场景的设置是一个很重要的步骤，如果不了解如何进行构思是很难得到好的结果的。在教学的第一部分你将对这个项目有所了解，明白场景的制作方式，从而能够顺利的学习下面的主题。
跟往常一样Houdini给到了我们很多实现同一个任务的方法，今天我们将进入SSS的世界，然后学习它提供给我们的各种不同的方法，通过一些直观的例子，你将会学习到如何使用这个功能，还有让它正常工作需要做些什么。
1 表面散射。
2 照明与材质。
3 细节渲染设置。
The setup of the scene is a very important step, getting a nice result would be difficult without a good understanding of how it was conceived. In the first parts of the lesson you will be introduced to the project and to the way the scene is built to give clarity to move through the topics smoothly.
Subsurface Scattering
As usual, Houdini offers many ways to accomplish a task and the same goes for Subsurface Scattering. We'll dive into the world of SSS and the different methods it offers. Using strait forward examples, you will understand how to use this feature and what is needed for it to work correctly.
Lights And Materials
Light affect directly the SSS results. We'll talk about how to create and assign the non SSS materials and most importantly, how to create the SSS material for our juice. Understanding how to start a material, if it is a modified built in Houdini material or if you'll be starting from scratch is always something to think about when searching the right look for your render. Mastering attributes on the points of an object and use them inside your shading network will become clear to you.
Render Refinements
To finish off this image, you still need to create the material for the straw, which will also need SSS, so you will apply one more time what you've learned so far to create that material and get your Juicy result!
