Redirect log output for games using Unreal

Configure log redirection for Unreal Engine game servers.
Read time 1 minuteLast updated 3 days ago
Multiplay Hosting expects your game to output logs to a log directory directly using the 
$$log_dir$$
configuration variable. However, games using the Unreal Engine and the 
-Userdir
launch parameter output logs to a log directory nested within 
$$log_dir$$/logs/Saved/Logs/
with Unreal creating the recursive directories. Multiplay Hosting doesn't yet support traversing more than one nested log directory. To work around this, use the 
-LOG
launch parameter to redirect to a specific file: 
-LOG=../../../../$$log_dir$$/$$serverid$$.log
This causes the Unreal Engine to write to the correct directory and name the log after the specific server ID.
