I checked and summarized “mia_material”<\/p>\n

Although there was a blank part of the knowledge which has not yet been buried, I wrote about each parameter as a memorandum.<\/p>\n

Please let me know if there are any mistakes.<\/p>\n

I used Maya2013 to my research.There are three types of “mia_material”.
\nThey are expansion to the order of [mia_material]\u2192[mia_material_x]\u2192[mia_material_x_passes]I think it is good that we always use [mia_amterial_x_pass]\n

\"[mia_material_x_passes<\/a><\/p>\n

\u30fbMultiple Output<\/i><\/span><\/b>
\nWhen you output multiple passes(for example Reflection, Refraction pass), we enable this parameter.
\nI think it is good that this parameter is always enabled.
\n\u25cfDiffuse<\/i><\/span><\/b>
\n\u30fbColor<\/b><\/b>Diffuse Color.?We connect a color texture to this parameter.<\/p>\n

\u30fbWeight
\n<\/b>Diffuse strength. ?if this parameter is?\uff10, it’s meens no Diffuse.
\n\"05_mia_material_x_02_dissuse_weight\"<\/a><\/p>\n

\u30fbRoughness
\n<\/b>roughness of the diffuse surface
\n\u25cfReflection<\/i><\/b><\/span>
\n\u30fbColor
\n<\/b>Reflection Color. If this Color set black, It meens no reflection.
\n\"05_mia_material_x_03_reflective\"<\/a><\/p>\n

\u30fbReflectivity
\n<\/b>The amount that the surface reflects.
\nThe value which multiplied the below-mentioned BRDF becomes final reflectance.
\nSo\u3000It is necessary to consider reflection by BRDF and a set.
\n\"05_mia_material_x_04_reflectivity\"<\/a><\/p>\n

\u30fbGlossiness
\n<\/b>
\nThis parameter defines how sharp or blurry the refraction is
\n\"05_mia_material_x_05_refl_Glossiness\"<\/a><\/p>\n

\u30fbGlossy Samples
\n<\/b>If Glossiness Parameter is not set to 1.0, we can change this parameter.
\nLower values render faster, but create a grainier result. A value of 32 is adequate for most cases.<\/p>\n

\u30fbHighlights Only
\n<\/b>Displays only highlighted. It meens No Reflection.
\n\"05_mia_material_x_06_HighlitsOnly\"<\/a><\/p>\n

\u30fbMetal Material
\n<\/b>When this parameter is on, the Dissuse Color parameter defines the Reflection color parameter.
\n\"05_mia_material_x_06_Metal\"<\/a><\/p>\n

\u25cfAdvanced Reflection<\/i><\/span><\/b>
\n\u30fbUse Max Distance
\n<\/b>When this prameter is on, We can use refl_falloff_dist parameter.<\/p>\n

\u30fbMax Distance
\n<\/b>Limits the refractions to within a certain distance
\n\"05_mia_material_x_07_MaxDistance\"<\/a><\/p>\n

\u30fbFade To End Color
\n<\/b>Refractions fade out to this color.
\n\"05_mia_material_x_08_EndColor\"<\/a><\/p>\n

\u30fbMax Trace Depth
\n<\/b>This parameter overrides rendersettings Max Trace Dept(?). When this parameter is set to 0, rendersettings Max Trace Depth Parameter is used.<\/p>\n

\u30fbCutoff Threshold
\n<\/b>Applies an opacity map to completely remove parts of objects.<\/p>\n

\u30fbNo Highlights For Visible Area Lights
\n<\/b>When “Mentalray Area Light” Visible Parameter is ON, this parameter is effective.
\nWhen This parameter is ON, It prevents being doubled by the highlight of a mentalray area light.
\nI think iti is good, always this parameter is ON.
\n\"05_mia_material_x_10_NoHighlight\"<\/a>
\n\u30fbSkip Reflection On Inside<\/b>
\nIgnores faint reflections that are on the inside of transparent objects, which saves rendering time.
\nContinue to net time…<\/p>\n
