次表面散射(Sub-Surface-Scattering)简称3S，用来描述光线穿过透明/半透明表面时发生散射的照明现象，是指光从表面进入物体经过内部散射，然后又通过物体表面的其他顶点出射的光线传递过程。
次表面散射仍然在左耳上清晰可见。
The Sub Surface Scattering is still very visible on the left ear.
工业光魔的渲染使用先进的次表面散射技术模仿光线穿过这些材料的效果。
ILM's renders used cutting edge subsurface scattering techniques to emulate the effect of light passing through such materials.
这就是最终的模型。我给脸部和手部创建了次表面散射。现在是时候绑骨骼和摆姿势了。
And there he is. The final model. Created Subsurface Scattering for the face and hands. Now its time to rig and pose the character.
