Hey I want to connect these ears to this head. The thing is I want to rig it later and I'm worried that if I don't actually join the two meshes together it will look weird if I move the ears with a joint. Would it work regardless or do I need to connect both meshes. If I have to connect them the problem I have is that obviously there are aren't enough vertices on the head to properly connect the ears to it. I know about adding a new edge or also subdividing so that's really no problem. What I want to know is if this is absolutely necessary or if there's a way to connect these 2 objects together without doing this.

W> Bridge edge loops). Since it's kind of hard to make separate objects which match perfectly, I think the easier solution is to extrude the ear out of head. – gandalf3 May 09 '14 at 00:28
