The broken glasses are only in Blender file. I'm not sure why they are not exported in OBJ and FBX. But even in the Blender file, the broken meshes are not clean. There are many issues with these broken meshes. You will need to work a lot to clean them up to be useful in the project. The exported meshes are triangulated so there is less scope of even fixing them correctly. I wish the artist had exported the mesh in quads because that's possible and the broken pieces were checked for the errors before putting on sale.
