Sure,
I’m trying to add new areas by extra paks, like DLC. (word partitions layers / streamed level / or any other way)
So the idea is use the modular game features to prepare separate levels that can be loaded on the main level.
With the Valley of the Ancient, they is away with stream levels, but at that time it was announced that there will be better solutions in the future, with official support. Now in 5.3 we have this “add world partition content”, that I guess is they way to go with level streaming in the world partition system.
But there is no documentation about it or the component that it uses the " Content bundle descriptor"
