Bases: MayaInstancePlugin, OptionalPyblishPluginMixin
Validate meshes have only vertices that are connected to edges.
Maya can have invalid geometry with vertices that have no edges or faces connected to them.
In Maya 2016 EXT 2 and later there's a command to fix this: maya.cmds.polyClean(mesh, cleanVertices=True)
In older versions of Maya it works to select the invalid vertices and merge the components.
To find these invalid vertices select all vertices of the mesh that are visible in the viewport (drag to select), afterwards invert your selection (Ctrl + Shift + I). The remaining selection contains the invalid vertices.
