Evan Abrams hosts a look at how to get random particle like movement in an After Effects project, while still maintaining control over each of the elements in the group, by using shape layers and expressions. This will provide the look of a particle group, however will still give you control over each of the group’s elements.
What if you want random ‘particle-like’ movement in your After Effects project, but more control over each of the elements in the array?
Evan shows how to create an array of Shape Layers, giving the elements in the array some random movement while still allowing for control such as applying keyframes, size and position changes to individual elements. Check out the tutorial for Creating an After Effects Shape Layer Array here.
