According to Adobe, the software's beta build already has the new feature.
Adobe announced that the upcoming version of Photoshop will come with native support for Substance 3D files, meaning Substance users will soon be able to import procedural materials in .sbsar format into the software. According to the announcement, the new feature has already been added to Photoshop's beta build and can be tried and tested by Creative Cloud subscribers.
Unfortunately, not much has been revealed about the new feature's functionality. The team has only commented that the upcoming update will come with "parameters and lighting configuration". Adobe's Product Manager Jeanette Matthews, however, also added that it will soon be possible to "use the Substance files on any 2D layer as a 'fill'".
