Can I update my map with another players map?
If I play multiplayer with a friend and we go into separate caves for example, will my map then update with what he sees as well?
Is there a way to make it do this?
Best Answer
No you're map will only be updated with whatever you see.
There is no way to do what you want with un-modded Terraria. There may be mods which will do what you want but I'm unaware of any and it's unlikely that they exist.
Each person's map file is stored in Documents/My Games/Terraria/Players/<name>, with the name of the world as a .map file. So you could open up your friends map file if you wanted to.
