I have a problem with AE CS6 and shapes. I'm doing a complex shape made of multiple shapes and some of them need to be substracted. So I did all shapes in a shape layer and when I arrived at the moment of making some substracted shapes I find out that the resulting shape is showing behind the rest of the shapes despite puting them above all. No matter if I group them, the result is the same. Here's a SS of the shape stack
Any idea about why is this happening and if it is possible to do it in the same shape layer?
