This Toon shader is configured to easily produce all shadows essential to character design, such as those that accentuate the form of various parts of a character model, without having to worry about the position and intensity of light sources. Shadow color settings can also be used to make it easy for the person responsible for color design to create shadows.
这个Toon着色器可以很容易地生成角色设计所需的所有阴影信息，比如那些强调角色模型各个部分形状的阴影，而不必担心光源的位置和强度。阴影颜色设置也可以用来让负责色彩设计的人更容易地创建阴影。
One of this shader’s particularly powerful features is the ability to adjust shadows using sliders within the shader itself, eliminating the need for multiple light sources.
这个着色器的一个特别强大的功能是能够在着色器内部使用滑块调整阴影，消除了对多个光源的需要（不需要多个光源）。

Performance was greatly enhanced in Unity-Chan Toon Shader Ver. 2.0; the same rendering capabilities as Ver. 1.0 were retained while also allowing for an even more sophisticated look.
在UTS 2中，性能得到了极大的提高。保留了1.0相同的渲染功能，同时允许更复杂的外观。

In addition to the 3 basic layers of Base Color, 1st Shade Color, and 2nd Shade Color, colors and textures can also accept a wide variety of customization options, such as High Color, Rim Light, MatCap (sphere mapping), and Emissive (light emission).
除了基本色、一阶阴影色和二阶阴影色这3个基本层之外，颜色和纹理还可以接受多种定制选项，比如高光（High Color）、Rim Light（轮廓光）、MatCap(球面映射)和Emissive(自发光)。

The level of gradation between colors can also be adjusted in Unity in real-time.
颜色之间的渐变也可以在Unity中实时调整。
[外链图片转存失败(img-YR7xzzgo-1562039279776)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UT2018_UTS2_SuperTips_13.jpg)]
This shader also has 2 options for creating fixed shadows necessary to the design: the Position Map, which assigns a set casting point to each shadow, and the Shading Grade Map, which can adjust shadow intensity based on the lighting.
这个着色器也有2个选项来创建设计所需的固定阴影:阴影位置贴图，它为每个阴影分配一个设置的投射点；阴影等级图，它可以根据光照调整阴影强度。
There are several other convenient tools for things like how visible eyes and eyebrows are through bangs, which can further emphasize an anime-style look.
还有其他一些方便的工具，比如眼睛和眉毛通过刘海的可见程度，可以进一步强调日本动漫的风格。
In short, Unity-Chan Toon Shader 2.0 (UTS2) makes a wide variety of character designs possible, from cel-shaded to light novel illustration styles.
简而言之，Unity-Chan Toon Shader 2.0 (UTS2)使各种各样的人物设计成为可能，从cel-shaded到light新颖的插画风格。
Of course, it also supports Unity’s system shadow feature.
当然，它也支持Unity的系统阴影功能。

Adding post effects allows UTS2 to use non-photorealistic rendering (NPR) to create any picture-like element that can be made with a standard shader that supports physics-based rendering (PBR).
添加后期效果（post effects）允许UTS2使用非真实感渲染(NPR)创建任何类似于图片的元素，这些元素可以使用支持基于物理的渲染(PBR)的标准着色器生成。
Several techniques have been implemented to beautifully display characters in a variety of lighting environments, thanks to recent feedback from VRChat users.
由于最近来自VRChat用户的反馈，已经实现了几种技术来在各种照明环境中漂亮地显示角色。
See for yourself by coloring your best character model with Unity-Chan Toon Shader 2.0 (UTS2).
您自己可以通过使用UTS2为您最好的角色模型着色。
You may be surprised to see your character looking better than ever before.
你可能会惊讶地发现你的角色看起来比以前更好了。
This manual focuses on the newest version of Unity-Chan Toon Shader Ver. 2.0: UTS2 v.2.0.5 Release.
本手册主要介绍UTS2的最新版本：v.2.0.5发行版。
Development Environment 开发环境
Unity-Chan Toon Shader Ver. 2.0 is developed based on Unity 5.6.3p1, and verification of compatibility with the latest versions of Unity 2018.x is ongoing.
UTS2是基于Unity 5.6.3p1开发的，并验证了与最新版本Unity 2018.x的兼容性。
(However, as version 5.6.3p1 is in the legacy pipeline, it is not currently compatible with SRP).
（但是，由于5.6.3p1版本在传统渲染管线中实现，所以它目前与SRP不兼容）
Target Environment 目标环境
Unity 5.6.x or later is required. This shader is confirmed to be compatible with Unity 2017.4 15f1 LTS. Unity 2018.1.0f2 and later versions can also be used.
This package is developed in Unity 5.6.3p1.
This package uses a forward rendering environment. Using a linear color space is recommended.
此包使用前向渲染环境。建议使用线性颜色空间。
(A gamma color space can also be used, but this tends to strengthen shadow gradiation. For more details, see Linear or Gamma Workflow. )
（伽玛空间也可以使用，但这往往加强阴影梯度。有关详细信息，请参见线性或Gamma工作流。）

