We are also happy to announce that we are releasing an updated 3D model obj exporter today that will work with the latest version of the game. This will allow you to create 3D prints of your creations and upload them to sites like Sketchfab, opening up many new ways to share what you build in Space Engineers. You can even add a Sketchfab model to the Steam Workshop page of a creation, providing an interactive preview to other players before they use it in-game.
