Hi all, I'm having a bit of a mental challenge with a request I've received. Our designer wants to be able to take a single image and animate a bunch of triangles as masks to slowly reveal the image triangle by triangle. I know I can use sprites and shapes as a mask to the image, but it only seems like I can use 1 triangle at a time as the mask. Is there a way to animate a bunch of shapes in a single sprite and use that sprite as the mask?    Thanks!
