玻璃透明效果优化

优化前:

    fn setParam = (
      local mt = makeMt mtName
      mt.texmap_bump.normal_map.fileName = Normal
      local c = (1-粗糙度)*255
      mt.Reflection = (color c c c)
      c= 250-不透明度*100
      mt.Refraction = (color c c c)
      mt.reflection_metalness = 金属度/10.0
      mt.texmap_bump.normal_map.coords.U_Tiling = 法线密度
      mt.texmap_bump.normal_map.coords.V_Tiling = 法线密度
      mt.texmap_bump.normal_map_multiplier = 法线强度
      mt.refraction_ior = 折射率
      mt.Diffuse = 颜色
    )

优化后:

    fn setParam = (
      local mt = makeMt mtName
      mt.Diffuse = 颜色
      mt.texmap_bump.normal_map.HDRIMapName = Normal
      mt.texmap_reflection.output.RGB_Level = (1.0-粗糙度)
      mt.texmap_refraction.output.RGB_Level = (1.0-不透明度)+ 0.15
      mt.reflection_metalness = 金属度/10.0
      mt.texmap_bump.normal_map.coords.U_Tiling = 法线密度
      mt.texmap_bump.normal_map.coords.V_Tiling = 法线密度
      mt.texmap_bump.normal_map_multiplier = 法线强度
    )

优化前:

    fn setParam = (
        local mt = makeMt mtName
     --mt.texmap_bump.normal_map.fileName = Normal
      mt.Diffuse =颜色
      mt.Reflection = (color ((1-粗糙度)*255) ((1-粗糙度)*255) ((1-粗糙度)*255))
      mt.Refraction = (color ((1-不透明度)*50+200) ((1-不透明度)*50+200) ((1-不透明度)*50+200))
      mt.reflection_metalness = 金属度/10
      mt.texmap_bump.normal_map_multiplier=法线强度
      local nc = mt.texmap_bump.normal_map.coords
             nc.U_Tiling = 法线密度
             nc.V_Tiling = 法线密度
    )
