Did you find a solution for this? I’m also trying to find a good way to separate DLC from main pak. UnrealPak and your examples on other threads helped A LOT!
But I can’t figure out how to pak and load Blueprints, even though they’re children of a C++ class. And the Release/DLC packaging from Project Launcher is not working. It seems that without a .umap, nothing goes into the resulting pak of the DLC. Even when the plugin Content folder contains Textures, SkeletalMeshes and Materials.
