Without trying it myself to see (not at the editor at the moment), I can’t say for sure… but you should be able to expose those variables either with the little “closed eye” to the right of them, or down in their details there should be an “expose variable” check box… Once that’s done, I would think you can do a “get” on them in other blueprints, since they should become global to the level…?
If that’s what you tried and it doesn’t work, then I’m not sure. I could try to play with that when I get back to my comp… unless someone else answers first
