remember that you dont have to create a, so called, vector mask when using the shape tool. you can create a path instead or even just fill the shape with pixels. This last option kinda defeats the object of the shape mask (as I call it) but you might find a shape you want and know you wont need to make changes to it but will have to rasterize it, as if it was not already rasterized, LOL.

To do any of these options make sure you have the right option selected from the option bar, that’s the Horizontal options that become visible for each tool selected, right under the menu bar.
