Dedicated server for blueprint based game?

Is it possible to build a dedicated server for a blueprint based game? If so how do the RPC’s get called since one is based on C++ and the other is blueprints?

You can create and join sessions with blueprints, and this does not require a dedicated server. Pardon me if you look for something else, just wanted t point this out.

I know you can do that with blueprint. Just wanted to know about the dedicated server.
