Level Streming - Extract hierarchy without activate level

Hello my friends! I have some troubles…

I have external logic editor and need to expose level hierarchy from UE world to My.Editor.
Dou you have any idea hove to do that?

I know about World Streaming tools and this mode enable save information in level header, but I use separated level’s for load (not sliced big world)
Me need something like as Prefab/Blueprint Actor, which I can load, enumerate childs, send to editor and instance on demand.

My current idea based on UE.Editor plugin, which create my hierarchy object near level, which collect level content during save. Seems like so ugly :frowning:

Thanks for any idea!
