Lore is available under the MIT license and has been used internally as Unreal Revision Control in Unreal Editor for Fortnite. The current release is pre-stable, with APIs and protocols subject to change.","whyItMatters":"Lore addresses a long-standing gap in game development tooling by combining Git-like hash-based data handling with centralized access control, reducing storage and transfer costs for multi-gigabyte asset files.","webCardHtml":"\u003cp\u003eEpic Games has released Lore, an open-source version control system built for game and entertainment production. Lore handles both source code and large binary files such as images, audio, and 3D models, and is available under the MIT license. It stores files by splitting them into small fragments and reusing common fragments between versions, which reduces the data needed for storage and transfer when only small changes are made to multi-GB files. Developers can fetch only the source code area, while artists can handle only the assets they are responsible for, and everyday editing operations like staging, committing, branching, and diff checking work without server communication.\u003c/p\u003e","blueskyPost":"Epic Games open-sourced Lore under MIT, but the pre-stable label means APIs and protocols will change.
