Working with and manipulating multiple cells
In an earlier recipe, where we looked at particle presets in detail, we saw that an emitter can reference multiple cells. Let's take a look at how we can add additional cells to our project.
Getting ready
From this chapter's exercise files, double-click the 07_08 project. Play back the project. There is a particle system in the project with one cell that's referencing the Atomic Cluster layer. By changing the values in the Inspector, I was able to change the color of the atoms over its life, have them fade in and out, and emit straight towards us. A gravity simulation behavior was added, so the particles appear to be falling too. In the Layers tab there is a group called Atom 02. We want this group to move with our particle system. We'll duplicate the existing cell and change the source. We'll also change the Random Seed value so that the objects don't occupy the same space.
How to do it...
Select the Atom Cluster cell and press Command + D to duplicate...
