Low Marketplace Sales

Update
Epic’s new digital marketplace, when it launches in October. Fab will fully replace Unreal Engine Marketplace, which means that once Fab launches, you will no longer be able to purchase assets on UE Marketplace.

If you have acquired items from UE Marketplace over the years, you will have access to the UE Marketplace-licensed version of the content in Vault. After Fab’s launch, if a product has been updated to include additional file formats, it will be available for download on Fab.com.
For more information, check out [today’s announcement]

If the seller had declined to update the product this means it wont be available on FAB.

This means you must save all your Vault these locally (Many GB space required) and backup to USB

ALL UE 4. assets must be downloaded NOW, the will no appear on FAB.*
