Supporting Mods and UGC in Your Unreal Engine Game | Unreal Fest Bali 2025

Adding modding and UGC support can be a complicated endeavor with a lot of moving parts. In this session recorded at Unreal Fest Bali, mod.io walks through adding UGC support to Unreal Engine titles, whether from the ground up for a new title, or retrofitting support into an already developed or shipped title.

Mod.io has supported many Unreal Engine studios ship mod support in their titles, and has a wealth of knowledge about common challenges, solutions, and benefits in adding UGC support to a game, including support on consoles.

This talk covers a variety of topics, including the benefits of adding UGC support to your game; cooking your game to prepare it for UGC; examples of simple patterns to follow for mod support; gameplay messaging style of behavioral modification; scripting support; and distributing an editor to your end users for creating content.

Mod.io provides an open source link to the code discussed in the talk at the end of the presentation.
