1.29 Diagnostic modes2.1

mental ray supports a number of diagnostic modes that help visualizing and optimizing the rendering process. They modify the output image to include grid lines or dot patterns that indicate coordinate spaces or sampling or photon densities. These graphs allow simple detection of insufficient or excessive sampling densities, and help to tune parameters such as numbers of photons or sampling and contrast limits.

Diagnostic modes are enabled with the -diagnostic option on the command line, or the diagnostic statement in the  options block in the scene description file.
