In Photoshop, clicking "3D - Get more content" used to take you to a site with materials compatible with Photoshop. It now takes you to the Adobe 3D site https://www.adobe.com/uk/creativecloud/3d-augmented-reality.html which is fine as an advert for the 3D subsription packages but useless as a means of getting content for Photoshop (the SBSAR format is not compatible).
