Referencing a variable from the level blueprint in another blueprint?

I have a bool in my level blueprint. I want to be able to check the value of this bool in my character blueprint.

Blueprint interfaces, which is what I would normally use, don’t seem to be supported in the level blueprint (there is no interface category in the Blueprint Props of a level blueprint).

Blueprint communications don’t seem to work either. The moment I add in the level blueprint as a class variable I get an error preventing me from saving the blueprint.

Is level blueprint communication not supported or am I missing something here?

Check out Communication level in Content Examples. Maybe you can get around by calling an event inside the Level Blueprint that will itself call an event inside your blueprint which would pass that bool as a parameter.

Good suggestion. I checked out that level and it had a lot of helpful examples. It made me realize I could just do a cast to my character class after my overlap trigger goes off. Thanks!
