I wondered if I explained myself there 😅

I’ve got a shape that is the letter O, and would like to use it as a mask and transition the opacity of the mask until it fills this half tone pattern. As seen in the screenshot here.

Thanks Walter, I’m not sure that particles are what I’m looking for as I have the dots in 100 layers, I thought I might try using Falloff in the Motion plugin to animate these layers in.