Basic UTS2 Settings
For those completely new to UTS2, practicing “making a picture with Step and Feathering using only the Base Color and 1st Shade Color” is recommended, rather than immediately attempting to use all the available features.
对于UTS2的新手，建议练习“只使用基本颜色和第一个阴影颜色来制作带有分级和渐变的着色”，而不是立即尝试使用所有可用的特性。
It is important to first become familiar with the basics of UTS2, then gradually add rim lights and a 2nd Shade Color if necessary.
首先要熟悉UTS2的基本知识，然后在必要时逐渐添加轮廓光和第二层阴影颜色，这一点很重要。
Feel free to use the following video for reference while practicing.
练习时请随意使用以下视频作为参考。
Using the Different Shaders in UTS2
Opening the shader class (UnityChanToonShader) installed by Unity-Chan Toon Shader 2.0 (UTS2) shows that it contains a variety of shader files.
打开UTS2的Shader文件夹下会发现很多文件。
At this point, most users would simply close this; instead take a closer look at the various name blocks in the menu. These name blocks (Toon, DoubleShadeWithFeather, Clipping, StencilMask, etc.) are actually one of the most basic features of UTS2. This structure ensures that shaders that have the same name block as one shown in the menu will have the same features.
此时，大多数用户不需要关心它;相反，请仔细查看Shader菜单中的各种名称。这些名称块(Toon、DoubleShadeWithFeather、Clipping、StencilMask等)实际上是UTS2最基本的特性之一。此结构确保具有与菜单中显示的名称相同的着色器具有相同的特性。
Now, let’s take a look at each name block and their features.
现在，让我们看看每个名称块及其特性。
The Shaders in the UnityChanToonShader Root Folder Shaders菜单中UnityChanToonShader根目录
[外链图片转存失败(img-ACGaZqrE-1562039279778)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2_Standard.jpg)]
UTS2 shaders fall into two main categories.
UTS2着色器分为两大类。
- DoubleShadeWithFeather : The standard shader for UTS2. Allows for 2 shade colors (Double Shade Colors) and gradation between colors (Feathering). UTS2的标准着色器。允许两种阴影色(双阴影色)和颜色之间的渐变(平滑)。
- ShadingGradeMap: A more advanced UTS2 shader. In addition to the DoubleShadeWithFeather features, this shader can also hold a special map called a ShadingGradeMap. 一个更高级的UTS2着色器。除了DoubleShadeWithFeather特性外，这个着色器还可以保存一个称为ShadingGradeMap的特殊贴图。
[外链图片转存失败(img-XWnfnD1N-1562039279778)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/Comp_UTS2_Shaders.jpg)]
Both types have the same basic features, so the same look can be achieved with either type by matching the color (_Step) and gradation (_Feather) values.
这两种类型都具有相同的基本特性，因此通过匹配颜色类型/分级(_Step)和渐变(_Feather)值，可以用任何一种类型实现相同的外观。
Choosing which shader to use is a matter of personal taste, but generally DoubleShadeWithFeather is more suited to cel styles that need sharp, well defined colors, while ShadingGradeMap may be better for illustrated styles where the colors are more blurred together.
选择使用哪个着色器是个人喜好的问题，但是一般来说，DoubleShadeWithFeather更适合需要锐利的、定义良好的颜色的卡通（cel）风格，而ShadingGradeMap可能更适合颜色更加模糊的插画（illustrated ）风格。
Additionally, having Toon at the beginning of the shader name means that the shader can create outlines using the object inversion formula.
此外，在着色器名称的开头有Toon意味着着色器可以使用对象反转公式创建勾边。
Outlines in UTS2 have a lot of customization options: the strength of outlines made with dedicated textures, the level of blending with the Base Color, camera base offset, and more.
UTS2中的勾边有很多自定义选项:用专用纹理制作勾边的强度、与基本颜色的混合程度、基于相机偏移量等等。
Shader names also have name blocks such as Clipping at the end. These indicate the following kinds of features.
着色器名称也有名称块，比如末尾的裁切Clipping。这表明了以下几种特性。
- Clipping: Shader contains a clipping mask, a kind of “texture omitter” capable of things like cut outs, dissolves, etc.
裁切:着色器包含一个裁切蒙版，一种“纹理省略”，可以剪切、溶解等。 - TransClipping: Also indicates a clipping mask, but takes the mask’s αTransparency into account when omitting a texture. This allows for better omission, but creates a greater load than Clipping.
透明裁切:也是一个裁切蒙版,但考虑了蒙版的alpha 透明当作纹理省略的依据。这允许更好的省略，但是创建了比单裁切更大的负载。 - StencilMask: Uses the stencil buffer to designate how visible certain parts are through others. For example, for an anime style character it may be desirable to always have the eyebrows visible instead of covered by the character’s bangs. This shader must always be used with a StencilOut type shader.
模板遮罩:使用模板缓冲区指定某些部分通过其他部分的可见性。例如，对于动画风格的角色来说，最好总是让眉毛露出来，而不是被刘海遮住。此着色器必须始终与StencilOut类型着色器一起使用。 - StencilOut : Used together with StencilMask type shaders. In the above example, this shader would be set on the “bangs” part to make them transparent so that the “eyebrows” parts are visible.
模板去除:与StencilMask类型着色器一起使用。在上面的例子中，这个着色器将设置在“刘海”部分，使它们透明，以便“眉毛”部分可见。

