Unreal Cooking Insights

An overview of profiling your package data using Unreal Cooking Insights

Unreal Cooking Insights provides you with the ability to gather and display information about the way packages are cooked in your project. Large cooking times can significantly affect the productivity of teams that are working on larger projects. By showing the times it takes to cook each package, this tool can help reduce cooking times.


You can run a trace for cooking insights from the command line by using the command:


Alternatively, you can run the following command to target a specific host and platform:

    MyProject -run=cook -log -trace=default,cook -tracehost=localhost -targetplatform=Windows

When loading a trace that contains cook data, the Packages table will be populated with the load time, save time, and cooking time for each package when the analysis is complete.
