Using an image sequence in a particle emitter

So far, all the content we've used for our particle emitters has been through selecting presets or using content through Motion's library. In this recipe, we're going to find a collection of photos on our drive to bring into Motion and use them as the source for our particle system.

Getting ready

Locate a collection of around 20 photos on your hard drive. It's best if these photos aren't extremely large in size, because we will be displaying several of them onscreen at once. Feel free to use your favorite photo-editing application to scale them down. We want Motion to see these photos as an image sequence; to do that, we'll need to give them the same name followed by a numerical number. The numbers assigned should be sequential. For example, if you have a set of photos with buildings, you'll call the first photo building_1, the second building_2, and so on. Once this is finished, launch Motion and choose a project with Duration set to 10 seconds...
