在之前的文章中我们学习了 ShaderLab 中 BuildIn Render Pipeline 下的Shader书写。在这篇文章中我们来了解一下 URP 下 的最简Shader怎么编写。 一、 我们先了解一下 Shader Graph 怎么操作
1、了解一下 Shader Graph 的面板信息 2、修改Shader路径 3、鼠标中键 或 Alt 鼠标左键 移动画布
4、鼠标右键 打开创建节点菜单 5、把ShaderGraph节点转化为 Shader 代码
可以直接 查看 或 复制 编译后的Shader
6、可以看出 URP 和 BuildIn RP 大体框架一致 二、把ShaderGraph转化后的 Shader 只保留最基础的通用前向渲染Pass
因为是由ShaderGraph转化过来的。所以这里虽然简化了。但是还是过于臃肿在之后的文章中我们来优化一下

}1、我们看一下 URP Pass不可用后使用的默认Shader
使用的是内置渲染管线返回颜色为洋葱紫
