大家好，我是阿赵。
之前我写了一些关于Unity可视化Shader编写工具Amplify Shader Editor（简称ASE）的使用介绍的文章。有不少网友给我留言，内容主要有2点：
- 怎么我的Unity里面没有ASE插件？
- 为什么要用ASE？用ShaderGraph应该会更好？
我个人的看法，使用什么工具是次要的，理解思路和算法才是更有用的东西。不过不同的工具也的确有它们不同的优缺点，下面我从各个方面稍微对比一下。文章比较长，各位也可以直接跳到最后面看总结。
一、插件的总体情况
ShaderGraph和ASE这两个工具，都是提供了可视化的Shader编写的功能，其中ASE是第三方插件，是需要在AssetStore上付费购买的
而ShaderGraph是Unity官方出的可视化Shader编写工具，是免费的，可以通过PackageManager免费下载。
如果没有两者都深入了解的情况下，我觉得大多数用户会选择ShaderGraph，原因有2点：
- 官方出品，理论上会更可靠，并且可以得到持续的维护。
- 免费。
第一点我是比较认同的，官方出品的东西，当Unity出了新版本，有新的渲染功能的时候，ShaderGraph是可以更好的适配新功能。
ASE暂时来说还是在不停的维护，从AssetStore的购买页面看：
我写这篇博客的时间是2024年11月27日，也就是ASE最新一个版本是在2周前发布的。不过说不定某一天ASE突然不继续维护更新，也是有可能的。
第二点也很重要。ASE卖40美元，也就是不到300元人民币，可能大家出去玩一天都不止花这点钱。但收费就是原罪。
接下来先抛开持续维护和是否收费这两点，只是对比一下两个插件的使用方面的区别。
二、 版本通用性
1、 ShaderGraph
ShaderGraph作为一个Unity官方插件，在不同的Unity版本里面，它可以使用的版本是不一样的。
Unity2019：
可以使用的ShaderGraph版本为7.7.1
Unity2022：
可以使用的版本为14.0.11
Unity6：
可以使用的版本为17.0.3
其中不同版本的ShaderGraph差别还是比较大的。
1.对Unity内置渲染管线的支持
Unity2019的版本，ShaderGraph是只支持SRP渲染的，Unity内置渲染管线是不支持的。
所以如果不是使用URP或者HDRP，在Unity2019是不能使用ShaderGraph的，在创建的时候，没有BuiltIn的选项：
如果在内置渲染管线里面创建ShaderGraph，就会不能使用
在Unity2021.2版本之后，ShaderGraph开始支持Unity内置渲染管线了。在创建的时候，有BuiltIn的选项：
如果切换到URP渲染管线，就会有对应URP的选项：
2.查看生成Shader的功能
2019版本的ShaderGraph，是没有查看生成Shader的功能的：
而后续的版本是有查看生成Shader的功能：
这个功能还是很重要的，生成出来我们熟悉的Shader，我们可以优化，也可以学习里面的一些算法。
3.Master节点
节点功能，2019版本和后续版本也不一样。
2019版本是有Master节点的
可以创建多个最终输出端。但实际上ShaderGraph是不允许这样做的。
在后续的版本里面，Master节点就被取消了：
2、 ASE
1. 版本的区别
我使用了同一个版本的ASE，在Unity2019/2022和Unity 6里面使用，结果是完全一样的。
由于ASE生成的是Unity的标准Shader文件，所以除非某个版本Unity对Shader的API进行比较大的修改，不然按道理ASE生成的Shader都可以正常使用。
2. 对各种渲染管线的支持
有一些朋友问我ASE是不是不支持SRP渲染管线？其实ASE都支持
只是默认安装的时候，会只导入了Built-in的package，而URP或者HDRP之类的渲染管线是有单独的package包的，可以自行按照需要导入。
比如我导入了URP的包，就在创建Amplify Shader的时候，就会出现Universal的选项了。
ASE还会带有一些例子，可以从里面学习一些Shader的制作方法。
三、 操作方式
1、 变量的定义
1. ShaderGraph
在ShaderGraph里面，变量是需要先定义才能使用的，并且可以作为暴露的输入参数。
定义完的变量可以拖动到编辑界面里面，变成一个节点。
不同的节点有不同的属性面板
2. ASE
ASE的参数是不需要先定义的，可以直接在编辑界面创建对应类型的节点。然后可以在节点上或者属性面板上决定参数是否暴露成可外部修改的：
