Messages

Verbosity Level: Controls the verbosity level for messages related to mental ray rendering. Messages equal to or below the selected verbosity are displayed. Messages are displayed in the mental ray log file.

Parallelism

Auto Render Threads: If Auto Render Threads 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.
Render Threads: 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.
Auto Tiling: Turn on this option to automatically determine the optimal tile size at render time.
Task Size: Pixel width and height of render tiles.

Network

Used for network rendering only.

Select one of these options to determine whether the local machine renders the scene, or whether the slaves render the scene.

Render on the local machine: Select this option so that the local machine participates in rendering the scene.
Render on network machines: 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.

TipTo render on all available machines, select both the Render on the local machine and Render on network machines options.

IPR Tuning

Update upon visibility changed (slower translation): Select this option so that IPR updates when there is a visibility change in your scene, such as the hiding and unhiding of geometry.
