I’m agree with you. I would like to play in local, save my character and join some friends on hamachi. Actually, as u said, a tons of games saved client’s save on server side and if the server are not online u can’t play with your character.
Someone tell me to take a look on outsite database. but i’m not sure how it’s work with blueprint only. It seems to be hard to use with blueprint. There is a nice free plugin Va Rest Plugin " that makes REST server communications simple to use with full Json query support "
still as complicated for me even with the plugin.
