mental ray Connection Rollout 1461
Inter face
Use Global S ettings—When on, the material uses
the supersampling opt ions set in the Default
Scanline Renderer rollout (page 3–38).Default=on.
Enable Loca l Supersampling—When on, applies
supersampling to the material. Default=off
Sampler drop-down list—Lets you choose which
supersampling method to apply. The list is not
active unless Use Global Se ttings is turned off.
Default=Max 2.5 Star.
Super sampl e Ma ps—When on, the maps applied
to the material are supersampled as well. When
off, the supersampler uses pixel averages for maps.
This switch is active only when Use Global Settings
is turned off. Default=on.
Quality—Adjusts the quality of supersampling by
controlling the number of samples used for each
pixel. At the minimum value, 0.0, four samples are
taken per pixel. At the maximum value, 1.0, ab out
40 samples are ta ken per pixel (the value varies
depending on which shader is active). Range=0.0
to 1.0. Default=0.5.
This spinner is unavailable for the Max 2.5 Star
method.
Adaptive—VisibleonlyfortheAdaptiveHalton
and Adaptive Uniform methods. When on, these
methods take fewer samples than the Quality
specifies unless samples show a change in color
greater t han the Threshold value. In that case,
they take all the samples specified by the Qualit y.
Turning on Adaptive On can reduce the amount of
time required to supersample. Default=on.
Threshold—Controls the Adaptive methods.
VisibleonlyfortheAdaptiveHaltonandAdaptive
Uniform methods. A change in color greater than
the Threshold value causes t he adaptive methods
to take the f ull number of samples specified by the
Quality.Ifthecolordoesnotchangeasmuch,the
adaptive method takes fewer samples and does not
require as much processing time. Can range from
0.0 to 1.0. Sett ing Threshold to 0.0 has the same
effect a s turning off Adaptive On . Default=0.1.

material other than a Multi/Sub-Object o r a mental ray
material. > mental ray Connection rollout
The mental ray Connection rollout is available for
all t ypes of materials except t he Multi/Sub-Object
material and the mental ray m aterials themselves
(for which it would be redundant). With this
rollout you can add mental ray shading to
conventional 3ds Max materials. These effects are
visibleonlywhenyouusethemental ray renderer
(page 3–78).
Impor tant: The mental ray Connection rollout does
not appear unless you have enabled the mental ray
extensions by using the mental ray Preferences panel
(page 3–837). In addition, you can’t assign shaders to the
options in this rollout unless the mental ray renderer is
the currently active renderer.
