I want to make a flock of birds using particle playground. I drug particle playground on to the bird layer and mapped it to the bird. At that point many birds show up but they are confined to only a portion of the screen. How do I get them to be able to fill the screen while keeping their original size?
There are several possibilities here: if your birds are on a precomped layer smaller than the final layer, PP uses the layer at its original size; if you're spawning your particles from a grid, there's a setting for grid size (width, height) that may be smaller than your comp.
