Why is proportional editing only effecting one side of my mesh? I'm currently working on facial expressions and using Shape Keys and I've just run into this weird problem...



Whenever I manipulate one side using Proportional Editing, the other side won't follow or match, no matter the size of the fall-off. It's like the other side just stays where it is. I'm not sure what's happened. There are no modifiers active or waiting to be applied, such as the Mirror.



I can't figure out what's wrong. Any ideas?
You probably have to disable the X Mirror option in the Tools Options panel
