In UEFN we can do (almost) everythin we want, but there is one thing we players will always do, try out unreleased weapons/items before they release or even weapons that are not in BR/Creative.
So I thought why not allow us, players to play with unreleased weapons/items and be able to save them in vending machines, weapons spawner etc…
As long as we don’t publish our maps (showcase on youtube as well) we won’t get in trouble and avoid copiright issues (like marvel stuff or star wars)
From my understanding, there’s a process that needs to take place to optimize weapons/items for creative/UEFN. If Epic Games haven’t put the weapon/item in creative/UEFN, there’s a good chance that the weapon/item haven’t gone through this process. With that being said, if you add weapons/items that are not supposed to be in creative into creative/UEFN, you could be causing server issues and other unwanted issues.