The Shaders in the UnityChanToonShader/NoOutline Folder
[外链图片转存失败(img-sQ7NiKHB-1562039279779)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2_NoOutline.jpg)]
The shaders in the NoOutline folder have ToonColor at the front of their names, but here this indicates that the shader does not have the outline feature.
NoOutline文件夹中的着色器的名称前面有ToonColor，但在这里这表示着色器没有勾边特性。
Parts without the outline function will have one less drawing pass, so these shaders are ideal for designs that do not require outlines or when using high accuracy toon line shaders like PSOFT Pencil+ 4 Line for Unity.
没有勾边功能的部件将会少一个的渲染pass，所以对不需要勾边或在Unity中使用高精度卡通Line着色器如PSOFT Pencil+ 4 Line之外，这些着色器是更好的选择。

Some of the NoOutline shaders have the Transparent name block at the end of their names.
一些没有勾边着色器的名称末尾有一个透明的名称块。
These are special transparency shaders. They are useful for parts meant to have a “blush” look, or for glass and glass-like objects.
这些是特殊的透明着色器。它们适用于具有“粉红色”外观的部件，或用于玻璃和类似玻璃的物体。

The Shaders in the UnityChanToonShader/AngelRing Folder
[外链图片转存失败(img-k8xCQLRe-1562039279780)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2_AngelRing.jpg)]
The AngelRing folder contains shaders with an “angel ring” feature.
天使之环文件夹包含带有“天使之环”特性的着色器。
The “angel ring” is a highlight effect, as demonstrated in the image below. They have a fixed position from the camera’s perspective.
“天使之环”是一个高光效果，如下图所示。从透视相机的角度看，它们有一个固定的位置。
[外链图片转存失败(img-LNrNibaH-1562039279780)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/AR_Image.jpg)]
Only UTS2’s hi-spec ShadingGradeMap shaders and their variant ShadingGradeMap_TransClipping shaders have this “angel ring” feature.
只有UTS2的高规格ShadingGradeMap着色器及其变体ShadingGradeMap_TransClipping着色器才具有这种“天使之环”特性。
These shaders are primarily used in “hair” parts, which puts them in a similar category to StencilOut shaders, which are omitted by stencils.
这些着色器主要用于“毛发”部分，这使它们与模板去除着色器处于类似的类别。
The Shaders in the UnityChanToonShader/Mobile Folder
[外链图片转存失败(img-6Yhi293m-1562039279781)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2_Mobile.jpg)]
Lightweight versions of shaders, intended for Mobile and VR content, that generally won’t change the look of objects can be found in the Mobile folder.
轻量级着色器版本，适用于移动和VR内容，通常不会改变对象的外观，可以在Mobile文件夹中找到。
The following features are restricted in order to make these shaders lighter for mobile platforms.
为了使这些着色器在移动平台上更轻，限制了以下特性。
- Only one real-time directional light may be used (multiple lights and real-time point lights are also unsupported).
只能使用一个实时方向光(不支持多个光和实时点光源)。 - Point lights are supported by using baked point lights and light probes. This may require certain adjustments to GI_Intensity.
支持由点光源和光探针烘焙的点光源。这可能需要对GI_Intensity进行某些调整。
Mobile shader properties are compatible with normal Toon_DoubleShadeWithFeather shaders and Toon_ShadingGradeMap shaders, so if the above features are acceptable, mobile shaders can be substituted for their standard versions in order to improve rendering performance.
移动端着色器属性与普通的Toon_DoubleShadeWithFeather着色器和Toon_ShadingGradeMap着色器兼容，因此，如果上述特性是可接受的，可以用移动着色器替换它们的标准版本，以提高渲染性能。
The Mobile/AngelRing folder contains mobile shaders that support the “angel ring” feature.
Mobile/AngelRing 文件夹包含支持“天使之环”特性的移动着色器。
The basic features of each shader are identical to their standard version counterparts.
每个着色器的基本特性都与标准版本相同。
The Shaders in the UnityChanToonShader/Tessellation Folder
[外链图片转存失败(img-UCbuemyS-1562039279781)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2_Tess.jpg)]
UTS2 shaders that support DirectX 11 Phong Tessellation can be found in the Tessellation folder.
支持directx11 Phong细分方式的UTS2着色器可以在Tessellation 文件夹中找到。
Phong Tessellation corrects the position of subdivided surfaces so that they will be more closely aligned with the mesh’s normal vectors. It’s an effective method for smoothing low-poly meshes.
Phong细分修正了细分曲面的位置，使它们更接近网格的法向量。这是一种有效的低网格平滑方法。
UTS2 can only use Phong Tessellation with DirectX 11 in a Windows environment.
UTS2只能在Windows directx11环境中使用Phong细分。
The Tessellation/Light folder contains lightweight versions of the Tessellation shaders with the same restrictions as the Mobile shaders.
Tessellation/Light文件夹包含轻量级版本的细分着色器，具有与移动着色器相同的限制。
The rest of the folders also contain versions of the previously described shaders, with added support for Phong Tessellation.
其他文件夹还包含前面描述的着色器的版本，增加了对Phong细分的支持。
[外链图片转存失败(img-j0jkaJwe-1562039279782)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/DX11Tess.jpg)]
Adding Phong Tessellation noticeably improves the quality of outlines and other small details such as the lips.
添加Phong细分明显提高了勾边和其他小细节的质量，如嘴唇。
These shaders are primarily intended for pre-rendered content, however they also have applications in high-end VR character content with requirements such as having characters get very close to the user.
这些着色器主要用于预渲染内容，但它们也适用于高端VR角色内容，比如让角色非常接近用户。
The shaders in the UnityChanToonShader/Helper Folder

