Iray 幽灵灯光套件 3

幽灵光系列的第三代产品，Iray 幽灵光套件 3 专注于计算成本低廉的体积光照明。 幽灵光是不可见的漫射网格光源，能在无需可见光源的情况下为场景提供照明。本套件中包含的体积光版本，通过带有镂空着色器的网格体积来模拟大气照明效果。最新版的简易幽灵光也包含在内，不再需要设置材质，而是使用空白贴图，从而避免出现瑕疵。套件中还附带了一个大气网格，可为场景营造出柔和的雾气效果。 通过 Iray 幽灵光套件 3，用户可获得五种不同的体积光照明风格，以及两种简易幽灵光照明风格。此外，每种照明风格都提供了强度、颜色和实用选项等多种配置选项。 每盏灯还配有一个视口显示图标，可帮助用户放置和调整灯光方向，但在渲染时该图标会自动隐藏

The third iteration of the Ghost Light series, Iray Ghost Light Kit 3 focuses on computationally cheap, volumetric lighting. Ghost lights are invisible, diffuse mesh lights that light your scene without a visible light source. The volumetric version of these lights included with this set mimic atmospheric lighting effects by using mesh volumes with cutout shaders. The latest iteration of simple ghost lights are also included, which no longer requires setup materials and utilizes blank maps which avoid artifacts. An atmospheric grid is also included with the set to cast a subtle haze across the scene. With Iray Ghost Light Kit 3 you get a total of five different volumetric light styles, along with 2 simple Ghost Light styles plus many intensity, color and utility options for each. Each light also has a viewport display icon that will help you place and orient your light, but which will hide at render-time.
