3ds Max 2015에서 Mental ray 업데이트면서
iray를 지원하는 문자열 옵션이 올라왔습니다.
"iray bloom filtering" <bool>
activates or deactivates a crude bloom filter (default off)
"iray bloom filtering radius" <float>
radius of filter in percent of image resolution (default 0.01)
"iray bloom filtering brightness scale" <float>
scales the intensity of the bloom effect (default 1.0)
"iray bloom filtering threshold" <float>
values beyond the threshold will be considered “bright” and thus used for the bloom effect (default 0.9)
"iray degrain filtering" <int>
select degrain filter (0 = None, 1..5: different variants) (default 0)
"iray degrain filtering radius" <int>
radius of filter in pixels (default 3)
"iray degrain filtering blur difference" <float>
only needed for modes 4 and 5 (default 0.05)
"environment dome mode" <string>
set the environment dome mode, which can be “infinite” (standard
infinite environment lookup), “sphere” (sphere shaped dome),
"hemisphere" (sphere shaped dome where the lower hemisphere is projected on the plane dividing upper and lower hemisphere), or "ground"
(infinite environment, but with a textured ground as in hemisphere
mode), default “infinite”
"environment dome position" <float float float>
set the center of the environment dome (default 0 0 0)
"environment dome radius" <float>
set the radius of the environment dome sphere (default 100)
"environment dome rotation axis" <float float float>
set the axis to rotate the dome (default 0 1 0)
"environment dome rotation angle" <float>
set the angle (0..1) for the rotation around the rotation axis (default 0)
"environment dome ground" <bool>
enable or disable the shadow catcher plane (default off)
"environment dome ground position" <float float float>
set position of the ground plane (default 0 0 0
)
"environment dome ground shadow intensity" <float>
controls the intensity of the shadow on the ground plane, values above
1.0 are allowed but can lead to strange behavior (default 1)
"environment dome ground texturescale" <float>
adapt the scaling of the texturing of the ground plane texture
"environment dome ground glossiness" <float>
set glossiness of ground plane
"environment dome ground reflectivity" <float float float>
set reflectivity of ground plane
"iray interactive mode" <bool>
enables interactive scheduling (otherwise batch scheduling is used)
"iray baking texture width" <int>
"iray baking texture height" <int>
controls maximum texture baking size (for unknown texture shader nodes)
"environment lighting resolution" <int>
allows reducing preprocessing time at the cost of lower resolution
"environment lighting blur" <bool>
allows to additionally blur the environment slightly (low resolution
environments will tend to look blocky/pixelated otherwise) (default off)
"iray firefly filter" <bool>
enables/disables the firefly filter (default on)
"iray nominal luminance" <float>
The nominal luminance is a hint to iray on what is considered a
“reasonable’’ luminance level when viewing the scene. This luminance
level is used internally to tune the firefly filter and error estimate.
When the nominal luminance value is set to 0, iray will estimate the
nominal luminance value from the tonemapper settings. If a user
application applies its own tonemapping without using the built-in
tonemappers, it is strongly advised to provide a nominal luminance.
Recommendations: For visualization, a reasonable nominal luminance would be the luminance value of a white color that maps to half the maximum brightness of the intended display device. For quantitative
architectural daylight simulations (e.g. irradiance buffer), a reasonable nominal luminance could be the luminance of white paper under average day light. (default 0.0)
