次表面工作坊 —— Iray 渲染器的 SSS 着色器教程

提到次表面散射，大多数人首先想到的都是皮肤，以及利用该技术让角色看起来更逼真的重要性。但在现实世界中，各种材质都会存在次表面散射现象，而要想让这些表面看起来真实自然，次表面散射同样至关重要。 Subsurface Workshop 旨在将这些逼真的效果引入您的素材库。其中包含 150 种全面预设，适用于布料、蜡、塑料、液体等材质。该套装中的所有预设均设计为注入器，可与现有纹理信息配合使用，因此能轻松应用于您现有的所有内容。 另外，还附带了 150 种仅含次表面散射效果的预设，让您能够为已有的满意材质添加次表面散射效果，在不改变反光度等参数的情况下，为材质增添新的特效

When most people think of subsurface scattering the first thing that comes to mind is skin and the importance of using it to make characters look realistic. In the real world subsurface scattering is in all sorts of materials though, and it's often just as important when making those surfaces look real. Subsurface Workshop intends to bring these realistic effects to your library. Inside you'll find a huge library of 150 full presets for cloth, wax, plastics, liquids and more. All presets in this set are designed as injectors meant to work with existing texture information so they're easy to use on all your existing content. The additional 150 included SSS Only presets allow you to add subsurface scattering effects to materials you're already happy with, adding the new features without changing things like speculiarity.
