Structure and goals of the book.
这本书的结构和目标

这本书不仅面向刚开始接触SD和SP的美术，还面向已经在实际工作中使用的中上级美术。
This book is not only for the fine arts who are new to SD and SP, but also for the intermediate and advanced arts that have been used in actual work.

除了用单纯的节点制作贴图的方法外，还包含次时代游戏工程或近期手游开发相关各种学习内容。
In addition to the simple method of making textures with nodes, it also includes various learning content related to game engineering of the next generation or recent mobile game development.

有些是作者在中国开发公司上班时用的工程，有些内容是改善了 Substance 中国大会，UNITE 等地方发表过的内容。
Some are projects that the author used when working at a Chinese development company, and some are improvements that have been published in Substance China, UNITE and other places.

这本书最根本的目标是为了扩大自己可以研究的领域。此内容为了让读者充分理解实时渲染的常识，法线贴图的演算等内容，没有写得很乏味。在写这本书的时候，没有为了写书而写案例，而是用实际工作的可视性案例，不加修饰的叙述出来。

The fundamental goal of this book is to expand the fields that one can study. In order to allow readers to fully understand the common sense of real-time rendering, the calculation of normal maps, etc., it is not tedious. At the time of writing this book, no case was written for the sake of writing the book, but the visual case of the actual work was described without modification.

About terminology 关于用语标记

比如会写成“使用SD的Texture baker”
Substance Painter 也会写成 SP。
比如会写成“可以做SP专用笔刷”
内容里的英文用语只用英文写出来，而不是用外来发音形式。
比如“SD或者SD shader语言是用GLSL写的。”会写成“SD或者SD Shader Language 是用GLSL写的”。
电脑用语的中文单词为了便于理解会用括号的形式标注英文。
比如会写成“属性定义（Define）”，或者像“转换成 Normal map”这种英文混用文章。
这本书是在  Windows 10 环境写的。
没有用SD 或者 SP 的 MAC(OSX) 环境快捷键。
所有 Filter 的名字会用原英文名字。
写书的过程中更新的 Filter 功能或追加功能会以附录的形式添加在书的后页。

For example it would be written as “Texture baker using SD”
Substance Painter is also written as SP.
For example, it would be written as “can be used for SP brushes”
The English words in the content are written only in English, not in foreign pronunciation.
For example, “SD or SD shader language is written in GLSL.” Would be written as “SD or SD Shader Language is written in GLSL.”
Chinese words in computer terms are written in English in parentheses for easy understanding.
For example, it will be written as “Define” or a mixed English article like “Convert to Normal map”.
This book was written in a Windows 10 environment.
There are no MAC (OSX) environment shortcuts for SD or SP.
All Filter names will use the original English names.
The updated Filter function or additional function during the writing of the book will be added as an appendix on the back page of the book.

About software version
关于软件版本

在协议页面打钩同意选项后点击下一步。
Check the agreement option on the agreement page and click Next.

建议储存在基本路径下。如果大家的电脑 C 盘是 SSD，Allegorithmic 的软件建议尽量安装在 SSD 上。
SP  或 SD 的滤镜和节点连接后的部分效果会储存成 Cache ， 通常 Cache 用高速硬盘会好点。

It is recommended to store under the basic path. If your computer’s C drive is an SSD, Allegorithmic’s software recommends installing the SSD as much as possible.
Some of the effects of the SP or SD filters and nodes are stored as a cache. Usually, high-speed hard drives are better for the cache.

在桌面生成快捷键，然后下一步。

Generate shortcuts on the desktop, and then the next step.

经过自动安装过程后 SP装好了。如果安装了老版本的 SP ，这个版本就自动 Uninstall。

After the automatic installation process, the SP is installed. If an older version of SP is installed, this version is automatically uninstalled.

打开确认。这是打开空白工程的 SP 页面。因为作者已经激活了软件，所以跳过了 Allegorithmic 原有的 3种认证窗。通常第一个认证激活选项是30天体验版。

Open confirmation. This is the SP page for opening a blank project. Because the author has activated the software, Allegorithmic’s original 3 types of authentication windows have been skipped. Usually the first certification activation option is the 30-day trial version.

SD 和 SP 的案例是基于 Substance designer 2017 和 Substance painter 2017 制作并储存的。如果案例使用的 Filter 是用 Substnace share 获取的话，为了保护著作权只提供 Substance share 的下载链接。

SD and SP cases were created and stored based on Substance designer 2017 and Substance painter 2017. If the filter used in the case is obtained using Substance share, only the download link of Substance share is provided for copyright protection.

制作 Substance 专用 Shader

这本书使用了 GLSL 语言来解说 Shader 的编写和修改。SD 或者 SP 的 Shader Language 是用 GLSL 写的。为了定义(Define)外部属性，和Shader通信，使用 XML 类型的 Container 。这本书对除了 GLSL 以外的 Unity Surface shader 语法或 Context 只会简单说明，但是会在索引提供可以参考或者可以学习的更正确的文献。
Shader 编辑工具会用 Visual studio Code 。
Visual studio Code 是微软提供的免费 IDE。
https://code.visualstudio.com/
写 Shader 代码时，为了 Syntex highlighting 要安装扩展功能。
下载Shader 代码扩展功能。
https://marketplace.visualstudio.com/items?itemName=slevesque.shader

This book uses the GLSL language to illustrate the writing and modification of Shaders. The Shader Language for SD or SP is written in GLSL. In order to define external attributes and communicate with Shader, use XML type Container. This book will only briefly explain the syntax and context of Unity Surface shader other than GLSL, but it will provide more accurate references that can be referenced or learned in the index.
Shader editing tools use Visual studio Code.
Visual studio Code is a free IDE provided by Microsoft.
