Instructor Notes

Watch this video for additional guidance in accomplishing this exercise. Though, I encourage you to watch only after attempting the exercise first. Otherwise it defeats the intention of the exercise being a challenge in application of the information learned in the Fundamentals of Mecanim Course. Additionally, Completed files have been included in the Downloads tab to show how this was created.
