Unfortunatly Grouper is PC only & I am Mac user. I can delete parts in the vertex modeller but it is increadibly difficult & time consuming as there are so many verticies to pick out of a complicated looking mesh. But thanks for trying guys.

Anytime I see something screech across a room and latch onto someone's neck, and the guy screams and tries to get it off, I have to laugh, because what is that thing?
