今天和大家一起来学习一下unity2022版本新出的全屏shader graph如果在2022之前想要实现全屏shader,可能还需要自己写脚本但是在2022.2的版本之后unity将它纳入了进来。
unity2022版本 Fullscreen shader graph
首先请注意你的Inity版本是不是2022.2以上并且项目是URP项且
基本配置
紧接着我们创建一个Fullscreen shader graph 下面我们就要使用它了修改URP配置添加Full Screen Pass Renderer Feature 将我们shader相关的全屏材质给到Pass Material 这时你会发现Game视图变成了灰色
修改shader graph
创建极坐标节点分离他的输出输出的R就是中间黑四周白的渐变然后将它通过乘幂函数进行调整让黑色区域更大 我们需要将shader的Blend Mode设置为Alpha不然看不到效果 效果
边缘效果
现在我们来创建一个泰森多边形也叫沃洛诺伊图将它和我们的透明度遮罩相乘得到一个新的遮罩然后再连接给最终的透明度通道
效果
动起来
然后我们让他动起来这无疑用到了移动套装时间节点乘以一个速度然后进行偏移之后连接给Angle offset这样泰森多边形就动起来了 效果
优化
我们将最终的输出用Clamp节点限制一下范围0到1避免不必要的显示错误
黑白过渡这里太明显了我们先乘以一个较小的值处理 这里我乘以0.8然后Power指数改为5感觉这样还不错 效果
科幻风
有趣的是如果我们将泰森多边形的Cells作为输出那么我们就会得到一个科幻风的效果 效果
制作一些变量
你可以根据自己的喜好调整这些参数但为了更加方便的进行控制下面我们将制作一些变量跟着我做
颜色 接下来是指数部分他影响遮罩的范围所以定义一个float类型的变量就叫range,默认值5 乘幂之前的这个相乘的数值控制透明的力度就叫他strength 泰森多边形的大小也做一个变量就叫他Size 移动速度做一个变量叫Speed 接下来是泰森多边形的输出我们需要一个Branch分支节点来控制不同的输出这样控制Predicate是否为True,就可以控制输出了。我们也个他做成一个布尔类型的变量就叫Cells
最终效果 最终节点图 代码控制 挂载
2022之前版本 正如前面所说2022之前版本需要自己写脚本好在github上已经有大佬帮我们写好了我们不用关心怎么做的只要会用就行。 下载 Blit Render Feature 脚本
github地址https://github.com/Cyanilux/URP_BlitRenderFeature
复制Blit.cs脚本到我们本地 打不开或者嫌麻烦的复制我下面的代码就行了我已经复制过来了

using UnityEngine.Rendering.Universal;/** Blit Renderer Feature https://github.com/Cyanilux/URP_BlitRenderFeature* ------------------------------------------------------------------------------------------------------------------------* Based on the Blit from the UniversalRenderingExamples* https://github.com/Unity-Technologies/UniversalRenderingExamples/tree/master/Assets/Scripts/Runtime/RenderPasses* * Extended to allow for :* - Specific access to selecting a source and destination (via current cameras color / texture id / render texture object* - (Pre-2021.2/v12) Automatic switching to using _AfterPostProcessTexture for After Rendering event, in order to correctly handle the blit after post processing is applied* - Setting a _InverseView matrix (cameraToWorldMatrix), for shaders that might need it to handle calculations from screen space to world.* e.g. Reconstruct world pos from depth : https://www.cyanilux.com/tutorials/depth/#blit-perspective * - (2020.2/v10 ) Enabling generation of DepthNormals (_CameraNormalsTexture)* This will only include shaders who have a DepthNormals pass (mostly Lit Shaders / Graphs)(workaround for Unlit Shaders / Graphs: https://gist.github.com/Cyanilux/be5a796cf6ddb20f20a586b94be93f2b)* ------------------------------------------------------------------------------------------------------------------------* Cyanilux

CreateAssetMenu here allows creating the ScriptableObject without being attached to a Renderer Asset
Can then Enqueue the pass manually via https://gist.github.com/Cyanilux/8fb3353529887e4184159841b8cad208
as a workaround for 2D Renderer not supporting features (prior to 2021.2). Uncomment if needed.

}新增或空白阴影图Blank Shader Graph或者lit Shader Graph其实都可以 其实这一步跟前面类似不过这里只是添加我们自己定义了URP配置脚本 配置材质 如果我们想要全屏效果不希望它受处理效果的影响您可以选择After Rendering Transparents在渲染后处理效果后 但我们这里选择After Rendering Opaques 渲染不透明后因为我希望它受到后处理效果影响
修改配置shader graph 连线参考和前面一样即可
不使用shader graph
当然如果你不想使用shader graph实现全屏效果也是可以的可以参考我之前的文章 【unity小技巧】受伤屏幕闪红、死亡动画、死亡黑屏效果
