character splits in half when moving leg I'm new to Blender and playing around a little bit, trying to make a decent enough character that can walk and what not. My problem is, so far all of my rigs seem to split in half when I move the leg. The lower torso moves with the leg and the belly pretty much gets cut open up to the belly button. 



When I modeled the character I applied a mirror modifier. Could that be the reason? If so, what did I do wrong?

Is there any way to fix this without having to start over?

Thanks!
To avoid this problem you should had the "clipping" option checked in the mirror modifier. Now simply go to rest pose (select all bones, then press Ctrl+G, Ctrl+R, Ctrl+S), then in edit mode select all and remove doubles, or manually join (Alt+M) the unconnected vertices, which probably are one on top of the other.
