MENTAL RAY IS ON THE COUCH!

Do you get tired of tweaking your mental ray settings over and over again but not getting exactly the results you're looking for? You can help diagnose your problems by using the aptly named Diagnostics rollout. Just pick mental ray as your production renderer (see the previous tip); then, in the Render menu, click the Processing tab and under Diagnostics: Visual, check the Enable box.

Turning on Diagnostics: Visual gives you an invaluable tool to optimize and tweak your render. You can choose to diagnose your pixel sampling rate (for antialiasing problems), coordinate space, photon emission, or the BSP (Binary Space Partitioning) Tree—all the areas in which your rendering times can be short and sweet or be stretched out until the heat death of the universe.

As an example, to adjust your photon settings, open your scene, make sure you have mental ray as your assigned renderer, and then go to Rendering > Render > Indirect Illumination and make sure you have your photon generators set. (Check the Global Illumination Enable box.) Go to the Processing tab, and under the Diagnostics section, enable Visual and set it to Photon. Now when you render, you'll see a "false color" representation of your scene, showing areas with dense photons as red, and areas that are lacking photons as blue. You can then use this visual guide to tweak your photon count and photon radius until your diagnostic render shows a smoother range of color, with red in the most important areas of your scene. When you're ready to do your final render, turn off Diagnostics: Visual, and you're all set!
