Artstation Just Announced FAB.com
which will merge Arstation Marketplace, Sketcfab, UE Marketplace, and Quixel Megascanes into one, FAB.com big Market
and the First question of course "What will be with Artstation Marketplace here ?"
the answer I found on FAB.com - "Creators offering free or paid products across UE Marketplace, Sketchfab, and the ArtStation Marketplace will be able to continue selling on those platforms during Fab’s Alpha period. Later this year, UE Marketplace, Quixel, Sketchfab, and ArtStation Marketplace will all roll up into one destination: Fab. Many of their product features will be integrated into Fab to create a unified experience that brings together our best features and creator communities."
