Question
__I am not a smart man* (*when it comes to AE)... need help with Masks - specifically making a mask
I want to make a mask from a vector object (let's say a hexagon).
I have footage of a store, which I want to mask with this object for only part of the duration (not a track matte, since it seems like I can't make it appear/disappear etc.)
How on earth do I do this?

I know a lot of you will say "This is basic, dumbass!" - to them I say, yes, I am a dumbass when it comes to AE which is super complex, and I'm 100% self taught.
