Your Master Project tasks for this lesson consist of adding two particles to your project. First, you'll add snow to the scene, with the snow beginning when the first two leaves fall from the tree. The second particles you will apply will be the Leaves Life Cycle particles that you created. If you're up for the challenge, you can also re-create the Leaves Life Cycle particles from scratch for practice.
To help you along, I've included a finished movie and a finished Master Project file for this lesson for you to use as a guide. Good luck, and have fun.
