Project and Asset Security in UEFN

Unreal Editor for Fortnite (UEFN) is a powerful game development tool that includes advanced scripting capabilities. These capabilities make it possible for you to create complex and unique gameplay, but they also come with some risk to your data and your computer.

As long as you’re working on your own, the chance of something going wrong is minimal. However, when you work with other people, or when you download other people’s work for use in your projects, there is a potential risk of introducing content that accidentally or maliciously breaks your project, executes arbitrary code, or gets undesired access to your computer.

You can minimize these risks by only opening projects and assets that come from people you trust.

This page summarizes the most common actions you can take in UEFN that may expose you to risk and what you can do to reduce that risk.

Opening a UEFN Project

UEFN projects can contain scripts that execute code and access data on your computer in ways that you may not be aware of and may not be comfortable with. If you copy or download a project authored by someone else, and you open that project in UEFN, you expose yourself to the risk of these scripts running on your computer.
