现在是时候开始烘培了，有趣的是并没有许多法线贴图烘培插件开发出来。
Then it's time to start baking, interestingly there aren't that many normal map baking plugins out there.
现在你应该理解了法线贴图是如何起作用的，不过，法线贴图是如何制作的？
So now you get the idea of what normal maps do... but how are they made?
这是惟一一种能被用与可边形物体的法线贴图类型，例如被蒙皮和绑定骨骼的角色。
This is the only type of normal mapping that you can use on deformable objects such as skinned or boned characters.
例如，如果我们有一个光源从正右方照射来，我们可以只适用法线贴图中的红色分量。
For example, if we have a light source directly to the right, we can just use the red channel.
下图演示了将法线贴图附加在低分模型上，这里你可以看见各个分量分别为表面添加了那些附加的信息。
Here the normal map is applied to the low-detail model, and you can see how each channel encodes the surface information along each axis.
使用导入设置，它也可以在游戏中为不同类型的应用而被转换成一个立方体贴图或法线贴图。
Using the Import Settings, it can also be converted to a Cubemap or Normalmap for different types of applications in the game.

考虑到生成法线贴图的目的，你甚至无需将几个构成组件合并焊接起来，就像它们本身是无缝的一样。
For normal map generating purposes you don't even have to attach and weld the different sub components together, as long as they fit seamlessly you should be fine.