The Helper folder contains shaders that are only used to show the outline object.
Helper文件夹包含仅用于显示勾边对象的着色器。
The outline object can be applied to a character as a multi-material.
勾边对象可以作为多材质应用于角色。
[外链图片转存失败(img-RP6Ib0xG-1562039279782)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/OutlineHelper.jpg)]
Add outlines by going to the mesh’s Skinned Mesh Renderer > Materials and increasing Size by 1, then register the desired outline material.
添加勾边通过进入网格的蒙皮网格渲染器>材质大小增加1，然后注册所需的勾边材质。
Warning: The outline will be added on top of the other materials, which will increase the PC burden. Keep this in mind when using these shaders…
警告:轮廓将添加在其他材料之上，这将增加PC的负担。使用这些着色器时请记住这一点。

| Item | Function | Property |
|---|---|---|
| Stencil No | Used by StencilMask / StencilOut shaders. Designates a stencil reference number between 0 - 255 (note that in some cases 255 carries a special significance). Matches the number for the cutting material and the material to be cut. | _StencilNo |
| 模板编号 | 用于StencilMask/StencilOut 着色器。指明0-255作为一个模板编号（有些案例255会作为特殊指令）。匹配裁切材质的编号和裁切。 | |
| Clipping Mask | Used by Clipping / TransClipping shaders. Designates the grayscale clipping mask. White indicates “none”. If no settings are chosen, the clipping feature will be inactive. | _ClippingMask |
| 裁切蒙版 | 用于Clipping /TransClipping 着色器。指明灰度图作为裁切蒙版。白色代表“none”。如果没有设置，裁切特性将处于非活动状态。 | |

| Clipping Level | Designates the strength of the clipping mask. | _Clipping_Level |
| 裁切水平 | 指定剪切蒙版的强度 | |
| Transparency Level | Used by TransClipping shaders. Adjusts the transparency level by treating the clipping mask grayscale level as an α value. | _Tweak_transparency |
| 透明水平 | 用于TransClipping 着色器。调整透明度通过处理裁切蒙版灰色水平作为alpha值 | |
| Use BaseMap α as Clipping Mask | A property only found in TransClipping shaders. Checking this property will use the A channel, including the BaseMap, as a clipping mask. Designating a ClippingMask is not required. | _IsBaseMapAlphaAsClippingMask |
| 用主贴图alpha作为裁切蒙版 | 只出现在TransClipping 着色器。检查此属性将使用A通道(包括BaseMap)作为裁切蒙版。不需要指定裁切蒙版。 | |

TransClipping shaders have the same general features as Clipping shaders, but can also use the clipping mask grayscale level as an α value.
TransClipping着色器和Clipping 着色器有着一样的特性,但也可以使用剪切蒙版灰度水平作为alpha值。
These shaders are often used to cut the ends of long, straight hair using a mask which references the alpha, or for things like strands of hair that stick up out of the top of a character’s head.
这些着色器通常用于使用一个参照alpha值的蒙版来裁切掉长而直的头发的末端，或者用来剪掉角色头顶上的头发。

“Basic Three Colors and Control Maps Setups” Menu
[外链图片转存失败(img-imfoPtOx-1562039279784)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/UTS2UI_02_00.jpg)]
This Menu defines the basic colors used by UTS2: the Base Color, 1st Shade Color, and 2nd Shade Color.
These colors are arranged in order from the light source’s direction, Base Color⇒ 1st Shade Color ⇒ 2nd Shade Color.
Each color is determined by multiplying each pixel in the texture by each color, then multiplying by the light color.
每种颜色都是由纹理中的每个像素乘以每种颜色，然后乘以光照颜色确定的。
※ Hint: The Shade Colors do not have to be darker than the Base Color, and there’s nothing wrong with making the 2nd Shade Color lighter than the 1st Shade Color. In fact, doing so can give the impression of reflecting light from the environment.
阴影色不必比主色深，第二种阴影色比第一种阴影色浅也没有什么错。事实上，这样做会给人一种反射光的感觉。

The Normal Map is generally used in UTS2 for Shade Color gradation…
UTS2中通常使用法线贴图进行阴影渐变。
Using the Normal Map along with standard shading allows for more complex gradation effects. In the above image, the left side reflects the normal map in color, the right does not reflect it.
使用法线贴图和标准阴影允许更复杂的渐变效果。在上面的图像中，左侧反射法线贴图的颜色，右侧未反射它。
Besides, the normal map is used to adjust skin texture by using it together with the scale. Also, by preparing a normal map for MatCap, it is used to express hair texture.
此外，使用法线贴图和缩放一起调整皮肤纹理。此外，通过为MatCap准备法线贴图，它可以用来表示头发的纹理。

