how to animate dots in sequence I'm new to After Effects and wondering how that's possible to animate opening for this map so each dot appears individually? I know how to make the opening using the mask but it shows the edges while I'd like to have "popping one by one dots" animation.Please see image below:
This tutorial can help you:


                
            

You will find there how to make dotted effect from scratch (use outlines of the map). Then you shall add some key-frames for animation.

To make dots appear more random, you can use Fractal Noise as animated mask. 

Good luck!
