How to make a reference to a blueprint?

Hello, the question is the title, how to make a reference to a blueprint to communicate with him ?

Do you mean casting? if so, casting is used for accessing other blueprints in your current blueprint, except for the level blueprint i believe, if thats what you want you should look up a tutorial, casting is not difficult and its not a long process so dont worry

No, I use another issue but I’ll try casting tank’s

I would like the results when your done, i hope i can help you
