be used by mental ray for Maya for rendering. Use a thread for each CPU you utilize
                              on the local host.

                              Select this option so that the networked machine(s) participate in rendering the scene. This is useful in reducing the workload
                                 on the master machine while Maya is also running.
                               Tip 
                                    To render on all available machines, select both the  and  options.
