Global Default Server Game Mode set to None fails to cook content

Not sure if this is intentional or not, but when Global Default Server Game Mode is set to None in Project Settings, the project will fail to cook content.

Hi Apoc,

Thank you for reporting this, I am attaching this and my own findings to a bug report to be assessed. Have a great day!

I’m having the same problem, did you find the solution?

Hi fireapache,

This is still being assessed by developers to find an adequate solution. Thank you for your patience!

I just had the same problem. Reading logfile cook.txt and the realtime output log in editor when packaging… I have no idea how Apoc (original poster) managed to discover that this had anything to do with the Global Default Server Game Mode setting but changing it from None to a game mode fixed it. It now packages succesfully.

I have a C++ FPS template and the builds/packaging started failing after I imported the community driven VR template and changed my gamemode, playercontroller, character…etc to those specific Blueprint assets.

As said below, I have no idea how you made the connection between this error and the Global Default Server Game Mode setting, but changing this setting fixed the problem for me too. Thanks for sharing!

I just had this exact problem, thanks for finding the solution.

For those like me which didn’t see how to set the “Global Default Server GameMode”.
There’s a tiny dropdown arrow below “Default Modes” in Project settings.

@pierre - thanks for telling us where this option was - i had a hell of a time figuring out where this option was

Many thanks for finding the solution to this issue. Really frustrating nasty problem since there is no really indicator in the output log and cook log of what went wrong.

I’m certain there are even more people out there who struggle with this issue.
