Let’s start where we left off last time<\/p>\n

\u25cfRefraction<\/i><\/b><\/span><\/p>\n

\u30fbIndex of Refraction
\n<\/b>The amount that a ray of light bends when entering a material\u3002
\nA value of 1 equals air, a value of 1.33 water.
\n\"05_mia_material_x_11_IOR\"<\/a>\u30fbColor
\n<\/b>Refraction color.
\n\"05_mia_material_x_12_Refr_color\"<\/a>\u30fbTransparency
\n\"05_mia_material_x_13_Transparency\"<\/a><\/b>\u30fbGlossiness
\n<\/b>Determines the smoothness of the surface for refraction.
\nIf this value is lowerd, rendering time will increase.
\nIf a rendering takes time too much, below-mentioned Interpolate Refraction is set up.
\n\"05_mia_material_x_14_Refr_Gloss\"<\/a><\/p>\n

\n

\u30fbGlossy Samples
\n<\/b>S<\/span>pecifies the number of times the light ray is sampled: a low value is grainy; a high value is smooth.<\/p>\n

\u25cfAdvanced Refraction<\/i><\/span><\/b><\/p>\n

\u30fbUse Max Distance
\n\"05_mia_material_x_15_Refr_MaxDist\"<\/a><\/b><\/p>\n

\u30fbUse Color At Max Distacne<\/b>
\nWhen this parameter is ON, It is\u00a0attenuated<\/span>\u00a0to the color specified by “Color At Max Distance”.<\/p>\n<\/div>\n

When this parameter is OFF, the color is black<\/div>\n
<\/div>\n

\u30fbColor At Max Distance<\/b><\/p>\n

\"mia_material_x_passes<\/a><\/div>\n
<\/div>\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>The threshold at which refractions are not traced anymore<\/p>\n

\u30fbThin Walled\/Solid<\/b>
\n\"05_mia_material_x_17_solid\"<\/a><\/p>\n

\u30fbRefractive Caustic\/<\/b>Transparent Shadow<\/b>
\nWhen we use caustic, \u00a0Refractive Caustic parameter set ON.
\nHowever, it is necessary to set up that\u00a0\u00a0caustic\u00a0may become effective by the light and rendering setup.
\n\"05_mia_material_x_18_caistoc\"<\/a><\/p>\n

\u30fbBackface Culling
\n<\/b>Makes surfaces invisible to the camera when seen from the reverse side<\/p>\n

\u30fbPropagate Alpha
\n<\/b>If this is off, transparent objects have an opaque alpha channel.