By using normal maps, you can enjoy various expressions.
通过使用法线贴图，您可以享受各种表达式。
| Item | Function | Property |
|---|---|---|
| NormalMap Effectiveness | Select whether to reflect the normal map on each color. If the button is Off, that color does not reflect the normal map but is evaluated by the geometry of the object itself. | |
| 法线贴图效果 | 选择是否在每种颜色上反射法线贴图。如果按钮关闭，则该颜色不反映法线贴图，而是由对象本身的几何形状来评估。 | |
| 3 Basic Colors | Set Active when you want the normal map to be reflected in the colors. | _Is_NormalMapToBase |
| 当您希望法线贴图在颜色中反射时，将其设置为活动状态 | ||
| HighColor | Set Active when you want the normal map to influence the high color. | _Is_NormalMapToHighColor |
| 当您希望法线贴图影响高颜色时，请设置为活动。 | ||
| RimLight | Set Active when you want the normal map to influence the RimLight. | _Is_NormalMapToRimLight |
| 当您希望法线贴图影响边缘光时，请设置为活动。 |

※ Hint: The Normal Map can also be used for pseudo-solid effects like bumps. However, the Normal Map will not actually make the surface of the object’s geometry bumpy and instead will cause the lighting to give the appearance of bumps. Therefore it is necessary to set the Base Color/1st Shade Color/2nd Shade color step so that it is easier for the light to bring out this effect. In the example above, the Base Color step is set to 0.8, the Shade Color step is set to 0.5, and a slightly darker Hi-Color is used to emphasize the object as solid.
※ 注意：法线贴图也可以用于假实体效果，比如凹凸。然而，法线贴图实际上不会使物体的几何表面凹凸不平，相反，它会使光线产生凹凸不平的效果。因此，有必要设置主色/第一阴影/第二阴影的分级，以便于光更容易产生这种效果。在上面的例子中，基本颜色分级设置为0.8，阴影颜色分级设置为0.5，稍微暗一点的Hi-Color用于强调对象为实体。
“Shadow Control Maps” Submenu
Specify the position map and shading grade map to adjust the shadow fall condition.
指定位置图和阴影渐变图来调整阴影效果。
Depending on the shader you use, the items in the sub menu will change.
根据您使用的着色器，子菜单中的项将发生更改。

The Position Map designates shadows that you want to cast regardless of the lighting.
位置贴图指定您想要投射的阴影，而不考虑光照。
It can be added to a material in addition to the lighting, for times when you want a particular shadow to show in each scene or when there are directorial reasons to add shadows.
当你想在每个场景中显示一个特定的阴影，或者有特定的原因需要添加阴影时，它可以添加到除光照之外的材质中。
※ Hint: It might be easier to draw those shadows directly using a 3D painter like Substance Painter, etc.
※提示:直接使用像Substance Painter等3D工具绘制阴影可能会更简单。
【How the 1st and 2nd Shade Color Position Maps Interact】

In order to display the 2nd Shade Color independent of lighting, make sure to fill in the places where the 1st and 2nd Shade Color Position Maps will overlap.
为了在不依赖光照的情况下显示第二阴影颜色，请确保填入第一和第二阴影颜色位置贴图重叠的位置。
This way, even if shadows from other lighting fall on the 2nd Shade Color area, it will continue to show.
这样，即使来自其他光源的照射落在第二个阴影区域，阴影仍将继续显示。
On the other hand, for areas where the 2nd Shade Color doesn’t show (areas designated by the 2nd Shade Color Position Map, but not the 1st Shade Color Position Map), the 2nd Shade Color will only show when covered by shadows created by the lighting.
另一方面，对于第2个阴影颜色不会显示的区域(由第2个阴影颜色位置图指定的区域，但不在第1个阴影颜色位置图)，第2个阴影颜色只会在被光照产生的阴影覆盖时才会显示。

【What is the Shading Grade Map?】
Toon_DoubleShadeWithFeather.shader is the basic shader in UTS2, and that shader is based on the shading grade map, which is a shading gray scale map. The Toon_ShadingGradeMap shader is further expanded to use the UV points to control shadows.
Toon_DoubleShadeWithFeather.shader是UTS2中的基本着色器，该着色器基于阴影渐变图，是一种阴影灰度图。Toon_ShadingGradeMap着色器进一步扩展，使用UV点来控制阴影。（其实前者是使用3 Basic Colors）
[外链图片转存失败(img-zPlZe6p9-1562039279788)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/0122-06_04.jpg)]
Adding the Shading Grade Map to the normal toon shader allows the 1st and/or 2nd Shade Colors to be controlled at the UV point level.
将阴影渐变贴图添加到普通的卡通着色器中，可以在UV点的水平上控制第一和/或第二种阴影颜色。
This map’s fine level of control makes effects like “hiding the wrinkles in clothes when the light hits them” possible.
这张贴图的精细控制使得“当光线照射到衣服上时，隐藏衣服上的皱纹”这样的效果成为可能。
The black portions of an image are handled by the 2nd Shade Color of the Shading Grade Map, and the way shadows fall changes based the gray portions, which depend on the density of the black portions.
图像的黑色部分由阴影渐变图的第二阴影颜色处理，阴影下降的方式基于灰色部分，这取决于黑色部分的密度。
The denser the gray, the more easily shadows fall, so shadows can also fall between two gray areas.
灰色越密集，阴影越容易落下，所以阴影也可以落在两个灰色区域之间。
Applying a shading map like the Ambient Occlusion map to the shading grade map makes it easier for shadows to fall depending on the lighting. This is useful for things like creating shadows that follow hair bangs or the concave parts of clothing.
将阴影贴图(如环境遮挡贴图)应用到阴影渐变贴图上，可以使阴影更容易地随光照的变化而下降。这对于在刘海后面或衣服的凹部创建阴影很有用。

