You cannot use Unreal Engine or MetaHuman assets to train any AI or machine learning system. This includes using engine outputs, character models, or animation data as training data for generative AI tools.
This analysis describes what Unreal Engine's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
Studios increasingly use AI tools in their production pipelines, and this prohibition may restrict or prohibit workflows where Unreal Engine outputs are used to train or fine-tune AI models, including internal tools.
Interpretive note: The scope of 'rendered output thereof if crafted to replicate the functionality of MetaHuman' is ambiguous and may require legal interpretation to apply in specific production contexts.
Developers who use Unreal Engine-generated content as training data for AI systems, even for internal or research purposes, would be in breach of this agreement, which could affect AI-forward studios and researchers.
How other platforms handle this
Microsoft reserves the right to restrict the export of data that may compromise the security of the services or Microsoft's intellectual property.
Datadog reserves the right, but does not assume the obligation, to investigate any violation of these Terms or misuse of the Site.

"result in using the Licensed Technology as a training input to any Generative AI Program or as prompt-based input where the Generative AI Program trains on input data. 'Generative AI Program' means artificial intelligence, machine learning, deep learning, neural networks, or similar technologies designed to automate the generation of or aid in the creation of new content, including but not limited to audio, visual, or text-based content; or use, or permit others to use, MetaHuman digital characters and animation curves (or any rendered output thereof if crafted to replicate the functionality of MetaHuman) to build or enhance any database or training or testing any artificial intelligence, machine learning, deep learning, neural networks, or similar technologies.Excerpt from Unreal Engine's EULA
REGULATORY LANDSCAPE: The contractual prohibition on AI training inputs interacts with the emerging EU AI Act, which imposes transparency and data governance requirements on AI system developers.
