Hi, Im having issues with this program. I understand that I was to use this program to export to a file on my computer to play and have others play if I sent the file over via email etc… Im using UDK 4 and Unreal Frontend on an I Mac. Looking forward to help! Thanks 
Hello Matt,
We have some documentation on Unreal Frontend found here: Using the Unreal Frontend Tool | Unreal Engine 5.1 Documentation
If you’ve read through it and you’re still having issues let me know what part specifically you’re having trouble with and I’ll see what I can do.
