This transition will come with many changes, so I recommend reading the full announcement from Epic. For those short on time, here are the highlights:

• Fab will launch in mid-October with a wide variety of assets for Unreal Engine, Unity, and dozens of DCC tools, as well as UE5 and UEFN integrations, a real-time 3D viewer for inspecting assets, multiple license types, tiered pricing, and AI transparency. Sellers will earn 100% revenue share on products using Fab's Standard License until the end of 2024. After that, Fab will offer the 88/12 revenue share Epic has become known for.
• Unreal Engine Marketplace will no longer be available when Fab launches. Current sellers can begin migrating their products today. New sellers can sign up and begin uploading their products to Fab in early October. Product ratings will be migrated, but reviews and questions will not.
• Sketchfab Store will be replaced by Fab when it launches. Sketchfab.com will otherwise remain intact for now. Sellers can begin migrating their eligible models to Fab in early October. Product ratings will be migrated, but reviews and comments will not.
• Quixel Megascans content will move from Quixel.com and Bridge to Fab when it launches. Content will remain free for everyone under Fab's Standard License until the end of 2024. In 2025, Fab will begin charging for Megascans, though some content will remain free. You will retain access to any content previously acquired through Quixel.com and Bridge.
• ArtStation Marketplace will move to Fab in 2025, and sellers will be able to migrate their assets ahead of launch. All other parts of ArtStation will remain where they are.