在决定了那些是Property参数之后，可以在Shader总属性里面设置参数的顺序：
所以ASE在变量的声明方面是比较自由的，但没有ShaderGraph那种先定义后用那么严谨。
2、 节点的操作
不论是ShaderGraph还是ASE，对于节点的操作都是很类似的，都是在节点的输入和输出端连线，区别不大。下面是同一个边缘光的效果使用两个不同编辑器的连接情况：
ShaderGraph：
可以看到，ShaderGraph是严格遵循顶点/片段着色器程序的写法，有很明确的顶点程序输出和片段程序输出。
ShaderGraph每个节点都有预览功能，也可以单独添加一个Preview节点进行预览。
如果不需要连线了，可以选择连线，鼠标右键，选择Delete。
ASE：
整体的连接方式ASE和ShaderGraph是很类似的，不过输出节点并没有很严格的遵循顶点/片段着色器程序来连接，而是根据选择不同的Shader类型，有不同的输出通道。
和ShaderGraph的Preview节点功能一样，ASE的Relay节点也是纯预览功能。
当不想要连线的时候，ASE只需要把线从接口处移开就行了。
3、 节点整理
1. ShaderGraph
ShaderGraph可以把需要打成组的几个节点框选，然后选择Group Selection或者快捷键Ctrl+G，把这些节点打成组：
还可以给组输入名称，然后整个组可以一起整体拖动：
可以插入注释的节点：
会产生一个类似便签纸一样的节点，在上面写入自己想要的备注：
在连线上双击，可以给连线加入一个控制节点，控制连线的形状：
如果不想要这个控制节点，选中它，然后按删除键即可。
2. ASE
ASE同样有打组功能，把需要的节点框选：
然后按快捷键C，就会把节点打组，并且可以输入打组的名字和备注：
还可以给组设定不同的颜色。
然后双击连线，同样可以创建出控制点，用于调节连线的形状和位置：
当不需要控制点时，选择控制点然后按删除键就可以删除。
ASE还有一个比较好用的功能，注册本地变量，可以创建一个Register Local Var节点(快捷键R)把某个计算好的值注册到一个变量去：
然后想使用的时候，创建一个Get Local Var节点(快捷键G)，就可以选择之前注册过的变量直接拿来使用了：
通过ASE的这些整理和注册的功能，可以把一个复杂的Shader连线得比较的优雅而且清晰，并且可以控制变量的结果不需要重复计算就能重复使用：
4、 快捷键
1. ShaderGraph
ShaderGraph的快捷键比较少，比如可以按空格键快速的调起创建节点的搜索框：
还有之前说过的Ctrl+G对节点进行打组。似乎没有了。
2. ASE
基本上每一个数字或者字母，都是一个快捷键，涵盖了大部分的常用操作。
比如按1可以生成float节点，按2可以生成Vector2节点，按3可以生成Vector3节点，按A可以生成Add节点，按D可以生成Divide节点，按O可以生成One Minus节点，等等……
这些快捷键是非常方便的，在熟练之后，可以快速的创建自己所需的节点并且连线，体验是非常的好。
5、 复制节点
1. ShaderGraph
在同一个Shader的编辑器里面，ShaderGraph可以正常的复制节点：
如果跨项目复制
整体的节点还是能复制过去的，但由于ShaderGraph是先注册变量再使用，所以：
定义的变量的节点，就丢失了。
2. ASE
ASE是可以完全跨项目复制节点的，甚至跨版本都没有问题，比如我从Unity6版本的项目复制节点到Unity2022，同样可以：
6、 复制Shader
1. ShaderGraph
ShaderGraph生成的文件是.shadergraph文件
如果把shadergraph文件复制到一个没有安装ShaderGraph的项目里面：
会发现是不能识别，如果一定要复制到别的项目使用，要先View Generated Shader，查看生成的标准Shader文件，然后再拷贝到别的项目使用。
2. ASE
ASE生成的就是标准的Shader文件，所以不存在这个问题，可以直接拷贝到任意项目使用，不需要目标项目也安装了ASE。当然，如果目标项目没有安装ASE，那么将不能打开ASE的节点编辑器继续编辑，仅此而已。
四、 生成代码整洁度
下面来看看，同一个边缘光的效果，生成的代码：
1、 Built-In
1. ShaderGraph
Shader "Shader Graphs/RimColor"
{

{
_min("min", Range(0, 1)) = 0
_max("max", Range(0, 1)) = 0
