    Hi All

    I was wondering how do you get a map of say USA to slowly fill with red dots, this is similar to the way Plague INC did with their map.

    So I wondering how do you do such an effect on a map??

    There are many ways to do so. For instance, create a perlin noise texture and push it to shader. Add _Level float property to that shader and in fragment function draw red if noise > level, otherwise draw original color. Then slowly increment level.
