I need it for my game, how can i unlock it ?
Hey
When you develop and package a game for shipping, you wouldn’t want the consume to be able to access the commands in game. Therefore, the console commands are disabled when created for shipping by default. You are able to override this if you change the code within the project.
Here is a link to our Unreal Engine Documents regarding compiling game projects. Hopefully within the document, you’ll be able to shed some light on changing the code for your project.
Keep in mind that if you personally need to access the console commands, you can build your game in development instead and work from there.
If you have any further questions, please reply back to this thread. Have a wonderful day! 
Thanks for the detailed answer
I would of be just fine with development build, the problem is that i can pack 32bit version only as shipping package, and not all of the users have 64bit operating system.
Btw making the shipping version 32bit only doesn’t limit the game to 4gb of ram ?
Hey
In the editor from the Launcher, you can package for development in 64-bit and package for shipping in 32-bit. If you want to package for shipping and/or development in both 32-bit and 64-bit, you can obtain the editor from GitHub. Below is a link on how to obtain GitHub: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
I’m not quite sure what you mean regarding the 32-bit version of a shipped package limited to 4gb of ram. However, there is less memory used in a 32-bit project therefore, it would be a smaller packaged project than that of a 64-bit. So less memory overall should be used on a 32-bit project being played on a computer as opposed to a 64-bit project.
If you have any further questions, please let me know!
Cheers!