In UTS2 v.2.0.5 we have improved the reaction of Real-time Point Light in cel-styles that doesn’t use feathering. As a result, we can create a cel-shaded look with just point lighting.
在UTS2 v.2.0.5中，我们改进了卡通渲染风格中实时点光源不使用平滑的反应。因此，我们可以创建一个只使用点光源的卡通渲染外观。
This is done by adjusting the Step slider of the Base Color /1st Shade Color, 1st Shade Color / 2nd Shade Color. With point lighting, the changes in shadows are more obvious when moving, compared to directional lighting.

By using “Step Offset”, you can adjust the Realtime light steps (the level of gradation) like point lighting that will be added to the ForwardAdd path.
通过使用“Step Offset”，您可以调整实时光照分级(渐变级别)，比如将添加到ForwardAdd 路径的点光源。
The adjustments on “BaseColor_Step” will determine the main light’s gradation but you can also use it to adjust the point lighting settings.
“BaseColor_Step”上的调整将决定主灯光的渐变，但您也可以使用它来调整点光源设置。
By using “Step Offset” at the same time, you can adjust the finer details of point lighting. In particular, this is useful when expressing highlights for machine-related art.
通过使用“Step Offset”同时，您可以调整更精细的点光源的细节。特别是，当表达与机械相关的艺术的亮点时，这是非常有用的。
The brightness of the lighting depends on how close an object is, so the highlight might be too bright in some cases, especially for the base color (bright color).
灯光的亮度取决于物体离得有多近，所以在某些情况下，高光可能太亮了，尤其是主色(明亮的颜色)。
When this happens, you can turn on “PointLights Hi-Cut Filter” to make the highlights dimmer, and make it blend in more with the cel-look.
当这种情况发生时，您可以打开“PointLights Hi-Cut Filter”，使高光变暗，并使它与卡通风格更加混合。

| The α channel of Emissive Texure | As of v. 2.0.7, the alpha channel can be used as a mask for emissive textures. Emissive is displayed at the position where the alpha channel is set to white (RGB = (1, 1, 1)) on UV basis. When black (RGB = (0, 0, 0)), the emissive disappears. | _Emissive_Tex.a |
| 从v. 2.0.7开始，alpha通道可以用作自发光纹理的遮罩。在UV的基础上，将alpha通道设置为白色(RGB =(1,1,1))的位置显示自发光。当黑色(RGB =(0,0,0))时，自发光消失。 | ||
| Emissive Animation | By making it Active, you can animate the RGB channel part of the texture specified by Emissive in various ways. Alpha channel is a mask, so it can not be animated. | EMISSIVE MODE = ANIMATION |
| 通过激活它，您可以用各种方式动画纹理的RGB通道部分。Alpha通道是一个蒙版，所以它不能被动画化。 | ||
| Base Speed (Time) | Specifies the base update speed of the animation. If the value is 1, it will be updated in 1 second. Specifying a value of 2 results in twice the speed of a value of 1, so it will be updated in 0.5 seconds. | _Base_Speed |
| 指定动画的基本更新速度。如果值为1，它将在1秒内更新。指定值为2会导致值为1的速度的两倍，因此它将在0.5秒内更新。 | ||
| UV Coord Scroll, View Coord Scroll | Specifies the coordinate system to use for scrolling. In the case of UV Coord Scroll, scrolling is performed based on the UV coordinates of Emissive_Tex. In the case of View Coord Scroll, it scrolls based on the same view coordinates as MatCap. Scrolling in the view coordinate system is very useful because it does not take into account the UV coordinates of the texture, but it is often the case that objects with flat faces like cubes can not be displayed well. On the other hand, the view coordinate system can be used very conveniently for objects with many surfaces such as characters. | _Is_ViewCoord_Scroll |
| 指定用于滚动的坐标系。在UV Coord滚动的情况下，滚动是基于Emissive_Tex的UV坐标执行的。在View Coord Scroll的情况下，它基于与MatCap相同的视图坐标进行滚动。在视图坐标系中滚动非常有用，因为它没有考虑纹理的UV坐标，但通常情况下，具有平面(如立方体)的对象不能很好地显示。另一方面，视图坐标系可以非常方便地用于具有许多表面(如角色)的对象。 | ||
| ColorShift with Time | By setting it to Active, the color multiplied to the Emissive texture changes by linear interpolation (Lerp) toward Destination Color. When using this function, it is better to set the Emissive texture to grayscale and design the each colors on the color side to be multiplied. | _Is_ColorShift |
| 随着时间的推移颜色变化 | 通过将其设置为活动，颜色乘到发射纹理变化通过线性插值(Lerp)向目标颜色。使用此特性时，最好将发射纹理设置为灰度，并在颜色面上相乘颜色。 | |

