Cooking Profiling可以用来查打包过程中Cooking打包过程为什么慢的问题。 可以用Unreal Insights来看。

官方虽然有一个文档，但是写的不清不楚的，一直没弄明白该怎么跑起来。

参考：Unreal Cooking Insights in Unreal Engine 5 | Unreal Engine 5.2 Documentation

摸索了一下，参考了Unreal Japan的一篇文章¹，才弄明白: 在Editor下Cook是没办法看到Cooking Insights的，需要从命令行拉起UnrealEditor-cmd.exe来Cook资源

参考脚本

1. 先打开UnrealInsights, UE4Editor-Cmd.exe拉起来的时候会反向链接UnrealInsights
2. 按照下面的脚本拉起命令行编辑器来Cook资源，对应路径需要自己调整

UE4

set ENGINE_PATH="D:\Release-4.27\Engine\Binaries\Win64\UE4Editor-Cmd.exe"
set PROJECT_PATH="D:\Projects\ShooterGame\ShooterGame.uproject"
set COMMAND=-tracehost=localhost -trace=cpu,cook,loadtime,savetime,log -ini:Engine:[ConsoleVariables]:cook.displaymode=2 -statnamedevents
%ENGINE_PATH% %PROJECT_PATH% -run=cook -targetplatform=WindowsNoEditor %COMMAND%

UE5主要是 targetplatform 有点不同。

UE5

set ENGINE_PATH="<UEEditor-CMD.exe>"
set PROJECT_PATH="D:\Projects\ShooterGame\ShooterGame.uproject"
set COMMAND=-tracehost=localhost -trace=cpu,cook,loadtime,savetime,log -ini:Engine:[ConsoleVariables]:cook.displaymode=2 -statnamedevents
%ENGINE_PATH% %PROJECT_PATH% -run=cook -targetplatform=Windows %COMMAND%
