To create a frame by frame sprite animation in Unity, you should first draw or render out the animation frames from a 3D package, combine them into a sprite sheet, and import the sprite sheet into Unity (see the Exporting a 2D sprite animation from a 3D package recipe). You can also download the provided example Unity project and go to Chapter 03 2D and user interface animationRecipe 02 Creating a frame by frame sprite animation with the animation view directory. You will find a scene called Example.unity there, with a Coin game object that has been already animated. You can select it and go to Window | Animation to see how the animation was prepared.
