Need a little help with some basic masks stuff, I've done this before and I am just having a total brain fart on how to do it think Ive been looking at a screen to long lately and my brain is fried.
I basically need a mask to stay still while a object flies towards it and disappears when it reaches the mask. Having trouble moving the image and the mask seperately. The effect I am trying to create is a bunch of letters/bills flying into a mailbox and filling it up. I thought it would be easy to put the mask on each bill/letter layer and have them disappear when they reach the mailbox. If anyone has any suggestions on a different way of achieving this effect it would be much appreciated.
