The tools on the Diagnostics rollout can help you understand why the mental
ray renderer is behaving in a certain way. The Sampling Rate tool, in particular,
can help explain the renderer's performance.
Each of these tools generates a rendering that is not a photorealistic view, but
a schematic representation of the functionality you have chosen to analyze.
Interface
Enable When on, the renderer renders the graphic representation for the
tool you have chosen.
Sampling Rate When chosen, renders an image that shows where samples
were collected during rendering; see
Sampling (mental ray Renderer) on page
7914 . This can help you adjust the contrast and other sampling parameters.
Coordinate Space Renders an image that shows the coordinate space of
objects, the world, or camera.
Object Shows local coordinates (UVW). Each object has its own coordinate
space.
World Shows world coordinates (XYZ). The same coordinate system
applies to all objects.
Camera Shows camera coordinates, which appear as a rectangular grid
superimposed on the view.
Size Sets the size of the grid. Default=1.0.
