Key Notes
- Tim Sweeney says Epic is working to remove AI-training restrictions on Unreal Engine and MetaHuman outputs, but he has not announced an effective date.
- Developers would still choose whether their own games permit AI training, so the proposal is not blanket permission to reuse every Unreal Engine game.
- The published engine agreement still contains AI restrictions, while separately licensed content and NoAI-tagged assets remain distinct from the proposed output changes.
Epic Games plans to remove licence restrictions on using outputs from Unreal Engine and MetaHuman to train AI, according to CEO Tim Sweeney. Individual developers would still be able to permit or restrict training on their games through their own terms.
Sweeney outlined the plan in an October 27 response to Kotaku’s criticism of game companies embracing AI while protecting their own intellectual property. He described the EULA changes as work in progress, without announcing an effective date or publishing replacement wording.

The Published EULA Still Contains AI Restrictions
The current Unreal Engine agreement still restricts using the Licensed Technology as training input for generative AI, including prompt-based input where the AI trains on that data. Its language distinguishes the engine technology from products developers create with it.
A separate clause covers MetaHuman digital characters and animation curves, including rendered output crafted to replicate MetaHuman functionality, when used to build or enhance databases or train or test AI systems. These are specific contractual restrictions; Sweeney’s post does not supply a revised clause showing exactly how Epic intends to replace them.
That makes the announcement a policy direction rather than an already completed licence update. It also leaves open the precise scope of any new permission. Removing a restriction on outputs should not be read as a promise to open all engine code, marketplace assets or finished games for unrestricted reuse.
Game Developers Would Retain Their Own Choices
Sweeney’s central distinction is between Epic’s rules for its tools and a developer’s rules for a released game. In his description of the planned change, each game can still ship with terms that allow or prohibit AI training.
For a studio, the proposed flexibility would therefore concern what it can authorize for its own project. For someone seeking training material, the fact that a game uses Unreal Engine would not, by itself, establish that the game’s developer has granted permission.
The CEO also rejected the idea that Epic allows Fortnite intellectual property to be used without permission or compensation. His response treats rights in a game and restrictions attached to development tools as separate questions, rather than saying an AI-assisted recreation becomes acceptable simply because of how it was made.
Third-party assets introduce another distinction. Epic’s Content License Agreement separately prohibits using content marked NoAI in generative AI datasets, development or inputs. Sweeney pointed to creator choice and the NoAI tag when discussing material hosted on Fab; he did not announce that those protections were being removed.
What This Means for Game Production
MetaHuman is Epic’s framework for creating and animating digital characters, with tools for character creation and performance-driven animation. Its product overview describes uses ranging from game protagonists and NPCs to film and television production. Outputs therefore cover more than a conventional screenshot of a game in progress.
A studio interested in training on material it creates would need to distinguish that output from the underlying tools and any separately licensed content. The proposed revision could change Epic’s contractual barrier, while the developer’s own permissions remain part of the decision.
The announcement also follows other debates over Epic’s AI strategy. We covered Sweeney’s criticism of Steam’s AI disclosures and reported Epic’s decision to make AI optional for MegaJam after its original FAQ drew objections.
Those disputes concern how games are made and how AI use is presented. This proposal concerns what material may be used to train models. The next concrete development will be Epic’s revised legal text, which Sweeney has said is being prepared but has not dated.
