Getting structure variables from another actor

I have actor that has structure variables inside it, but that object is not all the time in the world. But i need to get variables still out of that actor. How could i do it without putting that actor inside the world?

Unless you spawn it somehow, the instance does not exist - we can agree on that, right? You can still use the Get Class Defaults node:

Expose what you need and go to town with it.
