[Unity]URP学习记录（2）

在Shader的Inspector中，可以查看

Surface shader：URP不支持Surface shader，URP一般为no
Fixed function：固定管线（老显卡）-URP一般为no
Compiled code：编译Shader并查看代码
Cast Shadows：投射阴影
Render queue：渲染次序
LOD：LOD值
Ignore projector：忽略投影
Disable batching：禁用合批
Keywords：编译宏
SRP Batcher: compatible / not compatible（兼容&非兼容）

如果Shader中 使用了
CBUFFER_START(UnityPerMaterial)
CBUFFER_END
则兼容，反之不兼容

配置URP

一、创建URPAsset
1、URPAsset 控制项目中全局的渲染和质量配置，
以及创建渲染管线实例(rendering pipeline instance)，
渲染管线实例包含中间资源和渲染管线实现。
2、按以下步骤创建URPAsset
在编辑器Project中，Create > Rendering > Universal Render Pipeline > Pipeline Asset

二、将URPAsset配置到图形设置中
如果不配置，则Unity仍然使用内置渲染管线
1、Edit > Project Settings > Graphics
将URPAsset拖到 Scriptable Render Pipeline Settings

三、升级Shader
内置Shader不支持URP，需要进行切换
1、使用内置切换功能
Edit > Render Pipeline > Universal Render Pipeline
根据需求点 Upgrade Project Material to URP Materials 或者 Upgrade Selected Materials to URP Materials
Tips: 如果升级后Project中的缩略图错了，可以选择Reimport All
Tips: SpeedTree的Shader，需要 “Generate Materials”或者 “Apply & Generate Materils”
