I know that unreal doesn’t support this feature right now but it would be great if you can point me to a place to start. I only need this to work for uobject/aactor derived blueprints.

Cooking a single asset in C++ is essentially calling `SavePackage` with a specific cook context. To build this custom pipeline, you need to:

1. Call `BeginCacheForCookedPlatformData` on the asset for your target platform.

2. Wait for all asynchronous shader compilations and UE5 `AssetCompile` tasks to finish.

3. Call `SavePackage` using the correct `PackageWriter` to serialize the cooked data.

4. **Finally, invoke `UnrealPak`** to compress and package those saved files into an actual `.pak` or `IoStore` (`.utoc`/`.ucas`) container so the engine can mount it at runtime.

If you don’t want to build and maintain this boilerplate C++ pipeline just to update a live game, I developed a plugin called **Runtime Details** that handles this exact low-level process under the hood.

Our **Asset Hot Update** feature automatically runs this full cook pipeline for the specific asset you select, packages it, and pushes it directly to your running Packaged Build over the network.
