Raw inclusion of uncooked plugins/mods/DLC in a packaged game

Hi,

I have a packaged project which deliberately does not use .pak files.
How can I add a content-only plugin/mod/DLC to this packaged game without necessarily referencing the project’s uproject file? That is, I want to directly include content to a packaged game without having access to the original uproject. This may include any kind of uasset, such as a umap.

Is this possible?

Should be possible yes.
Most likely even considerably easier without PAK files.
However afaik the content still has to be cooked. But it doesn’t have to be cooked in the original project. Modder can create a new blank blueprint project from UE launcher (using same version as game’s project), make assets, cook them, then paste cooked content into the game’s content folder(s). Make sure to disable PAK files and shared shader archives in the mods projects.

One thing I’m not sure about is how the Asset Registry works when there is no PAK file. But if necessary, one call to ScanPathsSynchronous on game startup might be enough to detect stuff if it doesn’t work out of the box.
