Some 3d applications do support Allegorithmic .sbar files natively in their materials. For example, 3dsMax can open .sbsar library formats from software like Bitmap2Material or Substance Designer, etc. natively inside the material editor for use on models. I believe Modo also has support for this. However, I don't think Allegorithmic has supplied Blender with direct support yet, so the files would have to be converted to PBR maps and textures and used that way.
