Sampling (mental ray Renderer)
Sampling is an antialiasing technique. It provides a "best guess" color for each rendered pixel. The mental ray renderer first samples the scene color at locations within the pixel or along the pixel's edge, then uses a filter to combine the samples into a single pixel color.
(In 3ds max, this technique is called "supersampling." Because the mental ray renderer performs sampling on a scene basis, in the Material Editor, you don't need to turn on supersampling for materials rendered using mental ray.)
Note: The Renderer panel appears only when the mental ray renderer is the currently active renderer.
To use low sampling for previews:
Leave the Minimum and Maximum values at their default settings of 1/4 and 4, or reduce them to 1/16 and 1/4.
Tip: Do not assign Minimum and Maximum the same value.
To use high sampling for final renderings:
Increase the Minimum and Maximum values to 4 and 8, or to higher values.
Tip: Do not assign Minimum and Maximum the same value.
