Is there a default 16 player limit for multiplayer?

I’m trying to run a server over LAN and open it up to a larger group (office-wide of around 100 people). I have the project working where people can join in and spawn/possess fine and see each other, but there seems to be a limit of 16 players in the session at one time - even if i use PIE with 20 players, the last four wont join the session. I have set the public connections limit above 16 when creating the server but is there any other common setting I may be missing?

There isn’t a hardcoded limit to the number of players. Maybe check how the players are being spawned? i.e. is there only 16 player starts? or even checking if there is a variable for max connections.

I’ve tried it with more than 16 player starts and it made no difference. When starting the session with a ‘create session’ node I have public connections set to 150 and still nothing. I really can’t see what I’m doing wrong that even a PIE session cant spawn more than 16 people in a single session, even in a blank project

so I did a bit of looking into this issue and have found this in the DefaultGame.ini file. the more you know!

 [/Script/Engine.GameSession]
        MaxPlayers=16

Hope this helps!

p.s. if this is not in there create it and set the max players value to what u want.

Probably because it gets written out by the project the first time a game session is created by the AGameSession class

UPROPERTY(globalconfig)
int32 MaxPlayers;

I think that’s done it! Excellent, thank you for the help. I had a look in DefaultGame.ini initially but it didn’t have the max players line in my project, adding it manually seems to have worked. Thank you so much - do you know why that line in DefaultGame differs from project to project?
