Disconnected mesh, does it affecting when we doing rigging?

Hello everyone,

i just recently learning about rigging and i have created a model (only it’s head though).
i want to know, if create a model, does it matter if the mesh isn’t connected to each other
(like the image below, the head and ear doesn’t connected).

will it affect later when i am rigging the character?


yeah, i’ve already try it and it doesn’t seems natural when i move it.
i thought it because i am making some kind of mistake when rigging the model.
thanks a lot for your suggestion, arul
