I've been making content on Youtube for Vintage Story for a little bit now and I think it would be fun to do a series showcasing the builds of anyone in the community that would interested in having their builds shown off. Is there a way for anyone to share their world with me to tour at my own pace, or would it be a matter of them inviting me into their world and doing it that way? Would that even be possible or does a world have to be created as multiplayer from the jump? Any insight on how this works and any ideas about the best way to do something like this would be greatly appreciated.
