USE MENTAL RAY'S IMAGE SAMPLING WISELY

Scene sampling for antialiasing can be a complicated task for any renderer, even a sophisticated engine such as mental ray. If you're just doing preview renderings (to test your lighting, for example), you can speed up your workflow considerably by mental ray sampling only what you really need.

Figure 6.31Figure 6.31

If you're simply working on your overall scene composition and lighting, leaving the mental ray Samples per Pixel Minimum/Maximum values at their defaults costs you unnecessary time. The default values (Minimum 1/4, Maximum 4) mean that mental ray will take 4 samples per 1 pixel in areas with many details, or 1 sample per 4 pixels in areas with fewer details.

If you set both Minimum and Maximum Samples per Pixel to 1/64, mental ray is forced to only take 1 sample for each "bucket" of 64 pixels. This creates a coarse rendering, but it renders at incredible speed and might be just what you need to get your overall look correct before you commit to production-level sampling settings. Just save this setup as Render Preset (on the Rendering > Renderer tab, at the bottom of the dialog box). Call it "Rough Preview" and keep it handy for future use.
