Facebook has just updated their new feature that enables 3D viewing in posts... This feature has been around for some time, but the new update supports the industry-standard glTF 2.0 file format. This allows us to share 3D content on Facebook, whichever the designing software used was. Here I'll show you how to turn your 3D files into GLB, the only extension Facebook reads till now. By the way, GLB file format is a binary form of glTF that includes textures instead of referencing them as external images, so don't worry about the output's quality.
