Level "inheritance"?

I want to have a bunch of different levels (maps) that share a common core set of actors, but each level has its own unique set of actors as well.

Is there a way to configure it so that I can add or remove actors from the common core in one place without modifying every level ?

Perhaps sublevels or something?

Ideally I would like to create a “base” level that only contains the common core set of actors and then create the other levels as “subclasses” of it. If I add or remove an actor from the “base” level then it should also be automatically added/removed from the “subclass” level. Is there a way to do that?

Yes, you can do this with sublevels. Just setup sublevels that have the commonly shared items, and load them into your main levels as needed.

Ok, I’ll give it a shot, thanks.
