It seems Microsoft is also working on an “unnamed project” to bring some of Wallpaper Engine’s functionality to the Xbox. This scoop comes from a well known Microsoft leakster, Aggioramenti Lumia, who posted a gif of the unreleased application on Twitter.

The “Xbox Dynamic Backgrounds Editor” also showcases a timeline where users can easily drag and drop to apply new effects. There’s also the option to add custom assets into the scene from the editor.  https://twitter.com/tomwarren/status/1525924592686141443?s=20&t=N141t9xKeHsLNFNJTUWtaA Unfortunately, it seems the new tool is only intended for game developers. Most likely aimed to streamline the development of new dynamic themes. To be fair, dynamic wallpapers have been a thing on Xbox for a while now. But they are very basic in form and don’t offer any customisation. While user customisation will still be missing in the event of a limited release to developers, we will atleast get more interesting dynamic themes to choose from.
