A solution to this should be more simplistic than it is currently. I’m still looking for real solutions to having optional content in packaged games. This might be one of those things that requires digging through the engine source… (Like pretty much everything in the Unreal Universe)
EDIT:
I should add that I’m looking for a solution that involves the use of C++. I want to package my application once and add items like cars, maps, etc… dynamically. If my application’s code does not change, I don’t see a need to rebuild everything. I have not found a solution for this yet.
I don’t know why this is so difficult or why the documentation is so lacking.
