In April 2025, Epic acquired Loci, an AI company whose tools automatically tag, label, and categorize 3D digital assets using computer vision. The technology is being integrated into Epic's Fab marketplace to improve how artists and developers search for and find 3D content — and to help detect stolen or duplicate assets.
Details
Loci was founded by AI researchers from Cambridge, MIT, and Oxford, and its machine learning models were trained on over one million 3D assets. The system uses computer vision to analyze the visual and structural properties of 3D objects and assign searchable tags automatically — a task that previously required manual effort from content teams. Beyond discoverability, Loci's 3D similarity detection capability is being applied to identify stolen intellectual property in marketplace submissions and flag AI-generated content. The technology directly supports the content moderation effort described in Practice 9.

Other practices by Epic Games
OtherAfter widespread protests from artists in December 2022, Epic's portfolio platform ArtStation introduced a "NoAI" label that artists can apply to their work to signal they do not want it used in AI training datasets. Epic also updated its terms of service to commit that it will not use or license any ArtStation content — labeled or not — for AI training purposes.OtherEpic provides a plugin for Unreal Engine 5 that lets game developers train AI-controlled characters and agents by having them learn through trial and error — similar to how a person gets better at a task by practicing. The tool, called Learning Agents, launched as an experimental feature with Unreal Engine 5.3 in September 2023 and is aimed at developers, not players.OtherUnreal Engine 5 supports NVIDIA's DLSS technology, which uses AI to make games run more smoothly on compatible graphics cards by generating additional frames and sharpening images — without the full processing cost of rendering everything natively. Epic has also integrated NVIDIA's ACE tools, which give developers AI-powered options for animating digital human faces and generating NPC speech.
