how to turn off x ray in particle edit mode? I'm trying to Comb my subjects hair, but it seems as though as if a kind of x ray mode is turned on and I don't know how to turn it off.


As you can see, the hair particles are going right through the bear and whenever I comb, it also counts the movement on the back of the bear's fur too.
I had the same problem. Just press the 'limit selection to visible' button. 
In particle or edit mode, 3d view bottom left, next to the propotional editing mode.
