The Texmap plugin is designed to render materials with a complex index of refraction (IOR). While standard materials (e.g., V-Ray, Corona Renderer) can calculate the Fresnel effect for dielectric materials like plastic using the IOR (n), metals require a more intricate Fresnel reflective curve. This curve is also influenced by an additional parameter called the extinction coefficient (k), defined as: \u03b7<\/em>=n<\/em>+ik<\/em> Here, n<\/em> and k<\/em> determine two key characteristics of the Fresnel curve for a material: the reflectivity at normal incidence and the rate at which it fades to white at grazing angles.<\/p>\n\n\n\n

The Texmap plugin can be used as a reflection color map in a material with the Fresnel option turned off, as the plugin performs its own Fresnel calculations.<\/p>\n\n\n\n

Parameters<\/h2>\n\n\n\n
    \n
  • n<\/strong>: The IOR values for the Red\/Green\/Blue wavelengths (0.650, 0.510, and 0.475 \u00b5m).<\/li>\n\n\n\n
  • k<\/strong>: The extinction coefficient values for the Red\/Green\/Blue wavelengths.<\/li>\n<\/ul>\n\n\n\n

    Presets<\/h2>\n\n\n\n

    The plugin includes several presets for a quick start. To input custom n<\/em> and k<\/em> values, select the “Custom” preset.<\/p>\n\n\n\n

    Color Adjustments<\/h2>\n\n\n\n

    For different colors (e.g., for various alloys), use the Color Adjustment parameters to modify Gamma, Hue, and Saturation values. This ensures the Fresnel curve remains correct while allowing color changes.<\/p>\n\n\n\n

      \n
    • Gamma<\/strong>: Specifies the gamma correction value.<\/li>\n\n\n\n
    • Hue Shift<\/strong>: Adjusts colors using a standard Hue spectrum. Range: -180 to 180.<\/li>\n\n\n\n
    • Saturation<\/strong>: Controls the intensity or purity of colors. Lowering the value desaturates the color, while raising it intensifies the color. Range: -100 to 100.<\/li>\n<\/ul>\n\n\n\n

      Obtaining Values<\/h2>\n\n\n\n

      You can find measured n<\/em> and k<\/em> values for many metals (e.g., Copper, Gold, Iron) on Refractive Index Database.<\/p>\n\n\n\n

      Installation<\/h2>\n\n\n\n
        \n
      1. Copy the file \u201cComplexFresnel_xxxx.dlt\u201d to the MAXROOT\\plugins directory (delete any older version of the file if present).<\/li>\n\n\n\n
      2. Use the appropriate file for your 3ds Max version:\n
          \n
        • ComplexFresnel_2013.dlt<\/strong>: Compatible with 3ds Max 2013\/2014<\/li>\n\n\n\n
        • ComplexFresnel_2015.dlt<\/strong>: Compatible with 3ds Max 2015\/2016<\/li>\n\n\n\n
        • ComplexFresnel_2017.dlt<\/strong>: Compatible with 3ds Max 2017<\/li>\n\n\n\n
        • ComplexFresnel_2018.dlt<\/strong>: Compatible with 3ds Max 2018<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