How to create a texture with alpha channel
Texture with alpha channel is created with DCC tools such as Photoshop.
纹理与alpha通道是用DCC工具，如Photoshop创建的。
You can use it as an alpha channel by adding a new channel from the channel tab and pasting a grayscale image on the created channel. If you use an image format that has an alpha channel such as Targa format, you can save as it is.
您可以通过在channel选项卡中添加一个新通道并在创建的通道上粘贴灰度图像，将其用作alpha通道。如果使用具有alpha通道的图像格式(如Targa格式)，则可以按原样保存。

To enable the alpha channel on Unity, set Alpha Source to Input Texture Alpha in the Import Settings of each texture.
要在Unity上启用alpha通道，可以将alpha Source设置为在每个纹理的导入设置中输入纹理alpha。
In the case of PNG format can not have an alpha channel directly in the image specification, so after loading an alpha channel as a selection range in Photoshop, specify “Layer mask> Mask outside selection range”, PNG Save in format.
PNG格式在图片描述中没有直接的alpha通道，因此在Photoshop中想要加载alpha通道作为可视范围，需选择“图层蒙版>从透明区域”，（然后就建立了一个新alpha通道，编辑），然后保存为PNG格式。
Then import it into Unity, and in Import Settings, set Alpha Source to Input Texture Alpha and Alpha Is Transparency to ON.
然后将它导入Unity，在导入设置中，将Alpha Source设置为输入纹理Alpha, Alpha透明度设置为ON。
Tips for setting Destination Color
When using the color shift function, set Destination Color as the target, but if the original color and the target color have the same hue, unexpected colors may be mixed into the frame. For example, if you shift from the color shown on the left side of the arrow to one of the two colors on the right that looks similar, the first color on the right of the arrow shifts color within the same hue range. The second color is a mixture of bluish frames.
当使用color shift特性时，将目标颜色设置为目标，但是如果原始颜色和目标颜色具有相同的色调，可能会将意想不到的颜色混合到框架中。例如，如果您从箭头左边显示的颜色移动到右边看起来相似的两种颜色中的一种，箭头右边的第一种颜色将在相同的色调范围内移动颜色。第二种颜色是蓝色框架的混合。
[外链图片转存失败(img-azTFG0Oy-1562039279798)(https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/raw/master/Manual/Images_jpg/DestColor00.jpg)]
This is because the color that mixes blueish frames has a B channel that has a higher value when compared to the RGB of the original color.
这是因为混合蓝色帧的颜色有一个B通道，与原始颜色的RGB相比，该通道的值更高。
In this way, when shifting colors with different luminance within the same hue to the target in this way, by aligning the direction of change of each RGB, it is possible to prevent unexpected colors from entering the frame.
这样，当将同一色调内不同亮度的颜色以这种方式移动到目标时，通过调整每个RGB的变化方向，可以防止意想不到的颜色进入帧内。

The object spawned for the object’s outline is drawn with front culling, so when it is overwritten by the original object, the parts that do not fit becomes the outline.

| Outline Mode | Specifies how the inverted-outline object will be spawned. You can choose between Normal Direction（normal inverted method） / Position Scalling（position scaling method). In most cases, Normal Direction is used but if it is a mesh that is only made of hard edges (such as cubes), Position Scalling will prevent the outline from being disconnected. It will be good to use Position Scalling for simple shapes and use Normal Direction for characters and things that have complicated outlines. | _OUTLINE |
| 指定如何派生反向勾边对象。你可以选择法线方向(法线反向方法)/位置缩放(位置缩放方法)。在大多数情况下，使用法线方向，但如果它是一个网格，只有硬边(如立方体)，位置缩放将防止勾边断开。对于简单的形状使用位置缩放，对于角色和具有复杂勾边的东西使用法线方向是更好的选项。 | ||

Normal maps that can be used as Baked Normal for Outline are as follows.
- Does not overlap with the UV of the object that it will be applied to. This means that it is essential that UV expansion and all
normals maps will not overlap.
不与它将被应用到的对象的UV重叠。这就意味着UV扩展和所有这些都是必不可少的法线图不会重叠。 - Normal maps are based on OpenGL, as Unity is.
- The texture settings of normal maps are as follows:
・Set Texture Type to “Default” . Note: Do not set this to “Normal Map”
・Make sure that sRGB (Color Texture) is turned “OFF”.
For more please check the assets in the Baked Normal folder of the sample project.
Note: This kind of vertex normal adjusting is done by the vertex shader, so it will depend on the number of vertices that it will be applied to. This means that it does not correct the vertex normals like pixel shader, so please be careful.
注意:这种顶点法线调整是由顶点着色器完成的，所以它将取决于它将应用到的顶点的数量。这意味着它不能纠正顶点法线，如像素着色器，所以请小心。

| Unlit Intensity | When there is no real-time directional light in the scene, the scene’s brightness and color will be determined by Environment Lighting’s Source Settings, boost it by Unlit Intensity and use it as a light source (This is called Ambient Blending). The default is 1 and 0 is to turn it off completely. This is used when you want to have the environment color blend with the material color, but if you want it to be a darker blend, set it to 0.5～1 and if you want it to be a lighter blend, set it to 1.5～2. (From v.2.0.6, the maximum value has become 4.) | _Unlit_Intensity |
| 无光照强度 | 当场景中没有实时方向光时，场景的亮度和颜色将由环境光的光源设置决定，通过非光照强度提高亮度，并将其用作光源(这称为环境混合)。默认值是1,0是完全关闭它。这是当你想要使用的环境颜色混合到材质的颜色,但是如果你想要一个更暗的混合,将其设置为0.5 ~ 1,如果你想要一个更亮混合,将其设置为1.5 ~ 2。(最大值由v.2.0.6变为4)。 | |
| SceneLights Hi-Cut Filter | This will minimize overexposure when the light intensity is too high, or when there are multiple real-time directional lights, or multiple real-time point lights. By turning this one you can maintain the light colors and its attenuations while only cutting the intensity of the material color to avoid overexposure. The default is OFF. When using this function, please make sure that the basic 3 colors are Active in “LightColor Contribution to Materials” menu. We recommend VRChat users to turn this on. Hint: If overexposure still occurs even when this is turned on, please check the post-effect bloom settings. (In particular, when Bloom’s threshold value is under 1, it is easier to happen.) | _Is_Filter_LightColor |
| 场景光照高光剔除过滤器 | 这将最大限度地减少过度曝光时，光强度过高，或当有多个实时定向灯，或多个实时点灯。通过开启这个选项，你可以保持光照颜色和它的衰减，同时只削减过度曝光的材质颜色的强度。默认为关闭。使用此功能时，请确保在“LightColor Contribution to Materials”菜单中基本的3种颜色是激活的。我们建议VRChat用户打开它。提示:如果开机后仍有过度曝光现象，请检查后期效果Bloom设置。(特别是当Bloom的阈值小于1时，更容易发生。) | |
| Built-in Light Direction | For experienced users, you can activate the Built-in Light Direction’s vector (the vector of the virtual lights in the shader). When this is activated, the intensity and color of the light will follow the real-time directional light’s values within the scene. If there aren’t lights like that, the values for ambient blending will be used。 | _Is_BLD |
| 对于有经验的用户，您可以激活内置的光方向向量(着色器中虚拟光的向量)。当这被激活，光的强度和颜色将遵循实时定向光在场景中的值。如果没有这样的灯光，则使用环境混合的值。 |
Adjusting the ambient blending：Unlit Intensity
The ambient light settings are now reflected in the light colors. The minimum intensity of the directional light is the setting of the scene`s ambient light.
环境光设置现在反射到光照颜色中。方向光的最小强度是场景环境光的设置。
In VRChat, the brightness of ambient light can be adjusted with the Unlit_Intensity slider.
在VRChat中，环境光的亮度可以通过Unlit_Intensity滑块进行调节。
Unlit_Intensity boosts the brightness of the ambient light.
Unlit_Intensity 提高了环境光的亮度。
The default is 1.
If there is no directional light in the scene, the default light that is included in the shader is used, and the direction is always according to where the camera is.
如果场景中没有方向光，则使用着色器中包含的默认灯光，并且方向总是根据相机的位置来确定。
As a result,lighting is always good where the camera is pointed at.
因此，相机对准的地方光线总是很好。
This light will function when the ambient light is blended.
当环境光混合时，这种光就会起作用。

Adding Built-in Light Direction as an advanced feature
As an advanced feature for experienced users, you can now set the light direction vector that is built into the shader. Materials that have Built-in Light Direction activated can have their own light direction vector for shading purposes which is independent of the mesh object’s coordinates. This means that it will have the same effect as having an exclusive fixed light.
作为资深用户的高级功能，您现在可以设置内置在着色器中的光方向向量。有内置光方向激活的材质可以有自己的光方向矢量用于阴影的目的，这是独立于网格对象的坐标。这意味着它将具有与具有唯一固定光相同的效果。
The drop shadow of this part will be used for the directional light in the scene so you can also change how shading and drop shadows look. To set the light color of Built-in Light Direction, use the main directional light settings of the scene.
这部分的阴影将用于场景中的定向光，因此您还可以更改阴影和阴影的外观。要设置内置灯光方向的灯光颜色，请使用场景的主方向灯光设置。
Please watch this video about how to use Built-in Light Direction.

Using it for visuals（pre-render） 用于图形处理（预渲染）
If you are using it pre-render, disable Anti_Aliasing in Image Effects and minimize things that were output with 4K frame capture to the suitable size. It will look better. (This is practically super sampling)
如果使用预渲染，请在图像效果中禁用抗锯齿，并将4K帧捕获输出的内容再最小化到合适的大小。它看起来会更好。(这实际上是超级采样)
Frame Capturer is provided here: Frame Capturer
You can use what you have output from frame capture in NUKE and AfterEffects.
You can also use Alembic Importer/Exporter for videos. Alembic
